converter testing

[ibycus]

hey all... I seem to be having an issue with my power panel/converter.. It appears as though all my A/C circuits are fine, however, my battery is dead and none of the D/C things are working..

what's the best way to test to see if the converter has died?

thanks

With electricity, you follow the flow.
1. be sure you have current TO the converter (if no, breaker/connection)
2. be sure you have current AT the converter input (if no, wire/connection)
3. be sure you have current AT the converter output (if no, converter/fuse/connection)
4. be sure you have current at the battery. (if no, fuse/wire/connection)

When you find the first spot in that list without current, you have drastically narrowed down the list of possibilities, and should know where to look further.

We had a power surge a couple weeks ago and it literally fried 4 surge strips in our house... I'm hoping I'm wrong, but my fear is that it took out the converter too...

Here's a WF-8955PEC manual that may help you.

One thing you can double check is the AC Breakers. Physically turn each CB OFF then back to ON this will reset any that have been tripped.

Good Luck on your mission.

So look for 120 going into the converter for sure. You might have to pull it out to see in back where it is plugged in so you can test that receptacle for 120 (meter or try something else like a portable fan that is known to work). If no 120 there, check the circuit breaker--snap back and forth. You said the other 120 stuff works.

My converter (not a wfco) has a 120v fuse inside on the circuit board where the 120 cord comes in but you have to take the metal box cover off to get at that.

if I'm understanding you guys correctly, there should be fuses on the line side and the load side of the unit, correct? should they all be accessible from the front panel, or do I need pull the unit out in order to find some? All visible fuses appear to not be blown...

Make sure all fuses and all connections are clean and good, both in the converter and inline between converter and battery. Then test like westend said.

Measure voltage across the battery terminals. With the converter powered, you should see 13.2 VDC +.

Take the wires off the battery, make sure the 30a reverse polarity fuses on the converter or if located there, on the DC fuse panel, are good, and see if you have 12v.

If not, confirm there is 120 into the converter by its circuit breaker on the AC panel and also by trying something else plugged into the receptacle the converter is plugged into (if the converter is a plug in )
