Suspected Converter Problem

I not only think that way -- been there done that and then gone one to rescue a dozen other rigs. The WFCO sizzled into the dumpster so fast it got skin rash.

"Our fire pumps are not putting out enough pressure. Sure as heck it's a bad pump but I suspect there are some leaks in the system as well. So maybe it's a good idea to find the leaks first then replace the pump. after the leaks are fixed"

Badly undercharged those Lifelines have months not years to get rectified. When the Lifelines arrive at a critical juncture they cannot be saves by reconditioning. You're on a tick-tick-tick schedule like it or not and the cost of losing is going to be a whopper. There are not a lot of alternatives for recharging an AGM correctly. I won't get into the Meanwell Megwatt scenario here.

When you are replacing the converter with something with a triple digit IQ processor THEN drag out new cable and connectors. When cycled deeply AGMs demand a charge rate of 20%+ of amp hour capacity, not 20% of spec minus all the hotel loads that will suck a 40 amp converter down to 30 amps /2 = 15 amps. Inadequate.

A sixty or eighty amp converter will DEMAND bigger cable - the chances are excellent you will find your bad connection automatically.

Of course all this is predated on whether you want to sane those two 600 dollar lifelines or not. The ball is on your court...

So your suggestion is to not only replace the converter, but replace the cables now? Why stop there? Maybe I should just get a new camper.

I can't get onboard with your troubleshooting method as it reminds me too much of a lot of modern day mechanics. That is, just start replacing parts until the intended outcome is achieved. Sure, you'll get it eventually, but likely spend more than you need to. Of course, that's not a problem when it's not your money.

Your fire pump example is also dubious. You start the example out by saying the fire pump isn't putting out enough pressure. Using the water analogy, pressure equals voltage so it's like saying the converter is not putting out enough voltage. That is not the case here, in fact it's already been demonstrated that the opposite is true. You choose not to believe it because you don't want to.

I asked you if you would spend the money on gambling on the converter. You said you would. I believe your overplaying your confidence, so how about this?

You buy me a new PD9260 and send it to me. I will do nothing other than swap out the converter. If it fixes it, I'll send you the money for it. If that doesn't fix it, I keep the converter for free.

Still so sure?
