1963 Thnderbird battery good, Alternator good, New relay ( later type works but light on dashboard comes on and stays on when motor running the only clue I had was that this started after a cold ( damp) winter Ive
It could be the voltage regulator for the alternator. Check to see if it is putting out 14.5 DCV at the battery when the engine is idling.
Yes about 14.1 when idling?
14.1 DCV is good. What happens when you rev the engine up? Does it stay 14.7 and under?
Yes stays the same even with lights on about 14.2
Charging system is working properly. There is a Instrument Cluster Voltage Regulator that is part of the charging system that may be the cause. Check it out on this sight.... https://www.carid.com/standard/instrument-cluster-voltage-regulator-mpn-vrc-604.html?singleid=64677481&url=15437710
