Hi Everyone,
I have a 2011 Think City Electric car that has a bug. It is a known problem with these cars where if you turn the car on with the heater controls set to on, you can fry the pre-charge resistor in the battery pack. The result is a bricked car with the possibility of it never running again.
The solution to the problem is to always make sure the heater is off before starting the car. As long as the heater is off before you start the car you are fine. But all it takes is forgetting one time!
I would like to wire in a switch to the wire running to the heater controls to ensure there is no power to the heater when the car is started. I have been looking online for a momentary kind of switch that resets itself to off when the car is switched off and stays off until the switch is turned on.
I found an scr switch that looks like will work. (also called a thyristor switch). When turned on, it stays on until the power is cut. When the power is cut, the switch reverts back to off and stays off until it is turned on again.
I need someone knowledgeable to tell me if this will work, or give me other ideas of what I can do. The heater fan circuit has a 12v, 20 amp fuse so the switch would need to be able to handle that. If there are other ideas, it would need to be automatic to ensure the heater is always off when the car is turned on.
Thanks for any help you can provide!
Brad
