A few days ago, I hauled about 3500 lbs of flooring/tile for my parents. When I got it unloaded, I went to leave and had trouble starting (the cargo lights were on, but only for about 20 min). Well, I got her started after a few minutes, and once I got on the road, I realized the light at the end of the gear selector that lights up the word "OFF" was flashing. I drove it again today and its still doing it. Truck is running, driving and shifting fine. When I press the O/D button, it shifts in and out of O/D as usual...Just wondering if its an electrical issue that just so happened to come up when it did, or if it had something to do with the load. Truck is a 1994 IDI Turbo F350, DRW 2WD, all stock. Thanks...
