Burnt small wire coming from starter relay

Just bought this ford truck, 1991 f150 inline 6 and last night i smelt electric burn. I looked under the hood and the relay that attaches to the right fender next to the battery. I saw where a wire had burnt and broke. i saw that it went to the alternator. not sure where else it goes and what they are for and why this happened. I need see that my battery light came on and the gage went to the low end of normal. What do i do?

    ok, but why did it burn up in the first place? and will it do it again if i connect back together and tape? The harness is the one that goes to the alternator and i noticed, i guess from it being hot, that at the connection at the alternator end was melting and some of the plastic dripped on the alternator case. So should i replace the harness? or the alternator and the harness?

    thank you i will do that. Just wanted to make sure that the harness or the alternator was bad. I did notice that it must have sparked on the hood because i saw a burnt spot there too. Right above where the wire had burnt hole and then melted the rest. So, you are right. It must have had a bare spot there and it grounded at the hood. Wow. So the harness is ok and the alternator?

    it may have had a bare sopt on it and it grounded out...thats what usually happens with them. after you put the wire back together check the rest of the line to see if there are any bare spots and if so tape them up tight

Nothing happens when turn key. 1984 ford f150 inline 6


Check the small wires to the starter relay for power when the key is turned to start. The small wires activate the relay. If the small wires have power, most likely the relay is bad.

You can bypass the relay with heavy jumpers. Make sure stickshift is in neutral or Park if its an automatic. If starter turns good with jumper, relay is bad.

Check under the dash to see if the bushing that connects the clutch pedal to the clutch master cylinder is wore out. They get wore and fall out.
