Malfunction in the Chassis Accessory circuit(long)
I'm sorry that this is so long but I have tried to answer as many pertinent questions as possible.
Winnebago uses two solenoids instead of a B.I.R.D. to control the battery hook up. One is a called a Battery Mode Solenoid and the other is called a Battery Disconnect Relay. Both solenoids are new and operate properly.
The battery disconnect relay’s function is obvious.
The battery mode solenoid, connects the two battery banks together when the engine is running and is commonly called an Auxiliary Start Solenoid, if either battery is too low to perform it’s function, you push the Auxiliary switch to join the two together.
While in “Q” for the shows I noticed that my batteries were always the same voltage. They charged and discharged as though one. It was not a great problem at that point and we continued on with our trip, returning 2-2-20. Yesterday was my first chance to check out the problem and I found the battery mode solenoid control wire was hot. In addition to using the aux switch to operate the solenoid, the Hot While Running circuit will actuate the solenoid. Several functions are connected to that circuit and they all seem to be operating properly. At least the circuit is coming on when the ignition switch is in the run position and off when in any other position
There are two ways to activate the solenoid, you can use the aux switch or the ignition hot when running circuit. The aux switch is used is used as a SPDT momentary ON switch with the mover running from the switch to the solenoid coil, a lead from the coach battery to the open side on the switch and the hot when running circuit to the NC contact. I removed the switch and disconnected the plug and the power to the solenoid turned off. Checked continuity of the switch and it operated properly. When I hooked my meter to the hot when running wire and turned the ignition on and off, no power.
I believe that there is at least one relay actuated by the ignition switch that controls the Hot When Running power out puts. One for the DRL and maybe one for the control for the mode solenoid. I am an electrician by trade and a fairly good shade tree mechanic but I am not a vehicle electrician, I find it frustrating to work on a circuit without knowing how things are supposed to be hooked up. I cannot find a Ford schematic for the Hot When Running circuit.
I need help in finding the individual components of that circuit. Anybody have any hints.
