65 dart not charging with new alternator

IIRC the dual field required a hot ignition to one field and a ground to the second for full boogie output. There were a few round backs that had isolated fields, maybe the first year of the electronic voltage regulator? The old regulators were duty switched with points, on-off-on-off to regulate an average of 14.5V or whatever it was designed to run on. the new electronic regulators used a variable resistance ground to output a constant 14.5V (or whatever they were designed to) to work the new electronic ignition. The square backs were modular in the diodes could be serviced without pressing anything out. If you had a squareback in there and it was charging, you need another isolated field alternator (square or late round) and match it up wire for wire. You may just need a brush or 2 in your old squareback. they are $2.99 a set at a better auto parts store and about 5 minutes of work. And DITTO on testing the 'rebuilt' alternator you buy at a parts store, Many rebuilds wont even pass the machines test procedure. If you were closer to Tustin, Id give you one (oops, I gave them away already)
