Here is my problem. I'm working on my '66 Corvette which uses two 12vdc electric motors to open and close the headlight buckets. These motors are 45 years old and parts are hard to come by. Someone has started reproducing these motors but they are $400.00 each. So I decided to reinvent the wheel, err, the system. My plan is to use a single motor mounted between the buckets with a driveshaft running to each one.
I would like to keep the orignal 'up/down' switch as it is very classy looking. The only problem is that is a single pole double throw switch which won't work with any motors I have come across. On the original motor (which is much like any power window motor of past or present), the case is grounded and their are two 'positive' terminals. Power to one terminal is CW, power to the other is CCW.
I have no idea how they wired these. I'm wondering if the wiring on a new motor can be changed to work like the old one. Or, if there is such a thing as a relay that would reverse the polarity of the wiring to the motor?
Plan B is to simply hide a DPDT switch under the dash near the old one.
Here is a diagram I made showing my current wiring. Please feel free to fill in the missing links on the bottom part.
