Thread: starting solenoid ?

Tweet

I have a chevy starting solenoid ,my question is there is the B-batt terminal and a S -terminal that is the remote /starting/ wire and we have the R terminal. Is the R terminal hot when the key is in run position or only when the key is in the start position? I want to power up the hei ,if its hot key on /key off power or should I just use the original positive power that went to the old coil from inside the cab?

Thnx ,once again denny.

If you're replacing a points ignition with an HEI, run a new 12V hot line to the HEI. The one that powered the points ignition is a resistor wire and will only deliver 6 volts when it gets heated up.

Its okay to use that circut right ?Just replace the engine side harness wire with a new wire ? The resistor wire piece is the one under the hood ,the one in the dash is normal wire correct?

I'm not sure where it starts. Maybe Denny or one of the other guys knows for sure. I've always run a new 12 ga line from the switch. If you want to swap out just the underhood wire, check voltage at the HEI after the motor has been run a while just to be sure.

Thnx Tech ,I could have chased a problem like that all over the truck with new parts and still got nowhere!!!I will put that on the check list ,to make sure on the voltage.Which post on the switch would you hook the Hei power up to?

this is '67-'72 but should get you close. this is under hood wiring.

what I did on my wifes 68 mustang was to take the resister wire and used it to fire the 12volt relay and that was wired and fuse to the hot wire off the battery. been working that way for a couple of years know and I do run the 289 ford motor on a HEI unit through the ford electronic distributor and a bosh coil. Just a thought. Ed ke6bnl

on my dads '72 C10, he used an unfused ign on part of the fuse box, it had a male spade on it, he just hooked a female spade with 12ga wire on it, to the HEI, worked perfectly

....Yes mine has that terminal on the fuse box and is marked unfused ignition,I will use that to power up the Hei! I am using the old #4 connection on the regulator {new 1 wire alt now} That used to be the field wire to power on/off the relays for the fan and fuel pump .
The relays should be key on/off power ,along with the Hei. Thats the plan anyway.

Thnx Denny !!I looked at my fuse box and discovered it had that connector after reading your post .That took care of the last of the new wires...thnx ,I appreciate all the help. Here is the updated version of the schematic and the old one. Everything look good here or ?
