I have a 92 RAM 250 Diesel.  This morning it died after running about
15 minutes.  It would not crank but everything else worked.  I towed it
back home and did a little poking around.  All the fuses are OK.  The
alarm system is OK.  (Although it does trip after a while, but I can
reset it.)

I then unplugged the starter solenoid plug and shorted it.  The starter
works.  Then I went looking for fusable links.  I found one open.  It
is orange and is 1 of 5 that comes out of a large wire that directly
hooks to the battery.  The link that is burned hooks to a wire that
also has a white fusable link hooked to the same place.

I stripped back the insulation on the burned link and twisted the ends
together.  As soon as I turned the ignition switch to the 'on' position
the link burned open very quickly.

I do not have the shop manual or a wiring diagram and Google didn't
help with the diagram for my truck. I'm way out in the sticks so it
will take several days to order one.  In the mean time, before I start
opening wire bundles and tracing the wire, hopefully, some one here can
help me. Since there is a fusable link, I'm assuming that this is most
likely a documented problem.

Thanks in advance,
Lee
