Have you thought about rebuilding?

I need one but mine is making so much noise I'd guess the cylinder walls aren't in very good shape.  I've not had it apart.

Can you do me a favor? I need a pic of the bakelite tower with the green diode wiring terminal at its base..
I need to see which wires go where on the diode..( I also have a '02 and they are different than the '01 or the '03's)
I have 2 terminals and 4 wires, one larger black wire with a white tag, 2 smaller black wires, and a larger white wire that also has a jumper wire to around the corner to another ground..
Our coach does not "wake up" from sleep mode on the leveling.... have been fighting this after I changed out our Thomas pump and replaced the bakelite tower with a new diode disc. I think that I didn't get the wires on the correct terminals..
 I got our pump  thru Gardener/Denver..

See if this helps.  That puppy is hard to photograph.    I'm in the coach at KOA in SanAntonio because I've got a meeting here the next few days and this sounded a lot better than the high priced hotel where the meeting is held.

ThankYOU!..
And if yours is where mine is (on a elevated shelf) Yes it is a buggar!
I might have to swap the 2 smaller black wires or put all the black wires on the post with the one with the white tag on it..

THANK YOU AGAIN!!

Isn't that the 120v version on e-bay?  Had my hopes up.
