Voltage regulator 96 xp

[hantsman]

Hello,

Just got bought a cheap 1996 seadoo xp that needed a starter. Replaced the starter and it fired up and revved up like it should but battery wasn't charging. I found a blown fuse and replaced it, now the battery charges but it won't rev. Remove the fuse and it revs and won't charge. Anyone have ideas on what coukd cause this?

New fuse and disconnect the red wire from the voltage regulator. If everything is perfect it’s a bad regulator. Although it typically doesn’t blow a fuse.

 

[hantsman]

Fuse is in and disconnected the red wire and it runs fine but does not charge. Looks like I need a voltage regulator?

 

[mikidymac]

Yes. It will not charge with the red wire unplugged. Sure sounds like the regulator.

 

[hantsman]

I replaced the voltage regulator and it's still doing the same thing. Any more ideas?

 

[burtshaver2021]

If it runs fine with the voltage regulator unplugged as you mentioned then I would say you got another bad regulator

 

[hantsman]

Even a new one from Amazon?

I’m not sure if you’re joking or not, yes, definitely one from Amazon. Try one from OSD Marine or Seadoowarehouse.com or west side power sports

 

[hantsman]

I wasn't joking but I get what you're saying haha.. I'll try that

Did you check and see if the voltage regulator was working as intended with a multimeter? Its a quick and easy check. But Burt is right, electronic parts are hit and mostly miss for seadoos. Go OEM when possible.

 

[hantsman]

How do u go about checking the voltage regulator? I checked the battery with the seadoo running with and without the red wire connected.

 

[Grim]

start engine, put meter leads on the battery posts, see what the voltage is, should be mid to high 12v, then raise the RPMs, the voltage should increase into the 13V range, if you can get it to 5K RPM then it should be high 13V but not more than about 14.5V. If reading goes above that then it is bad, if reading stays in the 12V range , its bad,

Post your numbers and we can see what you have.

Correct, With the red regulator wire connected.

 

[hantsman]

I tried 3

 

[hantsman]

The battery is 12.6 volts with the machine not running.

Battery with the ski running is 12.8 volts but won't rev, red wire connected

I probed the red wire at the voltage regulator and it's 14 volts when the ski running but won't rev

Any ideas?

 

[mikidymac]

If it will rev fine with the red wire disconnected it's another bad regulator.

 

[hantsman]

I've tried 4 oem (used) and 1 new amazon. Seems unlikely they are all bad.

I’m only spit balling, never had a stator out and very little experience with them, tested the one on my ATV with some help and the manual. Tested for continuity I believe that’s what it’s called. I tested the Ohms of different combinations of wires as per the manual. I believe that test is to see if any wire is broken or shorting out against something. And then I tested the AC volts coming from the stator when it was running and again it tested fine so I changed the voltage regulator because my battery wasn’t charging. Anyways with that being said I wonder if it’s possible that the stator could be causing these issues? Or damaging the voltage regulators? I don’t know, just putting it out there to see what @mikidymac or @Grim think. Have you tested the stator?

 

[Grim]

Yeah, that would be some bad luck to get 5 bad regulators.
Burt I was thinking the same think but I am not well versed in troubleshooting the stator either.. For the sake of being thorough I would perform the stator checkout in the book. It may give you an idea if the stator is working correctly. I also think there is a test you can do on the regulator to see if it is within specs, I would do that too.
