Help please: I have a 2004 660 Rhino: when it gets hot, and dies, I have one heck of a time getting it re-started. It acts as if it completely drains the battery. Most of the time I have to jump start it. I replaced the fuel pump with a higher flow pump per a suggestion from another forum user.
Could it be the "stater"? Any suggestions would be greatly appreciated.

Are you using a volt-meter to test the battery and charging system...???

When it's shut off...if the battery is good is should read at least 12.7 volts...if you charge it up closer to 13V and it drops below 12.7 while cranking odds are the battery is toast...

When you rev the motor if the stator and voltage regulator are working properly it should charge to something close to 14v...

If you voltage regulator is toast the battery will not charge...it could be the stator and those are NOT cheap so I hope that is not it...

What CDI do you have...if you battery voltage is getting drained due to not being charged some cdi units will not crank the motor...

Also you should consider getting a pc925 battery...

I posted this picture even tho I don't sell batteries because people are always asking if this battery fits okay...

It would seem to me that if the battery was good, getting and holding a charge...jumping it would not help...

This may seem obvious, but have you checked all of your electrical connections to everything to make sure nothing is lose and causing a short? Offroad vehicles have a tenancy to loosen things up unexpectedly.

Two separate things to check.... the starter may be dragging way bad when it gets heated up by the engine....and even tho the voltage is proper, the battery could be so marginal capacity_wise that it could not have enough reserve to crank, maybe if you have a stereo amp, lights on while driving would actually be draining it faster than the charging system tries to charge your marginal battery

And by all means, a combination of these two issues could definately be the problem .....Lance
