What is a rheostat?
I have a 65 mustang and I decided I would redo the heating system. The car hasn’t had operating heat since I got it years ago. I took the heater box out and there is no heat resister in the front of it and there’s no hole where there ever was one and I don’t see any wires for it either. I also noticed that the heater control in the dash looks different than the ones I see pictured in the parts magazines. I then saw a heater jumped wire that looks more like what plugs into my heater control switch and I am wondering is this what I need or do all 65 Mustangs have the resistor? Do I need to cut a hold and put the resistor in? |
It's basically an adjustable resister...
It can can adjust generator characteristics, dim lights, and start or control the speed of an electric motor. A potentiometer is basically the same thing, but I generally characterize a rheostat as more heavy duty, but the term "rheostat" is becoming obsolete, and being replaced by potentiometer. You can replace a HVAC fan controller with one, which gives you complete adjustment. The resisters in HVAC car systems are staged levels using fixed resisters for set speeds. Using a rheostat will just allows you whatever speed you want. The dash light dimmer you turn on the headlamp switch is a rheostat (potentiometer). If you had a resister pack like in a HVAC fan controller for dash lights, then you'd only have three - four fixed settings for the dash lights... |
