Potential converter problem

Hey Bro.

I have a digital voltmeter mounted in trailer. But simple. Attach a voltmeter to your battery. With trailer connected to shore power. If it is need of charge it will indicate the "Bulk" mode, somewhere around 14V and you may hear the converter fan running. It may be close to charge then it should be around 13.6V and that is the normal mode (Absorbtion). A properly charged and maintained battery will after some time move to the "Float" mode, around 13.1 V, it's just maintaining charge and it will remain there with no significant battery uses. If you are staying on shore power a properly maintained battery will never be in the "Bulk" mode. So end of the day, plug into shore power and watch the batter go thru the 3 stage charging loop. You can periodically check battery voltage with voltmeter and get an idea where your at in cycles. Make sense.

I ran a 12V source from spare fuse in converter. Didn't tap into any existing line. Run wire from source and ground, add fuse, mount voltmeter - done.

Update:

Thought this would be a good thread to tag onto. I've learned a couple things about converters since mine died on our recent road trip. First is to carry a car battery charger with you. Once I figured out my converter died I was able to keep on rolling by just switching off the AC power to converter breaker and hooking up the charger to the battery. Second after removing the dead WFCO converter and examining it my conclusion is its JUNK! I found a number of the large ceramic power resistors had broken loose from the circuit board. I've sent that back to WFCO for warranty repair, for a spare back up, but have now installed a Progressive Dynamics PD4655 converter. It's pricey but I shouldn't have to worry about resistors falling off the circuit board and the converter failing.

It maybe simply that WFCO now has a new manufacture assembling their boards. The circuit board maybe a thinner, smaller circuit board traces and lands, or they went with a cheaper power resistors with smaller leads. I can't say what exactly is their problem but a problem they do now have. They also need to upgrade what they use to "cement" components such as these large power resistors to the circuit board. When I pulled the circuit board out it was so obvious that these resistors had broken leads due to vibration. As I said one of the best backups you can have for your camper and tow vehicle too is a cheap battery charger.
