Wiring
. Relays are my wiring bane.
In what way? Maybe we can dispel some of that bane?
1...."Ford like" starter solenoids.........Many guys use these, and for various setups but you do have to understand, you cannot just "look" at them and figure what they are. Some have the coil grounded (Ford) some have an additional post for NSS (AMC/Jeep) and some aren't "Ford" at all, they are "continuous duty" meaning they have a coil magnet which can put up with being on for "constant" use. In short, these solenoids are wired differently and might look alike
2....."Bosch" relays......slang term for the cube relays you see in modern cars, these kick *** because they are SO available, BUT THERE ARE some caveats........They are NOT all the same. Some have heavier connector terminals and some have these paralleled for more current
Regardless of 1, 2, above, ALL relays have a magnet coil which may or may not be rated for continuous use, and which may or may not be grounded to the mounting. Therefore it turns on and off.
All relays have some sort of contacts, but some are "normally open" like a horn, starter relay, and others are "normally closed" meaning that you turn on the relay coil to "drop" the circuit."
Questions?
The Mopar typical starter relay is a GREAT example of how relays "get used." They put the NSS / clutch in the ground lead which makes the circuit somewhat more simple, and the thing made a really handy place to jumper the starter LOL
