They look good they are evenly spaced and are all stuck on there extremely tight, also the rotor will not turn without turning the engine, so I guess that rules those out, what else should I look for.

So I checked the output voltage directly from the stator and I was getting 3 AC volts with the old one now I'm getting 8 AC volts which explains the higher voltage at the battery, what it does not explain is why the difference? I'm starting to think maybe I got a bad stator.

I took some pics of the insides so you guys can see my setup.

Thanks

do you see the white lines in the middle of the magnet
sign of bad adherement at 8ac volt you have a seriuos promem
you should have about 20acv at idle and over 50 acv when rpm are incleased
are you check output with stator wires disconnected
check to see if stator is shorting to ground may have pinch wire in backside of stator
if still have problem you need to seek a real machanic

So does that mean they are going to come loose soon should I put some epoxy or something around them to help them hold better? Also I am checking it with it plugged in.

EDIT:

Ok I checked it with it disconnected (had to hook up to my car for it to run) and at idle I'm getting 12 VAC and at increased engine speed I'm getting 50 - 60 VAC. I found a walk through test for the stator and regulator rectifier and I'm pretty sure it failed one of the tests for the RR. Here is the link but I will post what happened here.

I attached a copy w/ my notes so you guys can see where it failed. Thanks

I would be inclined to agree that your R/R is bad.

So do you think the old stator was bad as well since it failed the resistance test? I'm figuring that maybe the stator failed and that caused the RR to fail as well, or vice versa. Either way I found one for $30 so once that comes in I'll let you guys know. Thanks again.

Can anyone who has a suzuki eiger test their RR with the part that mine failed on? I just got one today and I'm still having the same problem and it too failed that same test. I want to return it to the Ebay seller, but I want to make sure it is really bad. Thanks Guys

I would just go ahead and return it. Buying used electrical parts is always going to be a crapshoot, you never know what you are going to get. You are best off returning it sooner than later. If you do manage to find another machine to test it on, cool, but I wouldn't wait too long to return the part.

Figuring out problems like these can be difficult. Electronic ignition and EFI systems are the most difficult thing to diagnose. I hope you can get this problem licked.

Ya I guess I was hoping $30 was gong to be a good deal compared to $300 at the dealer. Sigh :(

I would never buy parts from a local dealership, an online parts dealer will typically cost around 30% less for OEM parts. I looked up the OEM rectifier assembly at three online parts dealers.

Bike Bandit - $146

Babbits Online - $129

Service Honda - $122

Ya me neither they are ridiculously over priced, oh well I am sending the one back so I guess I'll be looking into getting a different one. I'll keep you guys posted. Thanks
