Thread: Heater fan problem - again

In order to make this easier I purchased a device called a PowerProbe. For DYI it is genius. Sure, pros use higher tech kit, but for me it just does it.

Heres one: Power Probe PPROKIT01 Red Professional Testing Electrical Kit : Amazon.com.au: Home Improvement

but there are others, some way cheaper. Combined with my kinda high end multimeter and a polarity sensing test light you are set for most issues like you faced.

Just refrain from using any of them on any SRS system.... Yeah, I know, but you may not always be playing with Classics.

Yes, I have one of the power probes too - one that handles low and mains voltage. I agree that one cannot have too many carefully selected tools.

In this particular case, the switch was fried so there was no simple way to chack the rest of the circuit. Ultimately though, it was my stupidity in not checking ALL the fuses that made the job so frustrating.
