ZF Tranny Help

[Gregory OConnor]

David, May be a good Idea to do what Jeff M. said and just charge up
the batteries. Then make your calls in the AM. When voltage is the
problem 11.9 is very different than 12.0 and maybe now that you have
charged up there is no longer a problem. I remember some one having a
problem when they turned on head lights. If it was me and I did
anything, I would isolate the power input and hook it up to one new
battery that was grounded to the coach. I think that may rule out a
short in one of the batteries on the bank that is now powering the ZF
I understand the circuit board is 6 grand to replace. ( maybe some one
can comment if a bad battery would reduce voltage and cause this
periodic failure)

I dont know much about electronics , but I know poking an awl wont
work on diagnostics in this case.

I hope it is simple and you make your trip
