For the past few months I have had an intermittent no start issue. Sometimes it cranks right up, sometimes I get one click then dead, no lights, no buzzer, nothing. My first thing was to swap the battery. Mine was old, past warranty and was an Advance Auto crap battery. So I got a Motorcraft. I immediately noticed no change. Still intermittent no crank issues. I called the Ford dealer and inquired about swapping the battery. they blew me off saying it must be a ground issue, cant be our battery.
So i purchased a repro negative battery cable specific for an 84 5.0. I took my time setting it up. Made sure all contacts were clean. Set up the ECM ground with the correct connector I got from out to pasture pony parts. Car was fine yesterday. today no start again. it finally started so i was able to get to my mechanic for my AC and when i was there it failed to start when he told me to bring it in. He put a battery pack on it that was fully charged and still no click, no start. He says he thinks the solenoid is going bad. I had a brand new Motorcraft solenoid in my garage so when I got home I swapped out the Bluestreak I had in there.
First;
I found this small burn mark on the Bluestareak. An indication it was failing?
Second;
I am usually careful when it comes to putting things back where they belong. When my motor was swapped 2 summers back I had my mechanic drop the engine and bolt it up, and I reassembled the components and put all the wiring back in place. but today I was caught snoozing. I put all the wiring back onto the new Motorcraft solenoid and immediately saw and smelled smoke. I pulled the negative cable quick. I sorted through the wiring and it turns out one fused link burned out. I had it on the positive terminal. Must have supposed to be on the negative side? You can see the broken link in one pic and the rubber block it lead to in the other.
Can someone tell me what that fused link is for and how to repair it? And which side of the solenoid does it go to? Right now the car starts and runs, so I'm lucky I didn't kill the solenoid or the ECM. But that fused link is dead and not connected to anything so I'd like to get it corrected.
