Monitor Panel on Winnebago
I am looking for ideas on the monitor panel of a Winnebago Journey DL 34 2001 model. There is a spring loaded rocker switch that allows you to check the charge on the house and chassis batteries. One switch, you just toggle it up or down for the appropriate battery. This might be very common on all motor homes or all Winnebago MH. Anyway, the house side shows a voltage which would appear to be correct since it is plugged into a 30 amp circuit… and charging. The voltage is 13.3. The chassis (or as I call them, the starting batteries) show nothing, just a blank. If I jumper from the house connection over to the chassis then the display shows the 13.3 volts as you would expect… this just shows me that the switch and display is working. Then I put a volt meter on the connection that (from the wiring diagram) is the chassis wire and I get only 10.19 volts. When I go outside and put the voltmeter across the chassis batteries I get 12.19 volts. I know the chassis batteries start the diesel up with no problem so I believe the 12+ volts are correct. It would appear that I am getting a voltage drop somewhere in the wiring. Now rather that spend a life time trying to find this, I was going to run a new wire from the chassis side somewhere and use it to monitor the chassis batteries. The wiring diagrams have not helped me find a logic (and hopefully close to the monitor panel) place to tie the wire in. Does anyone have experience with this? Most everything is in cable protectors. I am guessing I could pull it off a slide out motor (one is very close to where I need it). But maybe there is a better place. Again, any help would be great.
