'67 289 with factory AC(from donor car).
Finishing up the last of the wiring on a full resto. Last electrical function to check was heater/AC blower function. AS explained below part of the blower ground wire is getting warm/hot and I really don't want to be that guy that burns a fresh resto to the ground.
-1st disclaimer - a PO had cut both the blower motor wires at some point and put a butt connector in before it continued to the normal female end. Butt connector is about 8-10" from where wire enters the blower motor and about 1-1.5" past the butt connector is the factory female connector.
- 1st check had not done final connection of ground wire so I plugged a factory style single male connector with a section of original wire intact(I cut them from an old harness to get a cleaner/better fit) into the ground wire female connector from the motor and just held the eye connector I put at the other end to a grounding point. The blower worked fine but the end of the wire got warm/hot enough for me to feel it on my finger and pull it off.
- 2nd try blower ran fine at all speeds and I checked the wire for heat. I noticed that the point at the female and male connectors got warmest/hottest and the section of wire passed the connectors to the end also got warm. The section of wire from the blower motor to just before the female connector seemed to stay cool.
Now the questions and the first one might the dumbest, especially from a guy on his 3rd complete ground up resto. I should understand this stuff better but maybe there is a short in my head after a long day on the car combined with the frustrations of having to modify a poorly made Scott Drake Inst. Bezel to get the lenses to fit.
- Meter on the end of the ground wire, turned on the blower switch and I get 12+V at the end of the ground wire, also used a test light which lights when the blower is switched on. Is that right?
- With blower switch off and checking ground wire for continuity on the 200 ohms setting(on my harbor freight freebie meter) I get 9.1.
- The wiring diagram(Osborn) shows the ground wire from the blower going to what looks like a male connector(not female as the PO spliced on), then into a separate wire that has "19C661 ASSY." across it before ending at an eye and a ground symbol . Is the "19C661 ASSY." just referring to that section of wire from the connector to the eye?
