Hello All:
Here is the problem with my 86 f150 4x4 v8 351 5.8l:
I just replaced the starter and solenoid, and charged the battery. Three days later, the starter died. While starting the truck at the solenoid with a screwdriver, (which worked), I noticed that the heat from the solenoid posts was literally melting the screwdriver, then the crowbar, ect. The previous owner had installed a switch to jump across the starter, so I hooked that up to see what would happen, which led to that wire catching on fire.
I am assuming that this might be why the starter fried so quickly, and am thinking that it is a high-voltage problem.
My question is, do I replace the voltage regulator, alternator, or both at the same time, and what amp should I get?
i dont know what to tell you except that if you can drive it to autozone or advance auto they can test your battery and altenator while its on the truck for free.
If you have a problem at the starter, or with the starter, it can draw excessive amounts of current(not voltage). I would find out whats wrong with the starter, and then you may have to replace the solenoid again. If you bought the starter from a discount store, you may have to get two or three before you get one that works.
The excessive current is what's burning up your homemade jumpers. Be careful and don't overheat the battery.
You said it worked for awhile, and then quit. So I am assuming you don't have a problem with the engine having too much drag.
