Default Transmission keypad still energized 93 WLWB

My 93 WLWB transmission key pad is powered up or energized with ignition off, AT switch off and master switch off. The light changes location to the button pushed and beeps when I push any of the buttons. Drove 400 miles last night with no problems to Mackinaw City. I am figuring a relay somewhere is stuck. I searched the WOG forum and no answers so far.

Any help would be appreciated.

Thanks

There's a normally open 3 psi engine oil “pressure switch” (screwed into an engine oil manifold under the coach in the vicinity of the starter) which “closes” when engine oil pressure is detected. If that pressure switch fails in the "closed" or "partly closed" position it can power the Allison ECU without the key even being in the ignition. I suspect that pressure switch is your problem.

Wow. I bet that answer would be at least $500 at a dealership somewhere.

That kind of help and friendship is why I still hang around here even though I no longer own a Bluebird.

I’m still learning and you guys are great at helping people

Max.

I don't think a dealer could figure that out,without reading the WOG,

A 'failed' NO (normally open) 3 psi switch on the passenger side just aft of the starter will cause the transmission keypad to display. Mr. Wyatt helped me with that identical issue a few years back while we were attending WOG 2012 or 13. In my case just cleaning the entire manifold including the 3 psi Kysor sensor solved the problem.

My recollection is that on my 88WB, that NO 3 psi sending unit, when closed, keeps the operator from accidentally engaging the starter on the Detroit when oil pressure is present.

Hint: try cleaning the manifold / sender with a blast of brake cleaner. That area is subject to gathering grime from minor oil seepage and the cooling fan from the Detroit kicks up dust to create a mess.

Hopefully the pressure switch turns out to be what's causing Allen's ECU problem after all of that.

Thanks for the speedy reply! Well while I was looking for a safe way to get under the bus where I was parked at. The light went off. It had been on for about 6 hours after I found it still had power. We made it 400 miles home yesterday with no problems and the transmission control pad shut off just like it was supposed too when we got back. I will block it up this week and locate and clean switches. Maybe a little degreasing under there too.

This site is the best thing since sliced bread!
I appreciate all the help you all have given me and all the silent advise I have gotten from all the past posts and information to the other members. Your assistance and Randy's advise kept me from buying a project to finding the right bird for us.

Oh and the bus met and exceded all my wife's expectations. Happy wife=Happy life!

Hey,just figured out who you are!
Be careful under there,wear a big trash bag over your clothes to keep clean,just tear a hole for your head and arms.
have fun!

When I had the bus at a Clark Power Services recently, they told me if they get stuck on a Wanderlodge problem, they search the WOG website.
