We have a 1985 Frod F150 that my husband has changed the altenator, starter solenoid/ relay and replaced the battery and now the truck will not crank. When truck is just sitting there you can it the brake, horn or lights and it will make a buzzing noise. We have checked fuses and many other things, but we have not been able to find out what it might be. Any ideas?????
Have you tested the fuselinks? They are located on the positive side of the starter solenoid where the battery cable attaches. Also make sure the starter solenoids attachment is solid, it won't work if there is not a good ground to it.
