Generator Info

I’m using a 6V (or 12V) generator and a voltage regulator. What’s this about connecting two wires?

To make sure you have the proper polarity after connecting a new generator with the regulator you must *momentarily* connect a jumper lead between the generator (GEN) terminal and the (BAT) terminal of the regulator *BEFORE* starting the engine. The momentary surge of current (via the jumper) will correctly polarize the generator. This problem does not exist with an alternator, but only generators. Failure to properly polarize the system will result in burned contact points in the regulator and consequently no charging.

I’ve installed a one-wire alternator in place of my generator, but I really have to get the rpm’s up before it will begin to charge. I used the original pulley from the old generator. What is the problem?

You must spin the alternator faster than the generator in order to get it up to correct output at idle. Thus, a smaller pulley is required. I needed a 5/8″ groove pulley and found one at 5th Ave Auto Parts in Clay Center, KS (913) 632-3450. It was a bit pricey, maybe you could do better at your local wrecking yard. Once the smaller pulley was installed, I get full charge at idle.
