An extensive table of contents will help you identify the draw-ings or circuits included in this manual. A cross reference listing follows the Table of Contents tocorrelate drawing numbers with page numbers, so that you can find a drawing if you only know theengineering drawing number. Page numbers are consecutive thru the manual. Heavy tabbed dividerpages separate the chapters to assist your search.

Information in this manual is only for the Gillig Low Floor coaches designated on the front coverand again at the top of the Table of Contents page. Do not use this manual as a basis for troubleshooting electrical systems or circuits for any other Gillig coaches in your fleet.

WIRE COLOR IDENTIFICATION

Wire Color. Colors are abbreviated as follows:

TROUBLE SHOOTING EQUIPMENT

Volt-Ohmmeter (VOM). A volt-ohmmeter is a single test device in which the functions of both thevoltmeter and ohmmeter are combined. It may be used to check voltage, check for a short to ground,check for continuity in a circuit, 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: thenegative lead, which is connected to the ground side of the circuit; and the positive lead, which shouldbe connected to the hot side of the circuit.

LOW FLOORLOW FLOOR

Ohmmeter. An ohmmeter may be used to measure resistance between two points of a circuit.

CAUTION

An ohmmeter must only be used on de-energized circuits. An energizedcircuit may cause meter damage or result in inaccurate resistancemeasurement.

Jumper Wire. A jumper wire may be used in trouble shooting procedures to bypass certain circuitcomponents or circuit segments where an open is suspected. A jumper is a length of wire with clips orterminals used to connect two points of a circuit.

WARNING

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

TROUBLE SHOOTING PROCEDURESTrouble shooting is a systematic approach to solving problems. Because of the many components andconnections in an electrical circuit, it is necessary to follow a step-by-step procedure for an accuratediagnosis of any electrical problem.

First, verify the problem or complaint by operating the circuit in which the problem is suspected. Oncethe problem is identified and verified, then refer to the Service Manual and the Electrical Schematicsmanual 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 identifythe problem.

Finally, when the problem is isolated and a particular element of the circuit is determined to be the causeof the problem, make the necessary replacement or repair. Then operate the circuit to verify the repair.

SHORT CIRCUITSMany electrical system problems are caused by short circuits. A short circuit is either a feed circuitwhich has been completed to ground before it reaches the intended operating unit or a ground circuit thatis grounded prematurely.

To diagnose a short to ground use a VOM to test for continuity to ground. First, disconnect the circuitfrom power and ground. Next, connect the VOM between the circuit and ground. There will be conti-nuity if the circuit is shorted to ground. To isolate the short, open elements of the circuit one at a timeuntil continuity is lost. The short is in the last element opened or in the segment of the circuit beyondthe 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 theshort. First, turn off all elements of the circuit receiving power through the circuit breaker or fuse anddisconnect all loads. Turn on power to the fuse, then connect one lead of the VOM to the power supplyside 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 notindicate voltage, the short is in the disconnected equipment. If the VOM indicates voltage, the short isin the wiring. To pinpoint the short, disconnect circuit elements one at a time until the VOM does notindicate voltage. The short will be in the segment connecting the last element.

OPEN CIRCUITSMany electrical system failures are caused by an open circuit. An open circuit is one in which powerflow 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 faultycomponent, 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 ele-ment. If the circuit operates with the jumper in place when the power is applied, then the open is in thesegment 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 aVOM. If the VOM indicates power at one point in the circuit, then is moved along to another point ofthe 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 disconnectthe component from the circuit. Then connect the leads of the VOM to the component. If there is nocontinuity, an open exists in the component.

WELDING PRECAUTIONSPrior 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 voltageequalizer, multiplexer, or any of the electronic control units (ECU’s) may result. When the weldingoperation is completed, the components must be reconnected in the reverse order of disconnection.

CAUTION

Ensure the following precautions are accomplished prior to weldinganywhere or anything on the coach, as permanent damage to electroniccomponents 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, communi-cation 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 driversconsole).

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 compo-nents. Protect components from heat, sparks, and spatter, while welding.

When welding is complete, reconnect the components in the reverse order of removal.
