My 1990 Ford F-150
I have a 1990 ford f-150 5.0.
It stopped running at a stop sign and we had come to the conclusion that we though it
was the solenoid connected to the fender. So, i replaced the solenoid and when i put
the key in the ignition all of the dash lights came on and i was hopeful. But as soon as
i went to turn the truck on the negative terminal sparked and it shorted out. Now i have
no power to anything.
Is this a starter issue?
Im at a dead end and i have no clue what is exactly wrong with it.
A customer had his pickup towed in had a simular problem as yours, the trouble was black corrosion had got so bad that it actually cut the voltage supply completely out. Got my trusty terminal scraper and went to work on the battery cable connections, got them shiny clean and the same with the battery posts. During the battery post cleaning I found out why the terminals were so bad, the plastic seal around the negative post had been damaged and was allowing the gasses from the battery to corrode the connection, customer got a replacement battery so I put it in and used a terminal coating spray to help with future trouble and the engine cranked right over. Hope my little story gives you a place to check.
Yup - BlackPost. Parts stores have sold an awful lot of those relays (that almost never fail) because of a lack of battery maintenance.
