'Humming' from the converter November 09, 2014, 10:27:52 am Yahoo Message Number: 149392Pat and others. It could just be the fan turning on and off. There is a fan inside that runs when it gets warm. If it is real quiet you can hear it. It is Normal. Magnetostriction causes all transformers to hum a little, but is normal also. If the converter is working, relax. It is not a 'ticking time bomb'.

Re: 'Humming' from the converter Reply #1 – November 09, 2014, 12:36:02 pm Yahoo Message Number: 149394I agree that while the hum can be irritating, nothing dramatic is likely to happen.But the old converters still have have two issues. 1 - They are very slow at recharging batteries and nearly worthless on a generator when boondocking. 2 - They tend to overcharge batteries and "boil" off water when left on shore power for long periods.Our batteries lose very little water since I put in a PD 9270.Art
Re: 'Humming' from the converter Reply #2 – November 10, 2014, 05:51:33 pm Yahoo Message Number: 149420Well, my main concern is what will happen to the batteries if they get overcharged - and after a few days of shore power, I'm starting to have problems with them holding a charge. Going to check the water levels tomorrow. I'm unplugged now, but definitely want something to protect (and to avoid replacing) the batteries. So, would an RV supply/repair shop be the best place to go, or should I call my friendly local electrician?Pat PS So glad it wasn't a bomb I was hearing RonB

If you're a Good Sam member, and there is a Camping World nearby, the installion on a purchase from them is reasonable. My buzz box was easy to replace (not in an LD), label the plus & minus (+12 Volts and ground) wires to the fuse panel, unfasten them from the old box, unplug the old box from the AC outlet and remove a few screws. The new converter fit in the space where the old one was (doesn't always happen that way), so all I had to do was fasten the new one in place, connect the 12 V wires from the fuse panel and plug it in. If the laws of Murphy didn't strike, you're ready to go.RonC2a Re: 'Humming' from the converter Mon Nov 10, 2014 3:51 pm (PST) .

Re: 'Humming' from the converter Reply #4 – November 11, 2014, 02:44:27 pm Yahoo Message Number: 149449I thought I read some where that you can have a disconnect switch or something like that when your plugged in to shore power so you won't over charge your battery or was it when you are storing your rig ? ? ? ?

These switches prevent anything from charging--or using!--your batteries, so they are useful only when your rig is in storage.Andy BairdTravels with Andy
