Hi all,
I've got another twin speed heater unit here but the resistor has snapped. I've also got the original from the car and my plan is to replace the dated curly wire resistor with either a wirewound or metal film one.
My days or electronics and maths are behind me so thought i'd ask here. A few facts to lay down first.
Motor - 12v 1amp (as per wiring diagrams and research)
Resistor on working unit - fluctuates between 3.6-4 when set to 200 on multimeter.
Don't know what wattage resistor i will need - or in fact what resistor i will need. I've trawled the internet most of the afternoon for someone that may have done this before, but no one has got a definitive answer! So, in the name of science, here we go!!
