Battery Readings vs. Monitor Panel Readings

by Larry
(Jackson, MS)

Question:We have a 2009 Jayco Greyhawk 31ss Class C motor home. When I go out the night before camping to turn on the refer the Monitor Panel shows my battery at full charge. When I return the next morning the Panel reads "0" charge but the voltage meter test at the battery posts reads 12 volts. What is happening? Thanks!!!!

Robbie: You have left out a critical piece of information and that is do you have power in your RV when the panel reads 0 in the morning? If you do have power then your monitor might have a loose or bad connection but if you don't have power in your RV then you have lost power from the battery to your converter. You would need to use a test light and follow the power until it stops. If the problem is only the reading at the monitor you could also have a bad monitor. A reliable fix is to install a digital gauge that reads all the time that you can see in a easy location. Also be sure your connections at the battery are clean and tight. Remember to clean the terminals correctly you need to disconnect the wires and clean all areas of contact.

Thanks for the Question Good Luck,
