Thread: Powervalve help
01-26-2007, 01:07 PM #1
Guys i have been working in the back of my 04 Gpr today, had the exhaust out etc
Anyway when i put it all back and run the motor all was fine except i DO NOT HEAR the POWERVALVES extend and retract 30 seconds after switching off . They do extent and retract imediately after switch off ( but not 30 sec later)
It states in the Worshop manual that it should
WHERE SHOULD I LOOK

If there was a problem with the motor or connections, the check engine light would come on after you start it up.
Fire it up and let it idle for a minute or two. Then dont pull the lanyard, but push the stop button instead. Wait a few moments and you should hear the valves cycle off and on.

Dont have any warning lights as i have taken my clocks off
Do you know if this circuit is connect to the bilge pump,
I can hear a ticking noizes in the engine compartment when enging is off ie a Timer, but no 2nd pulse on the pwervales, when you pull the lanyard
THE VALES Move manually and you can see the shafts move when it hits some revs, i do hear a very quick cyle when the engine is turned off
HAVE TRIED PULLING THE LANYARD AND REDSWITCH

No the bilge is seperate. If you pull the lanyard the valves wont cycle (if I remember correctly)
You may be ok. Hard to tell without a cluster tho
You can pull the PV motor boot back and pin the throttle. You should see it move then.

The PV motors on these skis are notorious for crapping out. If you remove the motor and separate the housing halves, you'll notice that it is not sealed very well at all from the factory. The circuit board will have all kind of corrosion on it, particularly where the power and ground wires solder to the board.
If you don't intend to go gas valves, I'd suggest sealing the perimeter of the housing with silicone. Lots of us have found out the hard way that this is required.
