hei upgrade on 82 2cycle

Derbyguy74 · 01-04-2013, 10:27 AM

Ok i need some clarification on something. Im doing the hei upgrade on my 82 marathon with 2 storke. The wiring diagram in the sticky note in the forum. The regulator shows the d- spot goes to the mounting bolt of the module and to the solenoid. Wouldn't that short the module, solenoid or regulator? I would think the d- on the regulator and the module mounting bolt would be a ground. Why does it go to a power on the solenoid? I did the conversion and still no spark. Switched the pulsar wires and still no spark. Tested the pulsar and ohms are good.
Thanks

No it would not short hei, it will provide a ground for the hei metel plate, which has to be grounded to work. The d- also grounds the regulator and start solenoid which is needed.. If you follow the d-, it goes to - on battery and the battery - is grounded to frame

You should have +12v on the "b" term. of hei ,when pedal is depressed.
you should have a pulsating 12v on term. "c" of hei when motor is cranking.
No other terminals on hei should be connected to the d-. only the mounting bolt.hope that helps.

Ok so the d- on regulator goes to mounting bolt on module and to mounting bolt on solenoid? Not to post on solenoid?
Thanks

The d- does go to the small post on solenoid, term. c on schematic. The wire color is black. The other small term on solenoid goes to the pedal start sw. and its color is red. If you havent modified the cart wiring, those stock connections to the regulator and solenoid should be ok.

The small post on solenoid is + when pedal is pushed. So power goes from small post on solenoid to d- on regulator, then why d- go to the - on battery and d- on mounting hole of module?

How many posts do you have on your solenoid? You should have 2 small posts and 2 large posts. The d- is your ground wire for the regulato,hei and solenoid, thats why it goes to the -(neg) on battery, which is grounded to your frame.

Mine has 2 large and 2 small. I will try a ground wire to it. It just wasent seeming right to me to bring ground a solenoid post. If it works that could have been my problem before the upgrade.

Got it running. Was a little leary about the way the wires run but fired up as soon as i hit the gas.
Thanks a ton guys.
