Not being overly good with wiring I thought I'd ask on here smile

This resistor that connects to the main power cut-off switch area smokes a bit when jump starting the car if the starter pack is connected for too long, it sits on the chassis and I assume it's some kind of current spike scape goat?

I'm wondering if anyone has had similar dealings with this part, it's not in a pretty state after its recent smoking episode so I am going to replace it. I would like to know if a can fit a better component or if this is a problem elsewhere in the wiring causing this.

Any responses appreciated, thanks in advance smile

The resister is there as a bypass to save blowing up the diode pack in the alternator when you use the cut off to shut down a running engine.

I suspect you are leaving your starter battery plugged in with the cut off switch OFF, thus the starter battery is grounding via the bypass resister and "cooking" it.

The short term fix is to remember to always leave the cut off switch ON whist the starter battery is plugged in.

The longer term solution is to wire the back up plug correctly directly across the battery so that it does not short through the resister.

Excellent thanks for that, sounds spot on! I don't quite understand this part, if you mean the Anderson plug then it is currently wired directly to the +ve and -ve terminal of the car battery.

Thanks,

If that is the case (not via the cut off switch) then there should be no path through the resister as is it no different to just temporarily having a larger battery fitted?

Certainly mine does not do that to the resister as I have on occasion left mine plugged in and the charger on to top up both the batteries at once.

It is not normal, so hope you get it sorted.

Agreed, I'll investigate further, thanks for your input.
