2005 Bounder Voltage Guage

[babock]

Onthe "new to us" 2005 Bounder (Workhorse)that we just purchased, Inotice that the battery voltage that is read at the LCD front dash meter is lower than what I measure right at the battery when there is a load on the battery. Obviously, there is a voltgae drop somewhere. Have others seen the same problem?

I've not tested at the battery(s) as you have, but notice small variations testing at the 12V outlets in the RV with a small inverter that also lists voltage...not much to worry about.

I am getting more than 1V differenve in my measurements. I am going to open up the battery control center which is on the right side ofthe hood and measure for voltage drops in there.

I did some more measurements last night. With around 8 of the light fixtures on inside the coach, I measure around 0.3V drop across the battery disconnect switch for the coach batteries. I measured from the input to the box from the coach batteries to one of the fuses on the circuit board. The voltage going into the box was eaxctly the same voltage as measured back at the batteries. The voltage varies depending on load indicating a resistive contact in the switch or from the switch to the circuit board.
