I would like to test this befor installing.My truck is now a 12 volt system . Should I use some kind of resistor?
Also Where did they locate the on / off switch? Did the heater knob have an "H " ? Do most people rig up a turn off valve to shut off the water flow in the summer?
Any help would be appreciated. Happy New Year !

Since I had converted all electrical to 12 volts, I just bought a 12 volt motor and switch from Jim Carter Classic Truck Parts. I mounted the lighted rotating switch in an open hole below and to the left of the glove box on the dash. The heater really moves some air after I switched the fan blade and hub to pull air through the heater core. | | | | | Joined: Mar 2007 Posts: 65 Wrench Fetcher | | Wrench Fetcher Joined: Mar 2007 Posts: 65 | Since I was not keeping it original, I put some valves in the heater hose line so I could turn off the water flow to the heater during warm weather. | | | | | Joined: Aug 2005 Posts: 6,377 Ex Hall Monitor | | Ex Hall Monitor Joined: Aug 2005 Posts: 6,377 | A lot of people put shut off valves on the heater hoses for summer time use. Many used the under dash rheostat motor control for the heater. My 55 panel had that type of switch.
