My plan is to have a precharge ciruit that is initiated by a rocker switch like this
The way it would work is i flip the switch and it sends 12v to turn on a 120vdc relay which allows 120v to flow the the precharge resistor. SO far simple.
The next step would be to route a wire from the other side of the precharge resistor to the lead on the switch that illuminates it. Of course i would need some resistors on the way so 120volts doesnt illumante the switch. How would i figure out what kind of resistors. Ideally i want the illumination of the switch to be proportional to that of precharge so when the controller is 90% precharged the switch is 90% lit.
The final, optional step would be to use a relay to lock the ignition based on how "lit" the switch is. In other words i would send a wire from the illumination lead on the switch to a relay so that when a certain voltage is reached, proportionial to 100% precharge, the relay clicks allowing me to start the ignition and thus charge the contactor. WHat type of relay does this?
I'm not very elcectrically inclined, so please be simple with your response
This sounds like a good idea to me....but....what do you think??
If it's plausable ill draw out a schematic
