Interior Fuse Box Disassembly

Interesting disassembly video of the fuse box under the dash at 17:20:



I suspect the owner put in a larger fuse (maybe 15A) when the original one blew.

 

He mentioned after market accessory, so not necessary a cheap one....
Most likely used an add-a-fuse tap but it was more than 7.5A or not using a relay.....
So, must know what you are doing with wiring and how much current draw before add to the truck.

 

Listen again to the video, he starts with turn signal not working and adding resistors. Then switches over to the parking circuit not working. Simple deduction is owner placed resistors on parking circuit, not on the turn circuit(s) wire(s).

 

yes, good catch.
Car-care nut just stated the cheap aftermarket accessory burn it up, in reality it is the wrong wiring of the resistor most likely did it.
Does not matter how cheap or expensive the thing you added is, if you wiring it wrong it burn $hit up.
