Heater motor replacement.
The original heater didn't work so I traced some wires, tightened some connections and then it would run. However it wouldn't run very fast. Soon enough it blew the fuse in the heater switch.
Removed the heater to investigate.
PICTURE Then removed motor and dissembled it just enough to see that the brushes were worn down to next to nothing, the commutator was very well worn, and lots of crud/dust/dirt inside. Seeing all that I quickly slid the motor back together and started looking for a replacement. If it was in better shape I would have oiled it and tried to keep it going.
Here's a thread in The Electrial Bay that goes into more detail on the motor.

Short answer is save your money, don't spend $45 + shipping online, instead go to NAPA (or likely other FLAPS) and order NAPA # 655-1022 for $33. (see alternate, cheaper!, part # for other heaters in the electrical thread linked above)
With motor in hand simple remove and replace, no modifications.
PICTURE 1 PICTURE 2 PICTURE 3 You may ask why I put a 12V motor in a 6V truck?
Because it'll still run (about half speed) and because in the future I'll do a 12V conversion. It works plenty good for now on 6V "full speed/hi"; the lower switch settings are too slow, don't use them.
Next post?? Changing fluids, considering rear axles, ordering seat belts... several things going on presently so more to come soon.
