My ‘47 3100 AD finally has its new cluster gauge installed and wired correctly thanks to the helpful suggestions here. The problem remained that the ammeter was still always charging! Something was still wrong!
Went back and fully charged the battery and checked it for load and draw when running. Battery ok. Next the generator was checked for output, draw with lights/no lights. Appeared normal. To reassure my self I had it bench tested. Was ok. After I mentioned the next step, the voltage regulator, the technician said he needed the generator and VR together for the test. Next day he tested both and said the VR was the problem.
So I’ve ordered a new VR- not cheap but obviously necessary. Hopefully the malfunctioning VR was causing my ammeter to always show Charge. Hope I didn’t fry the ammeter in the process!
I’m reading here but can’t find an answer to: “ will I have to polarize the VR or is it a simple install and connect the generator and VR?” I am not the sharpest knife in the drawer with elect. stuffing.
