There is a big connector on the firewall just above the engine on the drivers side. It will have a black plastic cover with a bolt running through it. Try tightening that and see what happens.

Ok that worked for a little while then it did it again today. Tried tightening they screw again with no luck

You might have to separate the plug and add some di-electric grease and socket it 3 times and then snug the screw back up. That should help gain your connection.

Just make sure the wires are seated in the plug properly when you are done.

Ok sorry to take so long to get back with you. Plug with screw in it taken off sprayed diode cleaner in connection then added diode grease put back together and made sure it was snug. New altenator as of yesterday. And is still doing the same thing. Going to crawl under it in a little bit take the plugs of the emc and do the same thing to them and see what happens
