Blowing Fuses, GTX Limited

[Flyin Bryan]

I have a 1998 GTX Limited. We were on the lake this weekend when it suddenly shut off, No Power. I found the 15 amp fuse in the front blown, replaced it, started it up and drove it about 100 feet before it died again. This time I found the 15 amp fuse in the rear blown. Replaced the fuse, started it up and got about 30 feet before it blew again. Another thing that i noticed was the 12 v low alarm. From reading a couple of threads, it looks like it may be the rectifier. Is this built into the MPEM? Is there any way to repair it?

Thanks,
Bryan

had the same problem with a 99 gsx.. turns out to be a bad stator..

starter

sounds alot like my problem with my buds 98 limited. Did MPEM with no luck.Starter is what im gonna do today.

I appreciate the help. How do I go about testing the stator?

 

[Flyin Bryan]

Starter or stator? Thanks for your help.

STATOR, its inside the side cover

Ok...the stator puts out volts. If the fuse blows that means the stator is working. Check the battery with a volt meter when it's running (for the short time it runs) if it shows 13-14.5 volts It's the rectifier, if it reads higher 16 or high volts it's the voltage regulator. In any case change both.

Ok guys, the starter will not blow either fuse in the system. Here is some information on the charging system, where the problem is. When the engine is running, set your voltmeter for 20 VDC and put the leads on the correct terminal posts. With the engine running, you should be reading anywhere from 14.5 to 14.8 VDC. (typically this test is done at 5,000 rpms) This tells you your charging circuit is good. If the voltage is higher, the regulator is bad. If you’re not showing a charge and you've replaced the rectifier, you may want to do a test on the Magneto/stator/charging coil. If you’re not a premium member and you don't have access to a manual, this test will be hard to do without it. There are 2 fuses that protect the charging system. Check the 15 amp fuse in the MPEM and the 15 amp fuse between the solenoid and the MPEM.

The magneto and stator create un-regulated AC current. The "rectifier" converts that AC to DC current and the regulator maintains the current between 14 to 14.5 volts DC for the engines operation and charging circuit.

Thanks for the advice. Is the rectifier built into the MPEM? Where can I find the voltage regulator?

the rectifier is built into the mpem, which makes replacemnt very expensive

Stuck

I was out on the lake when i noiced the 12v low on dash. a little later the 1997 GSX died no power at all. upon inspection i noticed that the black ground from the rectier to battery ground was broke, then noticed the 15 amp fuse below rectifier was blown. i fixed both and i still have no power at all. the battery was checked and looked good. any help would be great

1998 gtx ltd 951 blowing fuses

Hi all,
My gtx ltd is doing the same,(blowing both 15a fuses)
any idea of what i should expect to pay for the repair at the dealer?
or is it a diy repair?
many thanks in advance for advice
