hey all,

have a '91 ford f150 pickup (what a great car :-).  my radio went out 2
months ago and now the odometer went out (it's a hitech digital one
from 91!).  anyways, that turned out to be a fuse (haven't tracked down
the radio issue yet).  i installed a new one only to have it blown a
day later (not sure what we did other then just started the car).

on occasion, the interior light comes on and won't shut off.. have to
jiggle it a little.
i recently replaced the terminal connectors for the battery.  after a
day of hauling brush, the car just wouldn't start!  swapped in new
terminals and no problem starting since.

obviously i have a short somewhere (i hope the radio isn't fried) but i
sorta need the odomoter/speedometer running.  how does one go about
tracing it?

i also have access to an odb reader.  will this help any?

thanks!
