I am restoring a 65 and bought a HEI distributor. I have the coil line however I do not think it is large enough to connect tot he new HEI. I looked under the dash and am trying to figure out where i can get 12v power for the distributor. Any ideas??thanks
most people when up grading to a HEI.. install a load dropping relay below the starter solenoid.. hooked to the existing wire on the I terminal of the starter relay above.. the push on coil wire is insulated.. as it is not used to power the coil but its is still hooking the IGN 1 circuit to the bypass circuit on the I terminal of the starter relay...now that i have confused you..pin 30 of the relay to the battery side of the starter solenoid.. pin 85 to ground.pin 86 to the wire on the I terminal... still connected to the I terminal..87A to the HEI power connection...this configuration will give you full battery voltage to the HEI when the key is in the run or the crank position.. use a 30 amp relay.. a water proof version would be better.. there are a lot of cars in the junk yard where you can get one with a mounting tab and some wire already attached..
the junk yard is good for getting parts like that, check the GM fwd cars full size for the water proof relays mounted on the top of the fire walls, and the Gm pickups have a water proof fuse holder(for fuel pump) under a plastic cover passanger side that has a tab for mounding to the firewall.
Thanks for the info. It was just what I was looking for. I hooked all this up today and it started right off and idled great. Though I tried it again 10 mins. later and the rpm seemed to be higher at idle this time. Then about 30 mins. later it would not start at all unless I bypassed the relay. Any ideas?
got pictures of where you hooked it up..got part numbers from the relay... some relays are not designed for the amount of current thats passing across the contacts...some relays are also INTERMITTENT duty... what type of relay did you use... GOT pictures???
