2000 7.3L alternator replacement = speedometer problem???
my wife was driving home the other day when the truck died on her. she had previously gotten a jump start to get going. ended up having it towed home on a flatbed towtruck. it's an f350, LWB, SRW, 7.3L, crew cab, XL model.
i took the alternator off, had it tested (it was bad), and put a NAPA rebuild on it.
she also said when it happened, all of the gauges pegged, including the spedometer needle (pegged all the way clockwise).
truck has since started up and run fine, except for the spedometer needle has remained pegged.
i checked all the fuses in both boxes...one each was blown: radio fuse, and the laptop port fuse.
any ideas on what else could be wrong? i've seen other posts describing the speed sensor, but this just seems odd.
thanks in advance for the help!!!
