/GAUNTLET™ ELECTRONIC RELAY DIAGNOSIS
***The following tests must performed using a digital volt meter***
***All tests must be done with power off***
Verify the Relay Resistor Assembly
1. Field circuit - unplug the brown wire from field terminal
•TP2 (red lead) to end of brown wire (black lead)
· This will test diode #2
· Digital Volt Meter (DVM) on diode check range should = .466
· DVM on ohms = 1.5 or less
2. Relay Circuit - These tests will determine whether or not the relay is shorted within itself or from B+
to normally open post (this is normal only while under console control).
· •TPA (red lead) to TPC (black lead)
DVM on ohms = OL. This tests whether or not the load resistor is shorted to B+ when relay is normally
closed (should be B+ to field).
· •TPA (red) to TPB (black)
DVM on ohms = OL. This tests whether or not the relay poles are shorted together inside the relay
· •TPC(red) to TPB(black)
DVM = 1 ohm or less. This tests whether or not the relay is closed (it is normally closed).
3. Positive Output
· •End of white wire which is positive output at alternator (red) to TPC (black)
DVM = 1 ohm or less
· •End of white wire (red) to TPB (black) - through relay 3
DVM = 1 ohm or less. Confirms previous tests.
