I am in process of putting a newer motor with 12 Volt Positive ground Generator in my 1949 Nash Statesman which is/was 6 Volt Positive Ground electrical system.
The various lights will be changed to 12 Volt light bulbs in lieu of the 6 Volt light bulbs, simple, RIGHT?
There is two 6 Volt motors, one for defroster and other for heater. I assume I will either have to reduce voltage to 6 volts and switch the ground conductor to the power supply and connect the tail of the power lead to ground to keep the motors running in same direction. CORRECT??
Alternatively, I could swap out the 6 Volt motors for 12 Volt negative ground motors
Lastly, and most tricky is the gas gausge, oil pressure gauge, and engine temperature gauges (all designed for 6 Volt Positive ground. All three gauges receive power from one conductor and are wired in parallel with the power then going to three sending untis which then go to ground.
It will be very difficult to get 12 volt sending units for all guages so I would like to cut the voltage to these three guages from 12 volts after the conversion down to 6 volts. Can someone help me with the sizing of the resister to acoumplish this voltage reduction?
Unlike the motors, I don't beleive the polarity switch will affect the guages. AM I correct in that ASSUMPTION?
I hope I have explained enough in detail to faciltate a response. Thank you in advance
