A Couple of Newbie Questions

Greetings!
Im fairly new to Class A camping/traveling ( 2 years) and I have a couple of questions. Here is my unit:
  • 1995 Tiffin Allegro, Service Parts ID: 1gbkp37nxt3309330, 178.0, CP31832
    • V8 7.4L 454CID FI GAS N N VIN: t3309330
    • I dont know what this number is: 131 1ww9610249
Parts?
  • It has the original Magnatek Plus Power Center Series 6300 A 6325, 6332, 6336, 6345, 6350. Its very dusty and grimy inside and the cooling fan appears to have not run for many, many years.
  • I also have a pamphlet for the Inteli Power 9000 Power Converter from Progressive Dynamics: PD9020, PD9040, PD9055. I have no idea what this is.
  • I also have a pamphlet for Power Switch Model PS-250, 240 Volts AC 50 Amps/Pole. I also have no idea what this is.

My problem is thus; my two 6 month old house batteries will NOT charge from motor or generator. They will charge from 30 amp shore power. However, its hard to go dry camping with no way to recharge batteries.

Any kind of suggestions for this issue?

One more issue, the furnace is inoperative. Fan runs and provides seemingly good airflow, and ignitor ignites, but it never lights off. It appears to not be getting any propane. I have a full tank of propane and my propane water heater, stove, and cooktop work just fine. It appears my problem may be a bad circuit board or circuit board part, solenoid, or airflow flapper thingies? The circuit board and solenoid are way back against the outside wall of the unit and I would have to pull the entire unit out to access them. There is no access to the furnace from the outside of the unit other than the vents. I really, really do not want to mess with the propane linkages and then pull the whole unit out.

Any kind suggestions for issue number two?

I have had this unit for 2+ years and I really, really like it! However, it would be nice to be able to dry camp and have heat during the colder months.

My profession is a pharmacist with some repair skills but not very many (I know a lot about drugs but little about Class As). I would appreciate any type of help whatsoever.

Sincerely, Class A neophyte,

JW

You would appear to have two ( at least) problems .

The charging of the coach batteries , from the engine alternator and the gen set are two separate systems.
The PS 250 ( Is the name Todd on the paperwork ? ) is an auto transfer switch , that changes the power supply from shore power to generator when the gen set is started . If all the 120 volt outlets in the coach operate when the gen set runs , the transfer switch is probably ok.
The power converter , is the unit that takes 120 volt power and supplies the 12 volt interior power to the coach AND charges the batteries. This unit should perform the same on shore power and when the gen set is running.

Do the papers on these two units have photos of them?
If so can you find them in your coach ?

Do you have any brand and model info on the furnace ?
The " sail switch " AKA the "airflow flapper thingy" if not operational, the control board ; inside the furnace; would not start the ignition cycle .
Removing the furnace for testing is probably the only option .

Yes, they work. Including the microwave and roof air.


"Sail switch". I could NOT think of that term! Yeah, I'm assuming they're okay because the igniter is sparking after the blowers turn on. I'm just not too happy with having to take the whole thing out. =-(


Furnace is a Dynatrail model NT-30SP.



I'll supply pics in a moment.


Thank you SO MUCH for your help!

Your picture of the info sheet on the converter , the series and model numbers don't match the info on the unit it's self .

I'd say to take the numbers off the unit and check for a manual online.

Magneteh
Series 6300
Model 6345

Have you found the power switch in the RV yet?

Thank you skip426! I'm just wondering if I'm still missing something. There seems to be more manuals then there is hardware! Or maybe the previous owner removed or changed somethings when he traded it in? Well, I've got a bed, water, food, and a roof over me so I'm not doing bad at all. :-) Just a few things to fix.


And call me a real newcomer, but what do you mean by the power switch?

While looking for your manual I found the attached document. Looks to have some good information in it.

The magnetek seem to be what's pictured. I guess you could double check that the 12VDC to the battery when on shore power is actually coming from the Magnetek. Maybe there is a hidden Progressive charger?
If the magnetek is working anytime you get 120VAC to the black and white wires on the left you should get 13.5 or so from the wires on the right.

Here is the install from bestconverter.com that I used when I upgraded to the progressive.

Magnetek Upgrade


Work around; You could plug in a battery charger and just charge the house batteries with a portable marine/auto charger. (using the generator)
