fuse block power problems

[mocheese]

I was wondering if anyone could offer a possible cause and solution to my power problem.
I have no power on the "switch" side of my fuse block. Everything with constant power is still working fine. Here is a little background info. I swapped in a chevy 350 in my 1028 a while back so now I'm running 12v. The new electric fuel pump, along with a few other accessories, is wired to one of the free "switched" points on the left side of the fuse block. I have been running with this set up for about a year now without any problems. Few weeks ago I was driving around and the truck cut off. Turned out the fuel pump was getting power. Later I found out I lost power to just that side of the fuse block. Everything else works just fine. Any ideas?

sounds like it may be in the ignition switch. The TM's will give you the wiring info to check the plug at the bottom of your steering column. Changing to 12V will have no effect on the ignition switch or the fuse block, all of that was already 12 volt. probably in the steering column.

Check the junction block right beside where the glow plug relay used to be.

The "switched" sockets are controlled by the 20 Amp Ignition Fuse. #15 in the diagram

Thanks. I'll take a look this weekend
