I changed the ignition switch last night and the outcome has changed again.
The Gen light has changed from full on, to dimly Glowing.
I put back the old ignition switch and the Gen light just glows as with the new switch.
I plan to do voltage test today on the regulator again to get a baseline. Jim has shown me a good Flow Chart to do testing
The regulator is working as the alternator is putting out 14.32 volts and the battery is at 14.13 volts at idle.
The regulator is a NAPA replacement and it may be the problem child. The 67 Pontiac charging circuit file shows a flow chart that Jim posted on checking the GEN Light, I plan to do this again to recheck all items.
I replaced:
Alternator Regulator Regulator Cap Alternator plug (2 wires) Ignition switch Circuit membrane on back of Speedo Cluster.
Back to square one! At least I have parts to test with.
