Dead Converter?

2009 20' Flying Cloud with an electricity idiot at the helm. Here's the problem. Simply put: No battery charge at all from shore power or when plugged into the generator with the 30 amp cord. Five days in one spot dry camping with my Honda 2000ui is how I found out. 7-pin trailer-to-truck plug charged the batteries enough so I didn't have to shorten the trip. New batteries by the way. Plugged into shore power on return..no charge, no converter fan noise. Parralax (sp) converter. Can anyone target most likely places to check for gremlins considering, of course, my total lack of electrical knowledge? Somebody mentioned ground wires shaking loose? Thanks. Jeff

First things first....is everything else on the circuit working? Have you checked your circuit breakers? And is battery switch set to the 'on' position, not in standby or off? If you do need to replace the converter, go to www.bestconverter.com with the model you currently have, and they will suggest the best replacement, of which there are several good ones.

If you have 12 volt power from truck check 110 circuit breakers may be the prob.

Checked all of the circuit breakers..looked good. battery switch in correct position, everything else is working fine. Just no charge to the batteries.

Maybe a dumb question. What is telling you that the batteries are not charging?

cannot always tell if breakers are tripped by looking, manually reset them if did not cure probs. then continue checking every thing

Thanks for the thread. Double checked everything today including resetting the breakers, and checked all the voltages with a multimeter. Tightened up a loose converter ground wire as well (screw almost all the way out). VDC 12.10 at the batteries, plugged in. About the same unplugged. 120AC good coming into converter. VDC leaving converter read 20.0 (manual says it should be lower) batteries isolated. Battery charge was creeping up when I left (someone mentioned it should read 13.5 VDC with the trailer plugged in). Left plugged in for the overnight and will check all the voltages again in the a.m. The new batteries, installed by the dealer last month, are Interstate SRM 24 and from the looks of the online reports, that battery is not the strongest deep cycle on the planet, especially for boondocking (what I do a lot of). Optima Blue Tops perhaps? About ready to pull the fuse on the stereo (that starts up every time by itself when I switched from "store" to "use".

It sounds like the 20v leaving the converter isn't getting to the batteries. Maybe a bad cable? or connections between the converter and the battery? I wouldn't think the batteries would be bad already.

Dumber question: batteries full of water/electrolyte?

20V leaving the converter seems like a problem. I would consider a converter-charter that outputs 20v to be a paperweight, or an anchor.

I realize that old clunkers like the ancient Univolts produce unpredictable results without a battery in the system, but I think modern ones, even the single-stage battery killers, shouldn't do that.

My suggestion......

Give Randy a call at Best Converter. He will give the straight scoop on converter and battery replacement.

I changed out the OEM Parallax converter after installing two grp27 Lifeline AGM batteries. Along with LED replacements in all high use interior lights, the best boondocking upgrade we've done, much longer battery use.

If anyone cares, this issue was resolved with a 4-stage, 45amp Progressive Dynamics charger ("Our patented Charge Wizard® 4-stage system constantly monitors RV batteries and automatically adjusts your converter output voltage". in place of the charger unit in the 7300 series Parallax that went belly up. A little pricey but worth it. Works like a charm. Added a pair of Optima (AGM) Blue Top Deep cycle batteries to the equation. Boondocking here I come. Add a recently serviced Honda EU2000i and it all works. Mechanic found a pair of large wood screws from nowhere (one welded to the element) that were left rattling around in the parallax charger area and shorted it out (toast).
