'78 GL1000 stator testing

Postby jacksprat54 » Mon Jul 07, 2014 12:17 pm



I'm getting a lot of conflicting info on testing my stator; in particular the resistance between the 3 yellow wires. Honda shop manual says, "check the yellow leads to the AC generator for continuity with each other"; no specified numbers. Clymers says: 1.1 ohms, significantly lower readings indicate short. Ricks motorsports says 3.5 to 4.5 ohms. I have .4 across all three. Blew a regulator for no apparent reason. Any advice is appreciated.

Resistance can vary for several different reasons. As long as you don't have an open circuit on any of the three, the windings are at least somewhat intact. You should also measure from each leg to ground - you should have an open circuit (i.e. no short to ground).

The best way to test is to switch your meter to AC volts, run the bike at around 3,000 RPM, and measure the voltage being produced across each pair of legs. You should see ~48 VAC across each pair. A significant difference on one pair (or no voltage at all) indicates a problem. Be careful, as a dangerous amount of voltage is being produced - treat it as you would a live residential 120V circuit (i.e. touch only with meter probes, not your fingers).
