Random Electrical Issue
Hello All,
I have a 2001 F250 V10 5-speed that I've had for about 3 years with 60,000 miles on it that I drive about once a week. About 4 months ago I stopped at a convenience store for 3 minutes and when I came out truck wouldn't start. Turned over strong had fuel rail pressure but wouldn't start. Had it towed home and was going to investigate the next day but the problem was gone.
2 months ago I stopped to get gas and went into the store and came back out and everything was dead-no audible with key and door open, not instrument cluster lights....as if it didn't even have a battery in it. I pulled the negative cable from the battery for a couple of minutes and put it back on and it started back working. It worked until 2 days ago and had the same problem with everything electrical being dead and removing and replacing the negative cable brought it back to life as before. Any help would be greatly appreciated.

have battery "LOAD" tested.. 100 amp load test.. nothing less.
check battery cables... positive and negative.. and at the frame for Rust at battery cable.
as moving battery cable returns power/ground connections.

I had it load tested and the charging system tested and I checked all the battery cable terminations and everything tested good. It has been a month of once or twice a week driving and the problem has not occurred again yet....I will keep the post up as new events happen.

Likely because the bad connection at the battery was disturbed/remedied by pulling and inspecting/cleaning it. A connection can visually inspect ok, yet not be. You need to physically pull all of the battery primary and secondary cables/wires and clean re-tighten and apply spray sealer over each. Inspect the leads to the alternator in the same manor. Ill assume its a diesel with dual batteries(fuel rail comment above)? Follow all the battery cables through the starter solenoid down to the starter and clean. Next time it happens have the VOM (volt ohm meter) handy. Do a voltage DROP test. YouTube that.
