Ok Yesterday I Killed My Truck Shorted Something Out!!!!
Looking At The Back Of Fuse Box/ On The Right There Is A Medium Heavy Blue Wire - I Have No 12v To It, If I Jump A Wire From The Next Post To The Left The Reuck Will Run But Will Not Let You Turn Off The Truck. I Can Put A Switched Jumper Between The Two Temporally Until I Find Problem .

Any Ideas ? I Checked All The In Line Fuses On Drivers Side Fender All Seem To Be Ok,swapped Out Ignition Switch With One I Know Is Good , No Help There, Really Lost On This One.

How did you check the fusible links? I think the blue wire is from the ignition switch but without FSM not sure. Both sides are powered from the fusible links and one thru the shutdown relay. You need to make sure you have power at each link at the firewall end of the link by using a test light or DVOM. The links can look good but won't be.

Test light,on both sides of fusable link, still havent founf problem but did put a jumper from red wire to blue wire with switch in line- works fine (Except have to turn switch on before hittong starter and shut it off to kill engine) Engine sounds normal when shutting down no diffrent sounds.

Biggest thing of all OD NOW WORKS AT COMMAND WITH OFF AND ON SWItCH, WHAT A DIFFRENCE(I`M LOVING IT)
I stil have to figure out my propblem this is only atemporary fix on the electrical.

That blue wire comes straight out of the ignition switch. The only protection on it is a fusible link. The feed wire coming out of the fusible link that you need to double-check will be red. Go check that again.

 

ok ill do it first thing in morning ,its dark outside now.
(No i`m not afraid of the dark) HA! HA!
