Serial #515818969 Grapple was working fine for 20 minutes or so when it slowly started to drop in open position. Eventually it wouldn't open at all. I can get it to open partially if I hit the switch rapidly, but as soon as I stop it drops down to closed position. All other hydraulic movements function well (boom up, down, tilt, forward & reverse). I found that my fan blower pully/belt was loose and not tensioning correctly so will be replacing soon, but not sure if that could affect auxiliary power at all? Any info would be greatly appreciated, thank you.
