Starter or something else

[Clivingston]

Alright starter experts... Pulled the suspected starter and the post where the positive goes moves around... Gonna say that's not suppose to as my other one does not? About to take it apart. I tried to start it before it I took off and it spun up a few seconds then stopped.

Looks like you found the problem with that starter. Hopefully Minnetonka got you fixed up.

What I would do is, get a brush kit and clean that stater up. It is pretty well junk, but the brush kit is cheap and it may buy you time. Get the OEM from Tonka and have it ready to go. The armature of your starter is all but toast...

Which part is the armature?

Riddle me this batman... Got my brushes in today and go to install them and it won't work. It's shorted to ground. My positive and ground are shorted. After about an hour of troubleshooting I can't seem to figure out why. Here test results.
1. Fully assembles=short to ground.
2. Took brushes out and left just armature and frame = no short.
3. Brushes in brush frame out on bench no short. The positive is isolated from the brush frame as it should stars in sm
4. Once the brush frame goes in and that brush touches the armature it all shorts together. With or with out the positive brush in.
Is the armature bad? Need some help please

As I said earlier, your armature looks wiped out.

You can test the armature using the OHMS/CONTINUITY option on a DVOM. I'll look and see if I can find you test on it.

I looked up an armeture test where it said to test the connection between the computator 180 out. I get a dead short no matter how I put the leads. Each bar is dead short no matter where I put it.

Sorry for the repeat. Lost track of my thoughts. I put my meter 180 from each other on the part where the brushes touch... Short... 90 out.. Short... Side by side short.

Then it is shorted,,, Which means the armature is junk.

Save your brush kit and get the OEM from Minnetonk4me.

Normally when the copper color is gone, there is a dead short from winding to winding. Once this happens, they will not last long.

For some reason, Starters are just one of the MUST be OEM things on Seadoo's. Anything else just seems to fail prematurely.

 

[Clivingston]

are all 787 starters the same?

 

[racerxxx]

They are, with the exception of there are 8 and 9 tooth. Either will work.

Thank you sir
