Last summer, my alternator in my 71TR6 went haywire everytime the engine compartment heated up on hot days. This was evidenced by the ammeter pegging on the charge side of the dial after driving for a while. Turning on the headlights and the blower seemed to keep the charge current from cooking my battery but, this is not a good long term solution. I may be wrong but I suspect it is the voltage regulator that is the culprit since transistors are known to go into left field when they heat up.
The alternator is a Lucas 16ACR with an internal voltage regulator that is is correct for the 1971 so I really don't want to swap it out for a more powerful Bosch or GM retrofit. As a result, this past weekend I opened up the alternator. They certainly didn't make things easy since there are no markings on the regulator other then "Motortronic" and "Made in England". Further, it is a 3 wire regulator that I haven't been able to find any reference materials on.
My questions to the forum are:
1) Does anyone have a part number & source for a 3 wire voltage regulator for the Lucas 16ACR?
2) If no sources are available for the 3 wire, will a 4 wire work? If so, how does it get wired into the alternator? (photos are welcome if available)
3) Is it worthwhile to replace the diode pack while I'm in there as well?
As always, I appreciate any and all comments!
