Hey guys I've been having bit of trouble wiring my wiring in my ranger... Seem like my starter solenoid is sending ground to ignition system or something... I have replaced solenoid,battery,wires to battery,spark plugs/wires,distributor 2X,module,coil,ignition switch, timing on distributor and camshaft seems like everything and still can't get it to crank. The "S" prong on solenoid is sending ground....why is that? The Distributor wire sending ground to module..
Why is that? When i unplug distributor from module the coil gets complete volts...why is that?

 

Welcome to the forum

"S" post IS grounded(thru the coil), and should be, its connected to the "coil" in the starter relay
A relay works by one end of the "coil" being grounded, so when you apply 12volts to the other end, "S" post, the coil will magnetize and close the relay sending battery volts to starter motor

The "coil" is literally just a coil of wire around a metal core, in a starter relay(solenoid)one end is always grounded via the bolts to metal inner fender
So if you were to test OHMs or continuity on "S" post to ground it should show "connected" because it is

Same for pretty much all electrical devices, they all need a "ground" and 12volts to work, with only 12v they wouldn't work, there needs to be a "circuit" a circle, between battery negative and battery positive
As long as there is a "device" between the - and + its not a short, i.e. a light bulb needs both - and + to light up, remove either and no light
Most light bulbs will test as always grounded, add 12v and it lights up

 

Starter is grounded to engine...right? But it shouldn't send ground back up to solenoid should it?

 

???

Any Automotive(DC) device must have both a ground and 12volts to work
If device is activated by giving it 12volts then it is already grounded

So if you were to test the 12v wire to the device it would show as a ground, because its grounded
Its not "sending" anything its just grounded to battery Negative THRU the device

Starter relay BIG posts>XX-----------------------------------Starter Motor-----grounded to bell housing-----which is grounded to battery Negative

If you were to test at XX it would shows as a Ground if Big Post didn't have 12v

An electric motor is also just a coil of wire so passes the "ground" thru it to the 12v wire side

As said pretty much ALL DC electrical device's 12v wire will test as a ground when 12v is disconnected

If you "send" 12v to a device and it doesn't work then its either not grounded or broken

 

Anyone close to Macon,Ga that can look at truck? It's having wiring issues.
