Rare Fat Steam Chest Jensen Big Power Plant needing help.

It may take a while but I am up to the task.

Rare find!

  The heating element area looks pretty clean.  I have an early #25 and
it would not heat up at all.  Open-circuit on the meter.  After close
inspection the joints between the cartridge and plug wire looked hinky
so I cleaned the cartridge contacts and plug wire ends, put it back
together, and just like that it heated up as it should.  A really dirty
engine but it cleaned up and runs nicely.



  Good luck with your project.  It will be very rewarding.  And it has a
riveted boiler - very cool.  I'd probably try it on air right away, and
if it runs and the heater is good try a steamup, even before cleaning. 

Good Luck,
Wayne

Good catch Gil.

Good luck with the restoration. Hope you have the missing parts for he dynamo.

I think the horseshoe magnet generators are easily the best looking dynamo they made, In my humble opinion. I have previously wanted to try making a horseshoe magnet generator, but it's a fair bit of work haha! In this case, if parts are not on hand, I would think you could find a magnet that is pretty close to the right size and shape, available off the shelf. Whatever you decide to do, please let us know! I'm sure this isn't the only engine missing magnets on this forum haha!
