AC/DC problems	Stacey Nass	1-2-08
I have a Jayco 12HW Select pop up. My problem started as my own mistake. Changed it over to dual batteries but made the mistake of hooking it up for 24v instead of 12v. even though it was only hooked up for about a minute until I turned on the outside porch light and it blew. I hooked it up correctly but now when I plug it into a shoreline I only get around 4.5 volts on the battery meter when the batteries are not hooked up and its plugged into the house. I have good power at the receptacles to run power but the Micro doesn’t have enough power to run and the propane detector beeps since the volts are low, the light will not work either. We only dry camp and I would like to run a generator to plug into to charge my batteries but can’t. I believe I messed something up in the power converter (ELX-30). The breakers and fuses are fine to include the small bottle fuse inside the converter. Should I just spend the $130 for a new converter or pay an RV place to check it out and hopefully find some small thing I overlooked.

Disconect the converter from the 12 volt and recheck its output voltage. Hooking it up 24 volt may not have hurt it but hooking it up backwards almost allways causes damage. If it gives 13.5 or better volts no load then check polarity and reconect and re-check. If it wont pass these tests its toast. Rember a small converter working against two stone cold dead batteries won't have squat for voltage anyway. Charge the batteries on a trickle charger until they read over 12.5 volts. Then the converter should be able to raise the voltage over 13.5. When this is all done and it has failed the tests replace the converter. By the way a dead RV battery will take a minumum 72 hrs to charge from dead. The gen set will help but it wont fully charge the batteries without you getting linched in the campground. Good Luck

My 1998 fleetwood fifth wheel has a three way switch to run the hot water heater off of 12V or 120 V- Can you tell me how to wire this switch?- I am also looking for a replacement ownwers manual on my fifth wheel also, can you tell me where i may obtain another copy?
