Arnes Shift Pad - No Lights & Dead

2009 Monaco Neptune w/Allison 2500MH Transmission and Arnes Shift Pad.

1. TCM seems to be a Bendix model M3614081219 (maybe) two connections go to the shift pad.

2. Transfer switch was replaced because it failed in service, shore power was turned off, not sure if master switches were turned off. Ignition was off.

3. I changed the "cutoff switch solenoid" as it failed as well.

Currently stuck in Yuma, AZ on a lot and engine does start, but as mentioned no shift pad, so cannot move coach.

Think the bendix TCM may be toast, does anyone know how to check it? It says on the label ABS/ATC Control, assume this is the TCM for Allison, if not, I cannot find it.

Any ideas on what next to check. I am going to search the net to find out how much a new Control unit would cost, change that and see if I can avoid a tow (which means dragging it off this lot and trying to get it hooked up to a truck, I want a low boy type of tow if necessary).

Some thoughts

No idea on actual problem in your case.

I had a diesel no start issue 6 weeks ago but turned out to be fuel filter - user learning curve.

1. If unable to resolve yourself or via forums may research mobile diesel service for your area or alternatively if tow is necessary - ensure that they know what you have.

I have coach - net and used them and was satisfied with their service.

Good luck to you.

Shot in t he dark here. There is a fuse near the start batteries that could be the problem. Is connected to the plus side by itself, one smaller wire.
