RE: [Chrysler300] Voltage regulating

Hi Larry..went around with this a few times…there are replacement ones with a red wire hanging out, electronic “replacement” from China I think. But private labeled many ways. They are pure junk. They fail on, just as you say. Boils the battery. After much pain on this, I found that Standard Motor Parts has, or better had, a higher line, like the old Blue streak parts, that looks like the mechanical one, black metal box with two metal terminals, electronic , that work hassle free. No flicker. SMP makes or resells the cheap one, too. Good one is 2x the bucks. But still cheap.

I had so much trouble with the one with wire hanging out, changed 3-4 x, that I found an old mechanical one from a junkyard that worked fine for a few years before finding the one I describe. The mechanical ones cause the needle dance and flicker..but so what..it works. I wish I had more specifics for you on the good one .

FYI, The older one wire alternator has one terminal of field factory grounded, you can use a two wire two brush alternator in an older MOPAR by grounding one of the two wire alternator terminals.--the one wire from regulator in old design puts + 12V regulated for charge rate on the alternator , the +12 is derived from the ignition terminal on the box—one wire MOPAR alternator used at least to 67, maybe later; (not like one wire term, as used today) . which terminal is which is critical..you blow them up if reversed. The original terminals had different ends to prevent that, but they often break off, resulting in wires under screws .

Good luck..! John

Back from Sparks NV and the Inc's spring meet. The alternator is showing a constant charge after miles of highway driving. NAPA only has the mechanical regular for the 1963 300 Touring 8 (my new name for Sport) and the existing VR is an electronic type I learned about from Hertog. Anybody know a part number for those small aluminum types that don't make the headlights flicker at night?
