Hello everyone. As some of you know I'm bringing a 86 1100 back to life. Last night I had to remove the left side CC cover to get to a clutch pushrod oil seal. Since the cover is off I'm going to put it in a parts washer. When I removed the Stator/Alternator I noticed a spot that had some black buildup. It has the consistency of burnt ash. This bike has been sitting for over 20 years with oil so I don't know if that what I'm seeing.
I have continuity between all 3 wires. There is resistance between 2 of them. The meter bounces around and doesn't really settle on a value. Since the Stator/Alternatoris on the bench I don't think I can test each wire to ground. Does anyone know if I can touch the Stator to the bike and test that way?
For some reason I can only upload 1 photo. I'll try and upload more later.
To measure each wire to ground all you have to do is attach a meter lead to the steel part of the stater unit. That will be grounded when reinstalled. Double check all you resistance readings between wires, they should all be very low and steady. One manual shows .3 to .5 ohms resistance. Short your meter leads together first to see how low your meter will get to actual zero. Then test each wire to each other.
If you look at the last page, one of the tests would be "resistance between leads of the stator." If any one of the readings is NOT between .5 and 2 Ohms, your stator is faulty.
Well, it looks like I'm in the market for a new stator. Any suggestions on which one to get would be very helpful. I haven't ridden the bike yet so I'm not looking to put the top of the line parts in quite yet. I just want to get it going and ride it around and if everything checks out then start putting money into it. I love tinkering with bikes so if I have to upgrade to a better stator down the road I'm fine with that.
Well I bought one of the cheepy ones off Amazon and installed it over the weekend. It's definitely less quality but it doesn't look bad. There's no coating over the coils. They're all exposed. The wire coming off of it is way too short to reach the factory plug on the rear fender. Not a big deal I just soldered in new wires. The plug that came on it was also the wrong side. It was the male end and the factory one is the female end. Again not a huge deal since I had to solder new wire on it. I just changed the plug to the correct female one. Which is supplied.
Haven't fired the bike up yet but I thought I'd give an update. I still need to put new seals on the slave cylinder and bleed the lines. I'll post my findings on the output of the stator when I fire it up.
I wouldn't worry if it looks there is no insulation over the coils as the original. They have to have varnish on them to insulate them. Even the expensive one looks bare.
Stator is I stalled and bike is running. The oil leak that I removed the cover for is fixed! Yay!
I was taking readings at the battery at idle and I'm getting 14.6v at idle and about the same when reved up. Should I be getting less than 14v at idle? Or is this what a new Stator puts out?
