Is My Converter working ??

[neil.ervin]

Using the voltmeter I crossed the + and - converter wires going to the battery. The posts are beside the 12v fuses. I read 13.9v which means the converter is putting out normal 12v electric.

However when I cross the same wires in the battery box (still connected to the battery terminals) I read 12.22v. My solar controller reads 12.08 on the battery. During this time my solar is not in play, not putting out current as the trailer is backed into a garage, and the controller panel shows it is not charging.

I think my next step would be to disconnect the converter wires at the battery and cross them with the voltmeter.

Thoughts?

Neil,

a couple of issues come to mind...

1. did you remove the fuses in your panel that the battery wires are connected too? Sometimes the connection gets cruddy - while the fuses are removed, also check the the connections where both battery wires are attached to the fuse panel - sometimes the set screw for the wire cables becomes loose enough for contact to be lost.

2. when you checked the voltage at the batteries, were you contacting the cable ends or the actual post on the battery? If you had some corrosion present in the cable ends, the voltage reading might be different between the cable end and the battery post itself - remove cables, wire brush cables and posts and reattach - spray a bit of WD40 type stuff on the connections when done.

3. do you have a two-prong type plug in the battery cables, inside the battery box? Our older AS has these plugs - if you have the same, you might unplug, clean and spray some WD40 into them and reattach.

From your description, your converter is working, but the current isn't getting to the battery posts...you're going about it the right way, you'll just have to check all the connections between the two components...

Good hunting....Ray
