    My HEI swap is almost done. Just one small problem...

    I spent the weekend finally gathering parts for the HEI swap I've been wanting to do for the last 6 months or so. Everything went in without a hitch, except when I wired it up from (what I thought was) the ignition wire.

    It was among a group of about 12 wires on a plug on the steering column that appeared to go up into the ignition switch and, I guess I wasn't paying close enough attention because as it turns out, while it was the only wire "hot" in the "start" and "run" positions and not hot in the "off" and "accessory" positions, it is only putting out about 6-8 volts.

    The first thing that popped into my head was ballast, but I cut the ballast wire off, and there should be no ballast under the dash anyway.

    So as it stands right now I have a wire (10 guage) going from this purple wire, which I thought was the ignition wire, directly to the HEI BAT+ terminal and its supplying about 6-8 volts.

    Just to make sure everything else was ok I ran a wire straight from the + post of my battery to the BAT+ terminal on the distributor and cranked her, and she fired right up.

    Does anyone know where I should be taking my 12 volts from, or why this purple wire is only supplying about 6-8 volts?

    How about using the S terminal at the starter solenoid?

    Thanks for the reply. I managed to get my HEI going though, I finally managed to figure out the wiring diagrams and found the wire that supplies the ballast under the dash and used that one. Wouldn't the S terminal only be hot during cranking though?

    You are correct. I confused the S with the R terminal.
