83 1100A Stator testing

Post by taatich » Mon Oct 11, 2010 2:18 pm



I'm a novice so please bear with me. I separated the connection of the 3 yellow wires from stator to rectifier/regulator. I tested each phase to ground and got infinity or 1 on my meter. I think that is good. I then started her up and at 3k+ rpm I tested each phase to the other phases and got 0 zero VAC on all three. Has anyone had these results? I would think that I would have at least gotten minimal voltage readings from at least 1 phase. Also, should I take a resistance reading from phase to phase? Thanks.

Measure on the side of the connector leading to the stator (obviously). The first set of readings should be with the engine STOPPED.

Measure from each yellow lead to ground - you should have no measurable resistance, as you noted.
Measure from each yellow lead to each of the other two yellow leads - you should show continuity or very low resistance.

Next, start the motorcycle and hold the bike at around 3500 RPM.

Measure the AC volts from each yellow lead to each of the other two yellow leads - you should show around 48 VAC on every pair. Careful, as you're dealing with enough power to give you a serious jolt if you touch it!

Make sure when you're measuring the stator leads while the engine is running, that your meter is set for AC - if it's on DC, it will read zero, or fluctuate near zero.

You are 100% correct WingAdmin.
I had the DMM set wrong. Retested and the phases tested @ 65, 65, 64 VAC.
So I guess my stator is working fine. I charge the battery with a Tender Jr.
every night. I'm almost afraid to not charge it and have the battery too low to crank the starter.
I also put the DMM on ADC to see if I had current flow between the negative battery cable and the neg post on the battery and it was 0.
I guess I could still check ohms from phase to phase but I think I'm ok.
(Probably the cheap Chinese battery that can't hold the charge very well. - came from PO)
As I rode around, the digital volt meter on the dash showed 14.6v at about 3500 rpms.
At idle it dropped to about 12.6.
We'll see how it goes from here.
I plan on buying an Oddysey battery come spring. ($150 or so)
Thanks for your help!

I am working on a 1983 GL1100A with a bad stator, a guy down the road has some engines out of the frames. If i check the stators on these engines using this method, and they check out, are they sure to be working? It is a lot of work to put in a poor stator.

You can only do an ohm test if the engine doesn't run and it's taking a chance, it might show OK and still not work.

Ok i got the stator out, looks original. Looks like nothing ever apart on bike, 45000 miles. What is the original power output for stator and is there a larger replacement available?

I'm sure it is original with only 45,000 miles. The original is 300 watt, if you don't have something in mind to use the extra power don't go larger.
