1995 XP Not Charging

[jdp6000]

I have a 1995 XP. Started acting up last week. It drained the battery while operating it. I charged the battery and made sure it was good. I installed the battery again. I started the machine. Volts before start up were 12.50. I put the meter on the battery while the machine was running noticed volts drop to 12.30 range. I gave it gas volts continued to drop. I don't thing the batter is charging. I have read hear that it could be a number of things from as simple as a fuse maybe a retifier or something else?

Has anyone had this problem? What resolved it?

haven't had this problem, but the rectifier, once ski is running, should produce 14v or more at battery.....

the rectifier is the most likely culprit-the cheapest-and the easiest to replace. i would start with that.

Here is somw information on the charging system;
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.

I hope this helps.

Thanks guys!!

I guess I'll start with the rectifier. I can't get over 12.3 volts at 5000 rpm. I get a bounce between 5.5 and 12.3. Would I get anything if it was the fuse or fuses? I'll check them first I guess.Rectifier is only $75.

Fuses........

Yes, make sure you check the battery fuse(s) first. A blown fuse will give you the same results.........no charging capacity. If the fuse(s), (some models have 2, 15 amp fuses) are o.k., then you will need to change the rectifier as stated in the above posts........:cheers:

Thanks guys. It was the rectifier. Easy fix with the help I received here. Great site!!!
