Electrical battery troubleshoot
Yahoo Message Number: 144980
Hi There!

My batteries are not charging when I have my generator running or when I'm plugged in via my 30 amp cord.  They do charge when the vehicle is running.

Does anyone have any ideas?  I appreciate the help.

Thank you,

Mitch 2001 RB

Check the converter's 120-VAC circuit breaker, in the power center While the power center is open also check the two 30-amp 12-VDC converter fuses.
You may also have a bad transfer switch.
A voltmeter is a handy device for troubleshooting these types of problems.

Thanks Larry.

I checked the power center in the coach and none of the breakers were tripped and none of the fuses were broken.

Do the other 120VAC outlets works when on generator or shore power? Are all the wire set screws in the power center tight? (check these with all the power disconnected to prevent shorts or shocks).
 If so, time to get the voltmeter out and see if the converter's breaker is hot to the converter.
If powered, then check the converter's output, before the fuses.
If no output, it's probably the converter itself. Is it the original converter?

Yes 120VAC outlets work with generator or shore power and all the screws are tight.

I guess it's time to get a voltmeter.

I believe it's original but don't know for sure. I bought it used.

Thank you,

Mitch

Mitch, To complement my better home voltmeter and for only a few bucks, you can get a $3 or so voltmeter from Harbor Freight Tools (if in your area) that will do the job.  I seemed to have collected quite a few vehicles and I keep one of these cheapo voltmeters in every one of them.  It may not be the best accuracy, but it will sure tell you quickly if you are charging, have a bad fuse, or if you are getting 110 volts.

Good luck,

Ramon
