Parallax 7300

Hello to all the community,
I have had a 2003 RT popular for about five years and I just realised the old converter never worked.

I know it's not the greatest unit, but me being stubborn I decided to repair it as an electronics project.
I have committed over $100 in parts with no success so far.

I am no expert but I believe the unit should be working by now.

Since the schematic is unavailable, if someone has worked or replaced one, I would appreciate if you could post some pictures of the board.

Reason is that I think the previous owner(unavailable) got in there and replaced some components with substitutes not compatible with the unit.

Many thanks!

If you can wait until tomorrow I can take a picture of the circuit board from the non functional unit pulled from my 04190, should be the same unit and has never been serviced.

Very kind of you!
If you can focus on the logic part of the board where all the IC's and small resistors are, that would be great.
Much appreciated.
Daniel

Always camped in mild weather and no need for 12vdc except for the small lamp over the burners and maybe the ceiling fan for one hour at a time.
Always moved every few days so aux battery always charged via alternator.
Also never used the water heater or the whole water system.
More like a tent on four wheels...

Isn't there anybody in the whole community that still has the original Magnetec lying around?

How many years had that equipment?? not many I think. Good luck!
