The car is next to impossible to start when cold. The battery has 12.5 volts. I charge the battery to a higher voltage and engine start easier. I think I need to go to a 1970 and later electronic voltage regulator to increase my voltage. Am I on the right track? What wiring has to be changed? The later electronic voltage takes a plug and my harness has spades for the stock regulator.

Some refer to this as double field alternator but in reality the others also have 2 fields but one is grounded internally. Really the alternator you have now should keep that battery charged if you aren't running with a bunch of electrical draw assesories.

Is it cranking way slower when cold & if so are the cables clean and do you have a known good newer batt to borrow to see if that speeds it up. To test a battery you would slow charge it overnight & have a parts house test it but most dont have the right load tester so the test is invalid and it's just as easy to sub one in real quick. If it is cranking good is the choke right but from your Q I'm assuming that it is a cranking speed issue. Last edited by RapidRobert; 04/22/10 06:26 PM.

And the regulator we were referring to will not work on the older style alternators. The his oem system should work fine if his battery is in good condition and the connections are clean and all grounds are good. Shouldn't need a band aide constant out put regulator on it.

Homework - Hell I was working on these things when you were more than likely in 3 corner pants or before. Constant regulators are not meant and never were recommended to be used on constant running applications, but on race applications where short term charge is needed to keep a battery fully charged A good charging system is all that is (should be) needed and that constant 'flow' regulator is not the answer. If you feel that it is then go for it.

I been useing those regulators since they came out. Never a problem. There are a few hundred Mopars around here all useing them. We must all be stupid.

Still got 10 years on you and started working on them for a living in 67. Was twisting wrenchs on cars and trucks since I stared driving and at age 10 was hauling to elevators with grain trucks and had my license just by my 13th birthday. Glad to hear that you haven't cooked a battery (yet). Never were meant for constant street use but if you want to use them go for it. Few hundred I would doubt but if you say so.

Since I posted the question I re-installed a rebuilt alternator that I had previously used. I am charging the battery and will try starting the engine tomorrow to see if I have more success. Where can I purchase the 3690732 regulator you referenced?
