Hello Mike,
Thank you for providing the part number for the breaker, I will see if I can find one at a reasonable price... As for the generator having 3 brushes, I have no idea... Will it be visible by removing the band? If I understand Jerry correctly, the Delco 948-R may or may not have a third brush? The only clear thing is that if it has a third brush, the adjustment must be done at fast idle with a fully charged battery..
It seems that whether at idle or 2000 rpm, I don't see more than 6.13 volts out of it... I just started the truck after 2 days and following a short drive the battery is at 6.13 volts at rest...A fully charged battery should probably be in the 6.30 to 6.50 volts I imagine?
Another curiosity is that the needle on the gauge never indicates a charge (or it is so slight it is not visible) but seems to indicate a discharge very well, especially with the headlights on... I wish I could adjust it to give at least 6.50 or 6.75 volts... The odd thing is that without using any lights the truck starts right up every time. With a system barely charging over 6 volts, it seems that it would be an issue over time... Only after a long run on the 4th of July parade (5 mph) while using the parking lights, I had a problem where the truck would not crank even after a 15 minute run at high speed (35 mph!)... Luckily, I had a slight slope and I was able to push the beast and get it started to get home. After that I charged the battery overnight and have not had any problems even using the headlights on two occasions at night for 15 minutes each time; yet I still have to adjust/resolve the charging system...It is clear that it is not where it should be, just barely functioning...
