wheel scrubber again

[Jimmy Buffett]

My wheel scrubber is kicking my butt this year. It seems like it's one thing after another. Mine will wash 20 cars in a row just fine then the scrubbers will not retract and just sit there. So far I have been lucky and noone has driven away with the scrubbers extended. I can't make it act up using the test function and the only code that I get is a "10" which is the prox. I replaced the mac valve but that is all I can think of as the problem. The cylinders are fine so I keep going back to the mac valve. Anybody have any suggestions?
Thanks

What kind of machine do you have?

Yeah. Sorry. It's a soft gloss.

when replacing the mac valve did you replace the whole piece including the wiring? alot of operators(not you) will just remove the 2 screws holding the 2 pieces together and replace just the body without replacing the electrical wires and that is where it's critical also have you replaced the proxes for the wheel scrubs?

 

[Jimmy Buffett]

yes I did replace the whole thing and I have replaced at least 1 of the prox switches, maybe both. I did 1 myself but can't remember if the tech did the other one. I had him look at it a few weeks ago. He couldn't find anything and then it was fine for a couple of weeks. After that it started again. Sometimes it will do 20 cars between faults and sometimes 120. I live in fear of someone driving out with both scrubbers extended.

So the SoftGloss Stops when it does this and you get a Code 10? or does it continue washing?

 

[Jimmy Buffett]

No it stops and the top brush is usually down.

Jimmy-

Disable the wheel scrubs for tonight and I will talk with Ray Weddell (Service Manager) at Ryko Mfg tomorrow morning and I will shoot you an e-mail as soon as I have an answer but disable the wheel scrubs to keep you up and running and making money.

 

[Jimmy Buffett]

Thanks. Thats what I did. They have been off a lot lately.

Jimmy-

Just talked to Ryko and they didn't provide any more info then you and I already know, but one thing he did point out is to check the exhaust valve for the retract mac valve also he said to bump up the air pressure a little for both sides.

 

[Jimmy Buffett]

Thanks, I will. I'm going out of town for a week. As much as I hate to I'm going to leave them off while I'm gone.
