stator replacement

Hey guys been a while I have a 83 kz750twin belt I had the carbs cleaned and tune up new battery was riding great for 2 days till I stopped at a 7 11 the it wouldn't start again I noticed the headlights were dimmed almost off the battery was dead took to mechanic he checked it and told me stator was bad my question is can I do this my self and how or should I have the mechanic do it I have a stator I got from eBay any advice will help

Here's where I would start. I would buy the Kawasaki Service Manual. Be sure to get one for your exact year/model (KZ750-K1 ?) as there are differences. I would then read up on the charging system. The manual will show how to test the various components of the charging system. I perform these diagnostics just to make SURE the stator is the problem rather than the regulator/rectifier or something else. Once I was absolutely certain which component needed to be replaced, I would read the replacement procedure in the manual to see if I felt comfortable performing the task.

I see you already bought a stator based on the mechanic's diagnosis, and that may very well be the part that has failed. However, I would still run the tests in the manual first to be positive (they should not be difficult) so I didn't replace a part that was working fine and still need to replace another part. It is not outside the realm of possibilities that you don't need to replace any parts at all, because the problem could even be a bad wire or faulty connection. The diagnostic tests in the manual should help you pinpoint the problem. Once you do, and assuming it's the stator, you can see what's involved in replacing it and make an informed decision as to whether or not you have the skills to do it. Ed

Also, if you could remove the stator cover and take a picture of the (post if, of course) it is pretty easy to see if a stator has failed at that level. Cooked stators tend to turn black. And of course, do everything ed has suggested as well.

Will do the mechanic tested the wires going from the stator to the rectifier and he showed me that the stators were grounded out something about 3 posts so I went by that

the most common problem is with the 3 wires comming out of the alternater
the ones that run up right in front of the output shaft
they always ground out in this area
i highly doubt you need a new stator never take your bike back to this guy until you know for yourself
reading a book is required to run a old bike
good luck
ps its usually the black wire that faults to ground
ive done this repair over and over again i love it
""it dont run and hasnt for years its your for 500 bucks if ya want it""
10 minutes later im going by at 130 mph on a bike with 12000 miles on it

The 83 750 twin only has two wires from the alternator.

If you lean the bike against something on the right side, you can do the following without draining the oil.

Remove left side foot peg.
Remove gear shifter.
Remove sprocket cover,
Remove generator/alternator cover.
Stator is bolted to the inside of the generator/alternator cover.

The first thing I'd do is measure the resistance between the two wires going to the alternator, and then measure the resistance between each wire and ground. If you have 2-3 ohms resistance between the two wires, and infinite resistance between each of the two wires and ground, the stator is good.

Would it be feasible to do the ohm tests without removing the cover, assuming that either the bullet connectors or the 3P connector isn't hidden underneath the cover?





Good Fortune!

Yes, check under the cover first. It may just be broken wires, and not a bad stator. You may be able to splice them if there is enough there to work with.
