REFLECTOR: RG Up and down shut0ff

[Scott Baker]

Hi Jerry,
Since the pump continues to operate at the end of both the UP and DOWN 
cycle, I'm thinking your hydraulic pressure switches are okay.  It's not 
probable that both switches failed at the same time.
If you don't see leaking fluid, what you describe speaks to an internal 
leak - either a torn seal in one of the rams, or possibly a fault with 
the dump valve seal.  There is also the possibility of a faulty check 
valve or trash inside the hydraulic pump that is causing it to bypass.
Begin troubleshooting by plugging the outlets from the pump.  If the 
pump cycles normally, move on to isolating each of the cylinders - one 
at a time.  You will need some caps to plug the hydraulic lines as you 
go about isolating the problem.
Good Luck!
Scott B.
