Hi all,
I have a 72 which does not have the nice U shaped blower motor mount in the engine compartment that the later years have. I'm operating under the impression that this bracket is the early stock mount for the motor assembly: However, since the ground is supposed to be intermittent (actuates when the red cockpit lever is pulled up all the way) I have the problem where, because the above pictured mount grounds the entire assembly, I'm always grounded causing the blower to start up as soon as I turn on the ignition. I've tested my ground/red lever as the actuator when the motor assembly is not mounted (thus not automatically grounded) and it works like its supposed to - lever goes up and the motor turns on. Is there a way to separate the actual motor from the assembly so that it is not grounded when mounted? Maybe the rubber piece in the first pic goes somewhere that I'm obviously missing? Is there another way to mount the motor assembly that I just don't know of?

I'm staying out of the turf wars b/c I like folks on both boards... (IMG:style_emoticons/default/grouphug.gif) |

Oddly enough, I seem to have an early main harness and a late ignition harness. There's an empty space for the green wire in spot #11 of the main harness and no sign of any wires to connect to the heater motor coming out of the main harness. Could have been the PO that switched ignition harnesses,or me during one of the numerous engine switches. (IMG:style_emoticons/default/confused24.gif)
Since I know the green jumper is what gets intermittent power from the relay (depending on whether the heater lever is pulled up and "grounded"), I'll just tap into it (the green jumper) and run a new wire to the blower motor. The jumper may have been in the wrong hole in the pic b/c it keeps falling out due to the jostling of these tests. Good catch - but since I don't have an early main harness the jumper isn't needed anyway, unless I wanted to have the new blower motor wire run from the front of the relay board instead of the rear. The problem I originally started "trying" to fix wasn't the problem at all since, in the end, I won't even need a ground wire since the motor is grounded itself through the bracket which is mounted to the engine.
