Howdy all. I recently replaced my old broken converter with a progressive dynamics 4645. I followed the directions to a T. All worked well for a couple of days. That was 3 1/2 weeks ago. I just got home from work and went to fire everything up. The converter breaker was tripped and continues to trip when reset. No 12v anything working. 120v all fine. any ideas where to start.Did I mention that company is coming tonight?Ha.Thank you,Jesse

You have got a short circuit somewhere in the converter circuit. You probably need to pull the converter out and check all of the wiring. In the meantime, get a 50 amp battery charger, put it on the batteries, and plug it into the (working) 120v system. That will get you through the night.

Hi,Try disconnecting the negative battery cable. Does the breaker still trip?

neg disconnect = no changebatteries out = no changebatteries are 6.2v and 4.8v per the multimenterat this point im guessing either bad batteries (kirkland brand 2+ years old with my stellar maint.) or somthing left on. Or miswiring somewhere. I lean toward the first 2 since it worked for a couple of days.

Hi,You lost a cell in one battery. The converter may have burned itself out trying to charge that cell up.

Converter breaker trips..Help company coming tonight

Thanks for all of the help.
Slide out wire?

OK thanks . If those 12VDC batteries are reading that low on DC VOLTS they are done for sorry to say... No hope....

Something ate them up...

If those were 6VDC batteries and you wired them in parallel a couple of days ago might be the reason the PD4645 converter croaked on you...

12 v batteries. connected properly before they were removed.

Heres the update.

I got it working. Batteries are out. Im pretty sure they are done for but will get to them later...

I disconnected the "utility pigtail" as described in the instructions. I am unsure what it goes to but that is the next thing to check out.

What is your reading on the 12 volt system WITH THE BATTERY LEAD TO THE CONVERTER disconnected? The converter plugged in and working? That is your test. Don't overload the converter with too many lights on at once. Let the converter BE the battery. Take the batteries off line. Bolt all the positive wires together and tape. Same for the negative wires connected to the batteries. Ignore the series jumper cable between the two batteries.

How do i test the converter. I tried last night w multimeter between batt pos and batt neg on circuit board. Read 4.8v. That was with the breaker for the converter popped off.

All is not lost here.

Turn off the converter and install a known good battery. Your 12v stuff should run. Use a car battery charger until you have time to deal with the converter.

You can run fine with no battery. Lift a cable off the battery and continue with your date.
