hello newby here with a little problem I’m scratching my head over.
I am wiring up a custom set of LED lights. The intent here is to have a running voltage that is lower than when the Brake switch is closed and then would apply full 12 volt battery power.
Everything was working fine till I repeatedly cycled this switch and then the circled resister blew. (Literally caught fire).
It seems to me that when the switch is closed, I would have equal 12v on either side of this resister, so why would it have an issue?
I am thinking I will add a diode before the resistor so the 12v Brake voltage will not have a chance to flow back through it, but I guess I’m not sure why I have to.
Thanks for your thoughts.
