    So I installed an ignitor II, a weber 32/36 progressive carb, and a super stock Accel coil. When I turn the key it fires right up. However, it doesn't want to stay on. Does this sound more like poor carb tuning rather than the ignitor unit?

    Also, when I turn the head lights off, I get shocked. I was thinking a short somewhere? And if there's a short does this mean the pertronix unit could be misfiring since it's not getting adequate voltage?

    Thanks

    Did you bypass the resistance wire?

    As to the headlight thing, could be a broken wire on your headlight switch. It doesn't take much effort to get that out and look at it. Maybe, 10 minutes to get to it, another 10 to get your dash put back together.

    I thought I had by passed It. I don't have a pink wire, or at least don't see on running to the coil from the fire wall. I only saw a hot wire ran from the key to coil and I used that. I've been looking for one but I never saw one.

    Since the wire that goes from the ignition is the resistance wire I ran mine into a relay to supply 12 volts straight from the battery. I didn't want to hack up a perfectly good wiring harness, it's only original once.

    I know pertronix makes a relay. Would that be worth investing in. I don't know anything about electrical systems

    I bought a 12 volt DC relay that switches at 6v at radio shack for like 5 dollars. Along with some 10 guage wire and some quick connect terminal crimps had the whole thing ready to go with 1 trip to radio shack and around 25 dollars.

    Then you take the wire that comes from the ignition plug it into the control side of the relay, run 12V on the 10AWG wire from the battery to 1 side of the relay switch and a 10awg wire from the other side to the coil. Ground the relay to somewhere, then turn the key and fire up the engine.

    Get this relay

    http://www.radioshack.com/product/index.jsp?productId=3020762&filterName=Type&filterValue=SPST

    Ingition wire goes to 85, 86 goes to ground, 12V+ from battery goes to 30 and wire to the coil connects at 87. (85,86,87,30 being the pin designators).

    Wire:

    Quick Connects:

    http://www.radioshack.com/product/i...Name=Cable+type&filterValue=Quick+disconnects

    get 2 packs just in case.

    Super easy modification.

    I also put in an inline 30amp fuse in front of my 40amp relay, an ignition system should pull a much smaller amperage than that but I wanted a fuse to blow before melting my relay.

    http://www.radioshack.com/product/i...ce=CAT&znt_medium=RSCOM&znt_content=CT2032234

    I think you could put in a fuse as low as 15 amps.

    And your idling problem is probably timing and carb tuning related. I know I had to drastically re-time for the Ignitor II.

    That's what I figured. I hope the radio shack here has that stuff

    That's the tough part. I luckily know where 2 are within a half mile of each other and they tend to compliment each other for what they carry. If I can't find it at one the other usually has it. Or they can get it for me. Been shopping at those 2 locations for 20 years.

    Socorro is close to Albuquerque isn't it?

    I've been to this place, http://www.yellowpages.com/albuquerque-nm/mip/electronic-parts-co-6269643?lid=216898700

    Bought some stuff for my sister there when I was visiting her, if I remember it correctly you should be able to get everything you need there. Just tell the guy you need a 12 volt 40 amp relay with a coil activated at 6 volts. Tell him what your doing and should be able to sort you out.

    Sometimes at places that are actual electronics places they will even help you get started on the project if you ask. like cut some wire lengths, put some crimps on and show you how to hook up the relay.

    Should I also buy a back up relay and fuses? Can they burn out fast?

    Optimally it would be 40 years before you needed to replace them. Your coil would probably boil and explode before you fried the relay.

    That's comforting. Ha. Another question: I have a few coils available to me. 2 axcel super stock, stock replacement, and the flamethrower III. Would one of these be better than another to use?

    Why do some people need to bypass the resitor wire and others don't? I noticed once my volts drop the car dies. I'm guessing that's from the resistor wore
