battery light on dash

[bbhereiam]

Good morning. I am new to the RV world and have a wierd issue and could use some direction. 2000 damon on a freightliner chassis, and it appears to be a delco charging system. Yesterday the battery light on dash came on blinking and bright. (I have a volt meter wired in on dash) I pulled over and while idleing for about 5 minutes, the light went off. Whole time battey voltage was between 13.2 to 13.8. A few more miles the light was back on but very dim. Any suggestions? Thanks

Had A similair problem. Voltmeter showed 13+ but MH wouldn't turnover. First checked cable connections they were fine. Good Sam service tried a jump no luck! Finally GS disconnected. ground cable and got MH to start. It turned out to be a bad cell on Battery, put new one in and no problems since.

I took the engine batteries in for testing, and one was junk and the other tested unstable. Going the DIY route (those suckers are heavy) the RV is up and running again for just under $200.00. S0 far all systems are go. Thanks

do yourself a favor and put a good meter on you battery terminals with the engine running. it should show 14 to 14.5 volts. then start turning on wipers, blower motors, etc. and see if it drops. the average auto truck system is set to charge at 14 or above volts.
