Customer Question
I have a arctic...

I have a arctic cat 650 h1. I was having charging issues, so I tested the stator for ac voltage which it has to specs. I put a new battery in also. So I got a new regulator/rectifier, started atv, multi meter showed charging 14/14.5 volts, all good. Then a few days later cranked over hard, got it started, checked for charging and it was, but after it runs for a bit, 10/15 minutes, it stops charging, voltage will drop down almost immediately to about 13/13.5 volts and keep going down from there. I've checked every plug, every wire, every thing. I even checked the stator again when this happens, and it is still putting out the correct account voltage. If I leave the ATV running it will start charging again, timing is random as to when. If I shut it off for a bit and restart it, it will usually be charging again for awhile, then repeat what I already described!! I'm at a loss. Is the new regulator faulty?? It does get fairly warm, is it thermally protected some how??? Any help would be extremely appreciated!!! Sorry for the long explaination.

Mechanic's Assistant: Have you checked all the fuses? Do you have a wiring diagram?

Yes

Mechanic's Assistant: What year is your 650?

2007

Mechanic's Assistant: Are you fixing your 650 yourself? What have you tried so far?

Yes

Does battery go dead? The charging rate will go down as the battery is charged and the voltage gets to a safe level and will go up again when the battery voltage drops or more electrical load is applied. It will not stay at 14/15 volts. ??

The voltage will stay low even if I put a full load on it, four head lights and tail light. The battery will not go completely dead, but low enough the motor cranks slow/hard.

oK> I think you are chasing a problem that does not exist. Yo could have a starter or cable problem, making the unit hard to start. ut from all I see from your description, the charging system is working as intended.
