It's never been connected since I've owned the truck, and the tag on the heater box says "6V", so I've been reluctant to diagnose it. I was pleasantly surprised yesterday when I tore it down to see the motor (2.3 amp) was a fairly new 12V, and the heater core was nearly new.
Now to wire it. I have a period type heater switch that I would like to use. It has the light in the switch that comes on when power flows through it. The only markings on it I can locate are "ARK-L". It has two spades in the back; one for motor and the other for power, with a resister.
So, can I use this for my 12V heater? How can I tell if it is a 6V switch, or does it matter?
Thanks for your help.
