Relays and Fuses

The relays and fuses and are located in the compart ment that is rear of the control panel (Fig. 18). There is an 80 ampere fuse (50 ampere on the GM 3000) located by the alternator (Fig. 22).

Relay Testing

1.Verify coil resistance between terminals 86 and 85 with a multimeter (ohms setting). Resistance should be from 75 to 95 ohms. There should be continuity between terminals 87A and 30.

2.Connect multimeter (ohms setting) leads to relay terminals 30 and 87. Ground terminal 86 and apply +12 VDC to terminal 85. The relay should make and break continuity between terminals 30 and 87 as 12 VDC is ap plied and removed from terminal 85.

3.Disconnect voltage from terminal 85 and multimeter lead from terminal 87.

4.Connect multimeter (ohms setting) lead to relay ter minal 30 and 87A. Apply +12 VDC to terminal 85. The relay should break and make continuity between termi nals 30 and 87A as 12 VDC is applied and removed from terminal 85.

5.Disconnect voltage and multimeter leads from relay terminals.

Fuse Testing

Note: Prior to taking small resistance readings with a digital multimeter, short the test leads together. The me ter will display a small resistance value (usually 0.5 ohms or less). Subtract internal resistance of the meter and test leads from the measured value of the compo nent you are testing.

1.Use a digital multimeter and check continuity of fuse.

2.Resistance of fuse should be less than 1 ohm.
