[QUOTE="deadpool1, post: 440563, member: 21229"] lots of ways to skin a cat, said grandpa. F12, 25amp fuse keeps blowing. buy a whole new harness , oops none sold now, only used. and scalper prices. (nah) fuse F12 cab blows, and but not with , 2 wire connector is disconnected at the blower it self . so is not the blower shorted. steps to find it , ordered list, not wanting to blow a box full of fuses trying to find it, (a given?) well use thermal breaker in F12 slot, a CB? sold in all auto stores it is. ATC size or do my list below. [LIST=1] [*]Main battery NEG lug pulled and Isolated. (wrapped in say a clean rag) [*]F12 pulled [*]connect a DC power pack, power supply, or tiny battery charger to this F12 socket on the output side. (+12vdc power wire wire) [*]connect DC power pack (-) to ground to body ground. [*]turn on said DC power pack . (what does it do now?) [*]See it overload, even uses meter to read the voltage at F12 output. [*]pull connectors to from the right side , to the left 1 by 1 until the short is gone, (you see 12vdc so is not shorted now) [*]now you know what section of harness (UK LOOM) that is shorted. C1 or C1 or C7 wire. or the switch , or the resistor block is shorted. [*]done. ( examine the found bad harness section carefully, you will find it shorted) [/LIST] Before starting, we test the power pack first (zillions of kinds made and sold) tests first this: short the power pack clips first to see what it does shorted. ( sorry they are not all the same) some blow up now and are now dead, for ever (china $5 power packs?) even Lets the smoke out. bad. or just goes to[B][COLOR=rgb(226, 80, 65)] overload[/COLOR][/B] and its gauge pegs or lamp [COLOR=rgb(184, 49, 47)]LED glows "overloaded[/COLOR]" and or shorted. GOOD ! or like mine, I dial up 1amp 12vdc and if shorted it pushes 1full amp when shorted all day or week long. endless. and 100% NO HARM done ! this or any 12vdc pack that does not [B][I]blow it self[/I][/B] up, shorted, and a DMM set to Volts connected across the two 12vdc pack wire connections. [ATTACH type="full"]122261[/ATTACH] ignore the yellow jack, use + and - only , plus to fuse F12 and - minus to car body. [/QUOTE]
