2 Field Alternator Question

2 field alternator, gutted ballast and spiced the wires thru it, just to appear stock and made it easier, grounded one field to case, ran a ground wire from there on the alternator to the vr to the battery.

Electronic VR part # 35-300 on ebay, looks identical to stock and connects the same way.

Wouldn't keep a charge until I replaced the stock vr.

Bypassed ammeter, added volt gauge, msd, etc.
