HI, REALLY NEED SOME HELP ON THIS! 99 F250SD. My charging system is not working right. The battery light on the instrument panel is flashing even when the truck is not running and the ignition on. The haynes book says check all the fuses which are all fine. The battery is fine load tested and everything. I put an alternator in it and it still did the same thing.I checked to see if it had 12vdc on the voltage reg. and it does. I am really stumped on this one. Please let me know if you can help! THANX OD
Finally Found Out What Went Down. After Driving This Rig Over Two Months It Quit Running The Other Day. After Being Towed To A Local Garage The Mechanic Called And Said That There Was An Inline Fuse That Was Making A Connection Every Now And Then. After Replacing This $6.00 Part The Truck Runs Fine!
