Trams Comm Failure

[Denis Bourgeois]

2007 Patriot Thunder Winchester III  After being parked for a couple of weeks I turned on the ignition to adjust the hydraulic levelling and got the trans comm failure message.  I the cleaned the battery connections as well as bulkhead fittings through battery boxes and all ground connections from the batteries. The owners manual says to check the 10 amp fuse at engine battery which I cannot locate. I also can't find it in the wiring diagrams. I checked the connections at the vehicle interface relays and all looks well. Does anyone know where this fuse is located?

Denis,
Not sure of location but suspect it is located on the same board as the 200A fuses for your batteries. It is (should be) located in the rear electrical bay, normally on the pass side, just forward of the battery bay.

Dennis, welcome to the Beaver family.

I have the wiring diagram book at home and will try to find this for you shortly.

There are some variables such as if your coach has the all electric option.
As Steve said above, The simple answer is check the fuses in the Electric box at the passenger side of the engine compartment.  Just remove the cover door and put at tester on the fuses there and this might show the problem faster than trying to track it in the wiring diagrams.
Alternatively I do show a fuse in line after the chassis cut out switch.  Seems like you would have no power at all to the chassis if this were blown.
My next step would be Ken at BCS.  1-800-382-2597
