Ranger Mods

Hi

I got a problem with an new Raptor, it seems the DC converter which i believe sits above/behind the fuse box in the car

It emits a high pitched squeel, its been replaced, but its now doing it again

I believe this is the converter for the power point in the back, i dont have anything plugged into this however

Wondering if anyone with a px3 has had this happen

My PX3 XLT makes a very high pitch/frequency electrical noise for a brief period (1-2mins) after switching the ignition off.

Honestly, it's under warranty. Next service have them replace the inverter.

Mine does it too. I kind of assumed they all do.

Shouldn't do if it is working correctly.

Main problem with these is the overload protection does not work. They are only good for approx 200watt before they go bang and all the smoke leaks out.
