voltage regulator

[JohnZepka]

Can anyone tell me why I keep frying the power wire coming out of my voltage regulator?  Replaced the regulator twice and I burn this wire right away.  The wire goes from the regulator to the bulkhead connection to the ignition switch.  66 charger.

If you disconnect the wire from the regulator to the alternator does it still burn?

[JohnZepka]

If I disconnect the wire from the alt, the one that goes to the regulator everythings fine except I get no charge.  So no it doesn't burn then, does that mean something?

Please help, I'm desperate.  I cannot get this right.  I connected everything back up the way it should be after replacing the burned up wires and I get smoke from the new v-regulator with just the ignition on.  Now they say it might be just burning off some crap and that might be normal for a new regulator.  I got 12volts from my threaded stud on my alt but nothing from my field connections even if  I change the ground from field to field.  Now I have no charge when everythings hooked up.  Both the alt and the regulator are new.  What am I missing.  I feel retarded.  I'm going to have the alt tested tomorrow and start all over.  Could this be an iginition switch problem or something else?

You say the car is a '66 but you also say field connections and say you changed the wire "from field to field". A '66 should have only a single field spade terminal on the alternator.

Have the alternator and regulator been upgraded to '70 and later?

I grounded the other field on the alt.  All the info I got said it was ok to do so. The regulator is aftermarket for a 66.
