Thumbs down Converter, Magnetek 950-2

Out put 11.4 volts. Was 13.8. I think it had some thing to do with distroying one of my coach battries. The converter was new in 1992 and I checked the out put three days ago while installing a new battery. Have pulled it and bench checked today. I used a 50 watt light bulb for the load. My load output was 11.4v. No load was 12.8v. I'm not sure what to check. Polarity is correct. thermoswitches have continuity. Can you help this old man. Tanks in advance

Doesn't sound too good. The no load voltage should be around 13.6, not 12.8. And at 19 years of age, it doesn't owe you a dime. Time to go shopping.

I recommend Progressive Dynamics or Iota converters with the Smart Charge option. They are bolt-in replacements for the 950 and far superior.

Iota 45 amp converter

I installed a Iota 45 amp converter in our coach one year ago it has been working great it's plugged in 24/7. It is silent can't even hear the fan run and have not added water to the batteries.Glad I made the change.

While I agree with Gary that you really should upgrade that old style Ferro-Resonant Converter (no longer produced) to a newer 3 stage Converter, here are the documents for your converter PPS FERRO-RESONANT CONVERTERS DLR. Float voltage for yours is 13.8VDC. Most likely one of the diodes has gone bad. Yes, the lower 11.4 voltage will harm the battery.
