Howdy Mike,
Something occured to me. With a D you have/had the additional load of a distributor and possibly converted/made the next step to electronic ignition...to go along with the load of lights?
POD's like most electronic reg's are geared towards modern sealed batteries that are happy with a higher running charge rate and limit at 7.2V compared mechanical reg's that cutout in the 6.6V range, though they do limit the amperage which is critical on sealed batteries. A 12 amp 6V PowerSonic/Werker does not like more than 3.5amps.
At any rate, original armatures can overheat, either sling the solder or short in the windings if made to work too hard, I try to balance excessive duty cycling of regulator and load on the generator by using a decent sized battery. In this case, a PowerSonic PS6100 rated at 12 amps sits vertically in a hollowed-out Exide rubber case battery. As D's have a bit more room, I've had very good luck with four applications of their PS6200 20amp battery on my other non-Vin machines.
