it could be causing a short circuit which could be causing a fuse to get blown check your fuses

I can help ..but it's too late tonight. Obviously all the problems are centered at the charging system. You can help me by giving info on what was done so far and how skilled you are following instructions regarding a few simple tests ,I won't get over your head with tests but you need to know how to read a meter (Harbor Freight kind .. nothing fancy) BTW Nothing gets me POed like mechanics charging that much money then not standing behind their work

Sounds like it might be an electrical connection issue or a ground issue. I would first inspect VERY CLOSELY all electrical connects at the battery, alternator and fuse / relay boxes. I would also check the grounds. You are looking for loose, discolored or corroded connections.


Tom, I am the actual owner of the Super Duty. I went and bought a meter this morning but, to be honest I do not know how to use it (reading instructions now). I am mechanically onclined and follow dorections very well. Please assist! Thanks!

Tom Harmon

OK .. you got the meter so lets familiarize with it

Tom Harmon

We will be using DC Volts, Ohms Tell me the model of the meter so I can pull up a picture and direct you to the setting

Tom Harmon

I will start with checking a small brown wire that comes off the alternator ,,, believe it or not this is not only a wire ,, but a fuse that will fail if there is a fault. You can't see the fuse because it's insulated but you can check it with your meter


The multimeter is a Innova 3320

As I understand you have a 2003 Ford F-350 Super Duty Van is that correct? what size engine?

It's a 2003 super duty pickup 6.0L

Tom Harmon

OK ... It's not easy trying ti fix something this way .. but It's all we can do


I understand Tom. And I really appreciate all your help. Today I took apart the dash and checked all connections. Then I tested the batteries and alternator plug with key in on position. Started truck and the the batteries were slowly draining while running. So, replaced the alternator and so far it is running great. This is the 2nd time in 4 months that the alternator has been replaced. Any input you have would be great as now I am sure there is still an inderlying problem causing the alternator to go bad.

THANK YOU SOO MUCH EVERYONE I am so appreciative for everyone who took time to help me trouble shoot it was the ALTERNATOR AGAIN ....
