1992 yamaha xj 600 seca 2

i have a 1992 yamaha xj 600 seca 2 i can charge the battery and it will run and drive fine but after about 45 mins or so you can see the lights getting dimmer and then it back fires and cuts off. so my friend told me to charge it and then take one of the battery cables off so i took of the positve while it was running and it dies and so he is sayin the stator is bad i think its something eles maybe i am wrong any ideas

 

I agree your charging system is screwed somewhere.

 

i just need help cuz the stator at the local yamaha shop is $543.99 and i really dont want to pay that much for it

 

Check on ebay Proly find a used one on there for ALOT less

 

well i found the part where its just the round peace with wires on it for like 40 bucks but is that all i am going to need or do i need the charging rotor to

 

i found it on ebay all together for 49.99 + shipping

 

Really you are guessing what might be wrong. You need a multi meter to actually measure the voltage at the battery and to see if it is charging up. The secaII is fitted with a permanent magnet rotor (so no brushes) and i would start by using the meter to measure the resistance of the stator windings against the spec in the workshop manual. i don't have a secaII but you should have "Continuity" between all 3 white wires and no circuit between the white wires and ground.

It is possible the voltage regulator has failed (More likely than the windings) - but the way to prove this is to eliminate the stator.

You haven't recently done any work around the stator area ? - another member accidentally shorted the wiring to ground when he refitted a cover.

EDIT: Don't disconnect the battery while the bike is running - you might damage the TCI/ignition system!

 

AGREED. Guessing at diagnosis and "shotgun" repairs can get expensive, especially when you guess wrong.

Markie's advice is spot-on-- you might be about to replace something that doesn't need replacing.

 

thanks for the help i am going to put a stator in it and see if that fixes it if not i will check everything with multimeter and go from there i will let you guys know what i come up with/

 

btw anyone know where i can find a windscreen for this bike looked on ebay and didnt have any.

 

Ok i got a problem i got the new stator and it only have 3 white wire with the 3 wire connector but my system has 3 whites and 1 red and it have a 4 wire plug and all the stuff i have looked at ony has 3 wires. I need help?

 

?

 

Did you take the guy's advice and check the original stator out with a meter? If it checks out, check all connections to make sure they are tight and not corroded. Make sure there are no broken wires and after eliminating all that then it is probably the regulator. As far as the extra stator you bought sounds like you got yourself a paper weight unless you can figure out the extra wire of the original.

 

Check your wiring diagram!

The Seca II has a permanent magnet alternator - the 3 white wires come from the stator and the single red goes to the battery. So there are 4 wires plugged into the regulator. I believe all US SecaIIs are like this. later Euro models had a 5th wire - a black which is just a ground.

The stator/regulator are at the bottom left of the diagram. NOTE Are you trying to connect the stator direct to the regulator by mistake? The stator connects into the loom then the loom connects to the regulator!

 

sweet i was tring to put it st8 to the regulator i feel like a idot now i bought the metter yesterday i am going to check it all before i put the stator in but if i need it its there so cant go wrong with extra parts lol. Thanks for all your help i will prolly be working on it this weekend and get it str8 and i will let you guys know.

 

So i got it in there and ran it and its only putting out like 11.98 and it was slowly going down but i reach down to touch the regulator and it was so hot it almost burnt my finger i was wondering what could be wrong is the stator bad or is the regtofire burnt up???????????????????

 

Ok so i got the ebay stator in and then i started it and reved it up and it steadily droped it was around 11.98 somthing and it just keep droping after about 20 mins the stator cover and the regulator was to hot to touch so is somthing fried or what.

 

was the battery fully charged thats whats hardest on a stator is weak or low battery. with it steadily dropping sounds like its ok. hows the regulator is it getting hot also

 

It sounds like there is a short circuit somewhere. Did you check the stator winding resistances are equal and there is no circuit between the white wires and earth?

Have you changed the regulator? I think this is more likely to fail than the stator, in fact, Yamaha changed the regulator design in later bikes.

There is a possibility the regulator has an internal fault which is causing the overheating.

Check the stator wiring again and if it is good, get a replacement regulator.

 

Ok i will try and get the regulator and see, Both the stator cover and regulator were hot.
