Starter relay question
Isn’t this just a ford starter switch with a different bracket & spade lugs instead of screw terminals?
No not necessarily and that is my *****........modern internet driven parts do NOT show proper specs
There are several ways solenoids can be wired, examples:
1...Ford solenoid coils are grounded, the power terminal to activate the solenoid is "S". The "I" terminal is a separate contact, used for the coil resistor bypass,.........."grounded base"
2..Some starter solenoids, and most all "continuous duty" solenoids, the coil is brought out to the two small terminals, "insulated base"
I BELIEVE NO2, ABOVE, IS HOW THAT THE SOLENOID IN DISCUSSION IS WIRED so that it works with the neutral switch
3..There exist some "Ford look" solenoids, which are wired like Ford, AKA with the Ford style "I" bypass, but the coil is not grounded. The coil is "S" terminal on one end, and the other coil is brought out to a 5th terminal on the other side of the unit. These are used on some AMC/ Jeeps because of the Chrysler Torqueflite neutral switch, and using a Ford starter. "insulated base"
4..Some old Ford, both 6 and 12V used for trucks, tractors, industrial, and older, 6V Ford cars, have the power end of the solenoid internally connected to the large battery terminal, the other end brought out to the single small terminal. These use a one-wire, grounding starter button, unique to Ford I think. This also means the battery MUST be connected to the proper terminal, otherwise the solenoid will not engage. Cause for false returns "it don't work."
"insulated base"
5...More modern Ford cars (late 70's/ 80's?) deleted the "I" terminal as electronic ignition did not use a resistor. "grounded base"
ALL of this used to be detailed in the manufacturer's pictorial list, such as NAPA Echlin or Standard Motor Products.
