Ford Alternator fires

Twice in the last 5 days I have seen alternators in Fords start on fire. I did a little checking and there is a caution I found out about for you guys running Ford motors. The 3 contacts on the pigtail when installed on the alternator must be squeaky clean, that means take a pen knife or something and clean out the inside of the connectors. Then, make sure you use dielectric grease on the contacts. What is happening when the alternators start on fire is that the contact is poor, heat builds up, the alternator burns. If your alternator is too hot to put your hand on after just a few minutes of running then you have a potential problem. Hope this saves someones motor, the first one I saw a couple days ago almost had a very nice built Mustang go up in flames.

Re: Ford Alternator fires

I've heard this before, when a buddy of our's tow rig's alternator died (no fire) on the way to a long-distance ride one time & we had to stop at the auto parts & get a new one.

Thanks for the tip for everyone
