TRIAD UTRAD TU-730-2 Power Converter Battery Charger Camper Marine Airstream - $89.99. TU-730-2, taken out of my RV 47. There is an upgrade available that changes it to an electronic converter/charger, with more 12 volt output avilable. While more charge amps, up to 45 amps, are available, the charging section is only faster to charge, still not a true three stage charger.

I have the 4 pagemanual for anyone that wants to see it.
By popular demand, I've scanned in the manual for the'Recirculating Toilet' that used to be in my coach. For thosethat are interested, each image should print out properly on an 81/2 x 11 sheetof paper. At least they print properly here.
Thisis the official 'Electra Magic Recirculating Toilet' Manual that Ireceived with my GMC. Seagate crystal report 7.01 free download.
Thesethree pages describe the proper operation of the 'Bathroom Facilities'as described in my official '1976 Operating Manual' for the GMCMotorhome.
This is the 12 pagemanual that came with my coach for the original stove. The Magic Chefstove unit was replaced by the previous owner with a gas cooktop andmicrowave. During the Spring of 2000 I replaced those units with a new gas cooktopand a Sharp microwave/convection oven.
I replaced theoriginal upgrade because the microwave got zapped by a power surge from my Onangenerator and stopped working. I figured that it was not worthrepairing. The older gas cooktop had leaky controls that caused a LP gasodor and I figured it made sense to get rid of both appliances at the same time.

I work at a Mobile Home Park here in Dallas. I have an elderly neighbor on a fixed income with an Allegro 30' Motorhome. This RV is permantly parked, and hooked up to electricity. The power converter is bad. Are there any fuses that might have gone out, or possibly a reset that I have not discovered? Can this be rebuilt? I am fairly mechanical, and willing to try any suggestions. The model number of the converter is TU-740-2. The motorhome is an '83, and I'm sure this is the original converter.
Any help would certainly be appreciated!
Thanks,
Milly

Milly,
Welcome to the forum.
That converter may say Triad Utrad for the manufacturer, but they sold to Magnetek and they sold to Parallax; about all that changed on the product was the label.
So, here is a link to the Parallax site for Converter info. The 740 is a 40 amp ferroresonant converter, and there is information on this page for it, and more detailed information on the 'Technical Documents Link' at the top of that page.
If the battery is bad or not connected, the converter will not work correctly - the output will be very low, around 10-11 volts. Have you checked that? The converter puts out 13.8 volts and tends to cause the battery to use a lot of water, so it may be bad if it hasn't been cared for. Is there another battery you can hook up and test it?
There should be a fuse or a circuit breaker in the battery positive line near the battery. With AC power off, will any of the 12 volt lights work? If the fuse is good and the battery is good, they should.
The converter should be powered by one of the AC circuit breakers. They may trip and not look like it; the solution is to cycle them. That converter should make a fairly loud hum when it is on - it's the nature of that design.
Try the battery and fuse tests, and maybe we can come up with some more thoughts on how to help her if it isn't one of them.

Thank you for the reply. Here is what I have checked this far.. I know there is power coming into the bus by checking the big black cord. The lights (12V) were working over the last few days, but the batteries are finally dead now. But any of the 110 outlets are not working. 12V stuff was working while 110 outlets were not working. The converter is not making any noise at all, no hum, feels cold and quiet to the touch etc. She has heavy extention cords run from the pole to help with heat and fridge etc. But there is no 110 power getting from the black power cord inside the bus, to the fuse panel inside the bus. There is power getting into the bus to the end of the black cord. Does this info help??

Oh, I also turned all three breakers off then back on and got nothing. Is that what you mean when you say cycle them.

Thank you for the info!!! Good to know that it might not be the converter!! I'm headed up there now to see if I can find what you are talking about. The fuse panel is in a closet and I believe the box you are talking about is right beside it. I will check to see if it has power getting to it and message back shortly.

The converter just converts the 120 volts AC to 12 volts DC. It sounds like the real problem is that the 120 volts AC is not getting to the AC circuit breakers.
Did you try turning on the air conditioner fan? If it runs, then much of what I'm about to type is immaterial. But that will be a test to see if AC is going through the circuit breaker panel. If it doesn't run, read on.
You say there is power to the big black cord. Does that motorhome have a generator?
If there is a generator, the big black cord and the generator output wires may go to an 'Automatic Transfer Switch'. This switch would transfer the power to the circuit breakers from the generator if it was running, or from the campground power receptacle.
That switch would be a metal box with three large cables: power cord, generator power and power to the circuit breakers. It is often located near the circuit breakers. If that switch has been overloaded and the contacts in the relay (think contactor like in a home type air conditioner) are bad, power won't make it to the circuit breaker panel.
To possibly save some time, look in the electrical cord storage area for a receptacle. Some of the generators were wired to an outlet installed where the main cord was stored and you had to plug the cord into it if you wanted to use the generator. Then no Automatic Transfer Switch was used.
If the A/C runs, but no power to the outlets, then another thing to look for is a GFCI outlet. That old of a unit may not have one, but check in the kitchen, bathroom and any outlets that are accessible from the outside. One or more may be GFCI and feed all the other outlets. If it is tripped, all downstream outlets won't work.
Check those out, and post.
If you want to take a few extra minutes to check the converter, you can run an extension cord into the MH as the converter should have a regular AC plug on it. Plug it in and see if it doesn't start humming.
