You may need to adjust the third brush (if your generator is the third brush type). The manual for my B describes the procedure sketchily, but it should be in your WD manual too, along with the schematic.

Thanks Phil,

I have all the AC manuals for the WD and there is no mention of set-up for a third brush or any mention of setting up the generator at all except for polarizing it. The schematics show connections from the voltage regulator on but nothing internal to the generator. I "suspect" there may be a resistor or some connection on or in the light/charging switch which is bad or hooked up wrong. It is apparently, as far as I can see, wired according to the book. There is no breakdown on what is in the circuit when the lights are on.

Sounds like the switch is bad or the wiring from the high charge terminal has a resistance in it (bad connection, broken strands, etc.) that is not allowing full current flow. I would see if the switch can be disassembled to check the contacts for burning or corrosion. If the switch is ok, I think I would check for hot spots in the wiring, indicating a bad spot. Replace whatever is getting hot to eliminate the resistance, and recover the lost charging current. Remember, you can't violate Ohm's Law. The higher the resistance, the lower the current at the same voltage.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and ... [Read Article]
