I do not have the schematic or instructions for testing in PDF form. I tested the diode in the proper selection on my DMM. Pins #4 and #5 are continuous with each other so reading 12 volts across is proper. About a year ago I had another electrical issue with this car and during my investigation...
The coil with the double winding runs the fuel pump. The coil with the diode runs the idle control servo motor, the purge control solenoid, and the air temperature sensor. I have the factory service manual for this car and in it there is a very detailed description on how to test this relay. The...
Thanks to all who responded. The diode is in series with the coil. I have purchased 2 new replacement relays which also tested bad and were returned. I am testing the relay per the instructions in my service manual. The relay does make the audible clicking noise indicating closure of the...
I have a 1992 Dodge Stealth with a relay that no longer works, The circuit is fused for 15 amps and is 12 volts. After some investigation I have determined that a transient voltage suppression diode, which was soldered into the relay, is open. This very tiny diode has the number 77 on it and...
