I'm have trouble with my 65' elcamino's
ignition or wiring. With the car at
a idle if I turn on the headlights,
heater motor, turn signal or hit
the brakes the motor dies, it seams
to be o.k. at higher RPM's.

I put in a 135 amp alt. but no help.
I'm thinking maybe a bad ground or a
bad ignition switch.

One more peice to the puzzle is, when
first get the car I found a wire and
switch under the dash running to the
starter, at first no one has an idea
what it was for, now I'm thinking it
was to seperate the ignition from the
accessories, but the wire was disconnected
and the ignition wire was spliced.

thank for the help bob

I would try a find a wiring diagram for your car. The wiring is probably original and back then they were small wires some have probably broke or frayed in half. As for the HEI all you need is to run a 10 gage wire from your ignition to the HEI. don't use the factory resistive wire.
For a 135 amp alternator you should be using at least a 8 gage wire but a 6 would be better. If you car would actually use 135 amps it would melt the wires from the factory.
Check out this months Car Craft, there is an article on wiring.

Start with a voltmeter on your system. Measure the voltage at idle and at a revved up speed. (Definitely your situation is a bit weird.) Do this measuremnent when you go thru the stuff that shuts your car down. Work back to the battery to find the problem. Even if your alternator is not working, the battery should carry it on for quite some time.

Hi bob
Thanks for the reply, I found the problem
in the resister wire. Someone tried
to splice it long enough to sell the
car. I guess it worked. A new wire and
I'm back on the road. thanks again
