Background:
I just completed a Street Fire HEI install in my 71 El Camino. I did some homework prior to the install and recognize the requirement for increased current to the HEI unit over the stock ignition. I decided I should install a relay along with some really healthy wire (12 gauge) to be sure things would work properly. - I followed recommended procedure and tape off the yellow wire from the distributor and connected the red wire to the control pin on the relay.
Now for the problem.
Engine runs great. Starts easily and all. But the engine doesn't quit when I turn the ignition off. I measured 8V on the red wire connected to the relay. I have no idea why there is 8V on that pin. If I pull the wire from the relay the engine shuts off properly and there is no signal on the wire (without it being connected to the relay). At first I thought the relay was defective. Bought another relay but have the same results.
Anyone have a clue as to the source of the signal ?
Thanks for any ideas..
