OK, some excellent discussion here!
After reading some of this discussion I decided to fire up the truck again and note the result.
I have carefully rewired the alternator with new connections, just as it has been wired and driven for several years.
This is currently an external regulator GM alternator.
This may not be the best conversion.
I now have some concern that the regulator may not be functioning properly.
At fast idle the Amp gauge shows a charge, just past half-way to the full mark, with a light flutter.
If the RPM is increased the Amp gauge flutters hard, between midway to max charge.
My analog volt meter reads 13.75V at idle, pegs at 16V off idle.
I need to find my digital meter to read the full charge rate.
I am going to charge the battery again to ensure it has a full charge and repeat this test with the digital meter.
I may have to pull the dash cluster again to confirm how the loads are connected to the Amp gauge.
What I read here is that the only load is to the battery, with all other draws taken from the ignition switch.
I have to note, that does not sound like what I observed when I took the gauge cluster out to repair the wiring.
In any case I think I will limit my alternator to no more than about 70A rated, and will probably put the circuit breaker between the alternator and Amp gauge.
The good news is that the electric fan and choke both work very well.
Only one wire left for brake lights to work!
