I suppose I was the first sucker here.
I saw them on ebay and went to their web site. SEM Direct Replacement Stator Husaberg 1999-2003, Husvarna & Vertimati (some models) European Models - English | RMSTATOR.COM
They give the resistance values for the stator.
Wire to wire resistance:
Alternator: = 0.4ohms +/-20%
Pickup: = 30ohms =+/-20%
Source: 1295ohms =+/-20%
Now that 1295 ohm figure concerned me. I contacted them and told them that the OEM needs to be ~3000 ohm. Is their's going to work? They replied with a standard "with our improved engineering, blah blah blah, it will work great.
They had a 15% off deal for Canada's Boxing day so I decided to buy one. I thought I would then have the SEM rewound, and have a good spare.
When it arrived the box says "Made in China" right on it. I know most everything is made in China now, I guess I just thought that maybe a stator company would wind their own.
First off I noticed that there are many more arms, or bobbins on their stator. On the charge side it has 6 instead of the 4 on the SEM, and nearly 2 to 1 for the alternator side.
As Taffy said there is no timing mark on it. I lined it up with the old one and got a close idea where it should be. I installed it, and tried to fire it up. On the starter, it would pop and backfire but not start. Kicking it, it would kickback violently and about launch me. I did get it to start, but VERY rough running, lots of backfiring. Couldn't rev it 1/4 throttle without it backfiring so bad it would start to die. I tried the full range of adjustment and it never got any better.
I have a timing light, but it is not adjustable, so finding the mark in the little window didn't work. It was way off.
It damaged my engine from all the kickbacks. The sprague clutch went from working great, to now just spinning most of the time. Will have to pull the clover one more time now!
I put the SEM back in it, and it fired right up and just purrs. No backfiring, no kickbacks, it just starts right up and runs smooth.
RMstator had me return it to them to check out, but I am doubtful it is going to work. When I get it back I will give it one chance. If I get the same backfiring monster, it is going back for a refund.
I asked them about the Electrex, which looks identical to theirs. (Both made in the same shop in China I am sure) Electrex shows a 98 and earlier stator with roughly the same resistance as this one. But Electrex does have one for 99-2003 that looks identical, but seems to have the right resistance. They had no comment on that.
I'll reply again once I get it back and see how it all shakes out.
