Reply to "Amp Gauge waving like a beauty queen in a parade"

also, given all I have is the pieces, I need a little information to help me think about this

where would be the easiest place to get connection to the wire from the altenator and the gauge. a location as close to the amp gauge would be best.

something intersting, I went and measured the ohms accross the terminials of my amp gauge and was surprised that I had 50K ohms. since it was 30+ years, not sure if it had been modified prior to me or internal corrosion. has any one every measured thiers. I was expecting a couple ohms

I found my blue regulator and when I have the chance I plan to take it apart to see what is in there

the more I watch the utube, the more it looks like a problem with the regulator (or its wiring). a couple questions
Does your speedometer "battery" lamp come on with the key to run (but engine not running)
If the "battery" lamp flickering, especially when the amp goes negative.

the scenerio I think I am see is when the amp gauge goes negative, full field is then applied via the voltage sensing relay. with full field, the amps go in positive direction till it maxs out. then the voltage sensing relay starts to "regulate" from full to no current, but never goes to the half current "double open" relay state. then the voltage relay goes to no current and the amps fall negative and the cycle starts again.

while this is what I think I see, I will need to think more and see if I can find a wiring failure that would cause when new components are installled
