I went to install an electric brake controller and shorted out the pos red wire under the dash for the elec brakes. Now my truck wont start, I checked all fuses both in the cab and under the hood and found a large 30 amp gone under the hood and replaced it but it doesn't start. I also unscred the filter and turned the key, lots of fuel but I noticed no smoke from the tail pipe.

HHHMMMMM Wish I was there. I have never been good at electrical unless I can put my hands on it.

 

Check the relays, too.

 

this is why we disconnect our batteries when working on the electrics...

just a friendly point out...

 

yeah a relay could be bad

 

exact same thing happened to my friends 7.3 and but i couldnt remember if it was the relay or not. ill check with him and angelic0 is right about the batteries being disconnected while workin on stuff thats electrical. I blew my pcm on accident

 

sounds like a relay

 

check the fuse links at the solenoid and so forth

also check yhe fuses with a tst light

 

Check all your fuses. Underhood, under the dash, all of them...

 

it was the pcm
