Guys, I've had this mod in my car now for almost a year and it works wonderfully. However, about 2 months ago, the momentary side of the DPDT switch (brakes) started smoking whenever I engage it for more than 3 seconds.
I finally tore it apart Sunday and confirmed that the smoke was indeed coming from the momentary side of the switch. The DPDT switch is pretty much identical to the OP, with a 3A rating. The funny thing is the clutch side works fine and I can leave it on for minutes, but the brake one can't seem to handle the current for just a few seconds.
Does anyone know how much current the brake side is passing? What if I put a resistor on one of the wires, would that still work or does it need a complete short for it to trigger regen??
