Question about 2002 Ford F250 Super Duty SuperCab

1 Answer

I have tried two alternators on my 2000 F-350 diesel and it still is not charging. I have checked all of the fuses and they are good. Is there a hidden fuse or a fusable link that I should look for?

Check the positive lead running from the battery straight to the alternator. Using a voltmeter, check for continuity through the whole lead. Chances are, the lead is corroded on the alternator side. Cut the insulation back and look at it. If its corroded, you probably need to replace it with some 4 guage

Ford F-250 2001 Diesel Super duty The alternator will not charge the battery. If we run a jumper wire from the battery to the orange wire on the alt., it will charge. Where is the fusible link between...


bstivers1, As you stand in front of your vehicle facing the engine, look to the left of the engine and see if there is a black cover that says main fuse. Remove that cover and there should be another little fuse cover inside. There should be a 20 amp fuse in there. Replace this fuse because if you follow the orange wire from the alternator will may find that it leads to this fuse. I know that Ford uses this set up for their F-150's but I am not sure if they use it for the F-250's or for a diesel. Check this out and if I'm wrong then, with my apologies, feel free to resubmit your question. Good luck with this.

Battery light came on on my way home from work have super duty 250 diesel 03


Most of the time,the battery light means that the alternator is not charging,or not charging enough.Have it checked,or check it yourself,using a volt meter,attach it to the battery,either one of them,the reading you are looking for is,13.65,to 14.25,volts.Do this with the engine running,and the head lights on,and the ac on,high blower .If it reads any less,the alternator is not charging correctly,or not at all.Check the plug in on the alternator,and the large wire on the back of the alternator,to make sure it is tight,they will vibrate loose on a diesel.If all this checks out o k,then replace the alternator.Charge the batteries up all the way with a slow 2 amp trickle charger,this may take a couple of days to charge,but the slow charge is worth it,it will prolong the battery life,and have less load on the alternator,I hope this was helpful,and thank you for using fix ya!

Intermittent battery dead.


This is not an easy repair. The system has a short or draw on the battery that could be located anywhere. I would take to a good local mechanic. The time involved could be very high in excess of 4 hours just to find the problem.
So taking to a shop you can trust can save you a lot of time. I know auto zone does some basic test to check the charging system. The alternator and starting system to see if there is correct out put on the alternator and if there is a draw on the starter for free. I guess that would be a good place to start.

Good luck

Will not start


make sure both batteries are charged, clean battery terminals, make sure the wire coming from the rear of your alternator is snug on the positive battery post. I take it that it's a diesel-(you said batteries} One last thing to try if it's turning over good but not firing; CHECK THAT 10 AMP FUSE THAT SAYS: ENGINE FUSE. hope this helps
