Important Safety Information It is your responsibility to be completely familiar with the WARNINGS, CAUTIONS, and NOTICES described in this Electrical Schematics Manual. These highlighted messages advise against the use of specific service methods or procedures which can result in personal injury, damage to the equipment, or unsafe operating conditions. It is important to understand that these messages are not exhaustive. Gillig Corporation could not possibly know and evaluate all conceivable methods in which service might be done, nor could they advise the service trade of all possible consequences of each method. Therefore, Gillig has not undertaken such a broad evaluation. Accordingly, anyone who uses a service procedure or tool which is not recommended by Gillig Corporation must first be thoroughly satisfied that neither personal safety nor equipment integrity will be jeopardized by the service method selected. The WARNINGS, CAUTIONS, and NOTICES appear at appropriate places of the manual in special print. It is critical to the safety of service personnel and the coach that these warnings are diligently observed, especially while undertaking any of the procedures presented in this manual. WARNINGS, CAUTIONS, and NOTICES appear as follows:

Appears when an operating or service procedure, if not cor- rectly followed, could result in personal injury or fatality.

Appears when an operating or service procedure, if not strictly observed, could result in injury to you or damage to the equipment.

Highlights an operating or service procedure which is essential for proper operation, maintenance, or repair.

Vehicle Identification Number (VIN) The Vehicle Identification Number (VIN) and other information about the coach is found on the Manufacturer’s ID plate which is located on the door of the main electrical panel above and to the left of the driver. The VIN serves as a legal identification number and appears on the vehicle certificate of title and registration papers. You may be asked to provide the VIN to Gillig Service or Parts personnel in order for them to properly investigate and answer your inquiry.

How To Use This Manual This manual simplifies the task of electrical troubleshooting on your Gillig Low Floor Coach. It is customized for your specific coaches, using the “As-Built” Bills of Material and associated Electrical Schematics. The electrical schematics and wiring diagrams in this manual are arranged in chapters covering the type of system in which they are employed. An extensive table of contents will help you identify the draw- ings or circuits included in this manual. A cross reference listing is provided in the Index to correlate drawing numbers with page numbers, so that you can find a drawing if you only know the Engineering drawing number. Page numbers are consecutive thru the manual. Heavy tabbed divider pages separate the chapters to assist your search.

Troubleshooting Equipment Volt-Ohm-Milliammeter (VOM). A volt-ohm-milliammeter is a single test device in which the functions of a voltmeter, ohmmeter, and ammeter are combined. It may be used to check voltage, check for a short to ground, check for continuity in a circuit, measure current, or to check to verify a ground. Voltmeter. A DC voltmeter is used to check the DC voltage to ground. There are two test leads: the negative lead, which is connected to the ground side of the circuit; and the positive lead, which should be connected to the hot side of the circuit. Ohmmeter. An ohmmeter may be used to measure resistance between two points of a circuit.

An ohmmeter must only be used on de-energized circuits. An energized circuit may cause meter damage or result in inac- curate resistance measurement. Jumper Wire. A jumper wire may be used in trouble shooting procedures to bypass certain circuit components or circuit segments where an open is suspected. A jumper is a length of wire with clips or terminals used to connect two points of a circuit.

Do not use a jumper wire to bypass high resistance loads, as this would short to ground and may cause damage to the circuit and/or injury to maintenance personnel.

Troubleshooting Procedures Troubleshooting is a systematic approach to solving problems. Since there are many components and connections in an electrical circuit, it is necessary to follow a step-by-step procedure for an accurate diagnosis of any electrical problem. First, verify the problem or complaint by operating the circuit in which the problem is suspected. Once the problem is identified and verified, then refer to the Service Manual and the Electrical Schematics Manual to inspect the schematic for the circuit in question. Next, trace the circuit and redraw it if necessary. This will help identify the connections, splices, grounds, and components in the problem circuit. After tracing the circuit, systematically test for faulty components, connections, or grounds to identify the problem. Finally, when the problem is isolated and a particular component of the circuit is determined to be the cause of the problem, make the necessary replacement or repair. Then operate the circuit to verify the repair.

Open Circuits Many electrical system failures are caused by an open circuit. An open circuit is one in which power flow stops because of an interrupted or incomplete circuit path. An open circuit is caused by an im- proper ground, a loose or broken wire, a broken connector, a poor terminal contact, an open or faulty component, or a fuse or circuit breaker opened because of a short or overload. Testing to isolate an open circuit can be done by using a jumper wire to bypass a suspected open element. If the circuit operates with the jumper in place when the power is applied, then the open is in the segment of the circuit which was jumped or bypassed. Another procedure to pinpoint an open element in a circuit is to test for power along the circuit using a VOM. If the VOM indicates power at one point in the circuit, then is moved along to another point of the circuit and does not indicate power, the circuit is open between the two points. A third test, again using a VOM, can be conducted to detect an open in a component. First disconnect the component from the circuit. Then connect the leads of the VOM to the component. If there is no continuity, an open exists in the component.

10 Short Circuits Many electrical system problems are caused by short circuits. A short circuit is either a feed circuit which has been completed to ground before it reaches the intended operating unit or a ground circuit that is grounded prematurely. To diagnose a short to ground, use a VOM to test for continuity to ground. First, disconnect the circuit from power and ground. Next, connect the VOM between the circuit and ground. There will be continuity if the circuit is shorted to ground. To isolate the short, open elements of the circuit one at a time until continuity is lost. The short is in the last element opened or in the segment of the circuit beyond the last element opened. To pinpoint the short, test each element of the isolated segment. A tripped circuit breaker or blown fuse usually indicates a short to ground. Use a VOM to isolate the short. First, turn off all elements of the circuit receiving power through the circuit breaker or fuse and disconnect all loads. Turn on power to the fuse, then connect one lead of the VOM to the power supply side of the circuit protector and the other lead to ground. The VOM should indicate power. Next, disconnect the ground lead of the VOM and connect it to the load side of the fuse. If the VOM does not indicate voltage, the short is in the disconnected equipment. If the VOM indicates voltage, the short is in the wiring. To pinpoint the short, disconnect circuit elements one at a time until the VOM does not indicate voltage. The short will be in the segment connecting the last element.

11 Welding Precautions Prior to performing any welding operation on the coach, sensitive electrical components must be pro- tected from damage. The sequence below must be followed in the order shown or damage to the voltage equalizer, multiplexer, or any of the electronic control units (ECU’s) may result. When the welding operation is completed, the components must be reconnected in the reverse order of disconnection.

Ensure the following precautions are accomplished prior to welding anywhere or anything on the coach, as permanent damage to electronic components may result.

1. Place the main battery cut-off switch into the OFF position. 2. Disconnect the battery ground from the voltage equalizer. 3. Disconnect the battery cables from the batteries. 4. Disconnect the power connectors from the ECU’s and electronic equipment (ABS, engine, transmission, I/O DINEX multiplexing system, wheelchair ramp, destination sign, communication equipment, voice annunciation system, communication network (such as SAE J1708, J1939, etc.), surveillance system, and other electronic devices. 5. Disconnect the main power fuse from the multiplexer circuit (located in the lower driver’s console). The welding ground cable should be attached to a chassis member as close to the weld site as possible, consistent with good welding practices. Do not connect welding cables to, or weld on, control components. Protect components from heat, sparks, and spatter while welding. When welding is complete, reconnect the components in the reverse order of removal.

Use of Non-OEM Parts To ensure optimal coach operation, always use Original Equipment Manufacturer (OEM) parts and follow OEM-recommended maintenance procedures. Failure to use OEM parts may result in costly equipment failure.

Use of non-OEM “will-fit” parts can lead to costly failures! For example, installing a low-cost switch may result in a high-cost fire; using a low-cost filter may result in a high-cost transmission rebuild. Parts of lesser quality often fail, and can lead to costly problems that could compromise the safe operation of the coach. Always use OEM replacement parts. 12 Circuit Listing

ONCE IGNITION POWER IS APPLIED TO THE EM-70 AND D3-24 (INPUT) THROUGH THE 125mA FUSE AND GND IS APPLIED TO THE EM-70 THEN THE SYSTEM IS "ON" AND NO INDICATORS WILL BE ILLUMINATED. IF THE FUSE IS OPEN, THEN NO INPUT WILL BE DETECTED AT D3-24 AND IF THE FRONT IGNITION SWITCH IS IN THE ON POSITION THEN ALL THREE INDICATORS WILL TURN ON. TO EXTINGUISH THE THREE INDICATORS: RESTORE INPUT POWER AT D3-24

2. ONCE THE SYSTEM IS ON: THEN THE EM-70 WILL MONITOR THE 12 AND 24V SYSTEMS THROUGH THE 800mA FUSES. IF THE 12 VOLT SYSTEM IS LESS THAN ROUGHLY 1/2 OF THE 24 VOLT SYSTEM FOR APPROX. 5 SEC.: THEN THE EM-70 WILL PROVIDE A GND. INPUT TO D1-19. IF THIS INPUT IS ON THEN THE CHECK 12V INDICATOR WILL ILLUMINATE. IF 12V IS PRESENT ON THE BAT12V15 EM-70 TERMINAL THEN THE BATTERY EQUALIZER SHOULD BE TESTED FOR PROPER OUTPUT.

3. IF THE VOLTAGE AT THE +24V INPUT IS DETECTED ABOVE ROUGHLY 30 FOR APPROX. 5 SEC. THEN: THE EM-70 WILL OUTPUT A GND INTO D1-14. THIS WILL ILLUMINATE THE "HIGH 24V" INDICATOR. REAR ELECTRICAL PANEL 4. IF THE VOLTAGE AT THE +24V INPUT IS DETECTED BELOW ROUGHLY 24 FOR APPROX. 5 SEC. THEN: THE EM-70 WILL OUTPUT A GND. INTO D1-18. THIS WILL ILLUMINATE THE "LOW 24V" INDICATOR.

Multiplex System

Complete documentation of the Multiplex Electrical Control System installed in your coaches is published as a separate manual. That manual is the “Multiplex System” manual, which has been supplied along with this Electrical Schematic Manual. The Multiplex System Manual includes a listing of the nodes at each multiplex module, ladder diagrams for the many functions controlled by the system, and a cross reference table at the end of the manual for your added convenience. Please refer to that manual when attempting to troubleshoot or repair the Electronic Control Systems in your coaches. As with the other Gillig Manuals, an electronic copy of the Multiplex System manual is included on the CD which is provided as part of the manuals and documentation package supplied with your coaches.
