Fuse Block Question

[jerrysdustydog]

Just picked up a '84 C-10 that had been parked in Texas for 7-9 years and am going through it. Looks like part of the fuse block has power and part does not. Are there more than one feed to the block? I've found I think all of the fuseable links and checked them out but am scratching my head on this one. I pulled the connector block outside the firewall to check for bad connections, and everything looks good, but maybe the A/C, power window circuit and possibly others don't have power at the fuse block. I hate to think of pulling the inside block apart, but if need be, guess I will. I pulled the breaker out of the fuse block that powers the windows but no power to either side of the position. Any help appreciated.

did you turn the key on?

The vehicle has three fusible links - two at the starter and one at the firewall junction block. 

There are two 12-gauge red wires feeding power into the cab through the bulkhead connector from the engine compartment.  One of the red wires receives B+ through a fusible link directly off of the starter 3/8" battery cable stud.  The other red wire receives B+ through two fusible links that are connected in series: one link connects directly to the starter 3/8" battery cable stud and feeds power to the firewall junction block above the back of the engine.  The second link connects to the firewall junction block then splits through a splice, running to the alternator output post and feeding the firewall bulkhead connector.  Determine whether B+ exists at the two bulkhead connector cavities before moving inside under the dash.

Thanks, will check again today when I'm in the shop. Looks like there is maybe something that should be plugged in at the top of the fuse block? maybe 6 or so ports like something is missing?

so you did try the key in all positions?

No Tim, the truck appears to have the wrong key and wont come back to  ACC. Have purchased another switch and have not gotton around to changing it out. I guess it could be the problem, only goes to start and run. I have what appears is something missing at the top of the Fuse block that has 6-8 blades? One position is Hot.

Post a pic of the fuse box... and check for B+ on the two 12-ga red wires entering the bulkhead connector from the engine compartment.

well acc wont really matter but some of the fuse panel only has power with the key on

Problem solved. Loose connection behind the fuse block. Thanks guys!!!
