International.  The heat here in Texas has made it just about 
impossible to get much done.  Hopefully that will change during 
October.  We have our problem with refrigerator/pumps narrowed down 
to the converter charger.  We blamed some of our problem on the heat 
thinking heat was activating a thermostat and shutting the power 
down.  Yesterday we pulled the univolt out, sat it on a ledge with a 
fan blowing directly on it to keep it cool and everything was on the 
fridge and the pump.  That did not help at all, it still shut down 
after about 15 minutes.  Gil doesn't think it is the capacitor but 
does think the thermostat is not functioning properly.  Does anyone 
ever work on these converters?  Gil is very knowledgeable about 
anything electrical but our Airstream just says to remove and send to 
the factory.  Or would the best path be to purchase a new one?  The 
models I have pulled up on the internet seem to have more AMP power 
than our Magneteck (120 Volt 6HZ 7.25 AMPS 12.0 Volts DC (then it 
says in prens 40 AMPS total).  By the way this is not the original 
Converter because it has been spliced in.  Would our wiring in the 
trailer handle a higher AMP rating?  I am no electronic guru so I 
hope these questions make sense.  Thanks in advance for any 
suggestions about the wiring.  Pbran@aol.com
