Starter Solenoid ???????? Help
 

On my sons 1982 c2500 2wd 6.2 Diesel the starter stopped working. I suspect it was the solenoid on the starter so I purchased a solenoid from Oreillys, there quite a bit $$$$ difference so you'll know why I'm trying this first. Now the old solenoid has two relays, one I believe for the battery (power) the others for the starter switch it has an "S" by it. Now my dillema, the new solenoid has 3 connections, the large main for power then two smaller ones one labled "S" the other "R", I know I need to connet the main and the "S" but is this going to cause a problem if the other relay is left unconnected, and what would I connect. If you can offer ant advice I would certainly appreciate it. I truly hate electrical problems also its 108 degrees here today.

Thanks guys.

One should be a start relay and the other should be a charging relay. That's how my 86 CUCV is and that portion of the wiring isn't any different than the civilian models.

But currently there is no thrid wire to hook up the solenoid, there are only two.

I replaced the solenoid on my starter and it had three connections. I only hooked up the two like you're proposing and it worked fine!

I understand now. Just hook the two wires up and you're good to go. The third post (R) on the solenoid was used primarily on points systems. It's not used on most wiring harnesses anymore.

The third wire is for vehcles with ignition points. It supplies 12 volts during starting to the coil. Run position the coil only gets 9 volts on some early models.
