No Voltage Help!!

I check a couple of my fuses after putting my rebuilt engine in and they don't have any power. I have a couple of pictures I would like answers to. The junction block on the firewall( should there be a 10ga wire ran from battery to the block). I don't have power on my tail light fuse and a couple of the other one that should power up at same time according to print.

Re: No Voltage Help!!

Have a look at your first diagram w/ the battery at the bottom. Measure the batter voltage. Note the red fusible link label. You should still have one. They often get replaced with plain wire, which is bad. I'll guess The point where the FL and two reds is the junction, which should have voltage to ground obviously. Then you can follow to the engine bay side of the fuse block and measure at the red wire.

There is a couple of fusible links hanging off of the starter solenoid underneath the exhaust manifold. Replace the starter lately?

Re: No Voltage Help!!

Kwmech its a brand new starter. Motor has no miles on it. Fraken take a look at this diagram and tell me what ya think. The battery has two wires coming off of it. One goes to the starter and the other goes to the tie points showing fusible link. Wonder if that's the junction block. This is a 1986 diagram but I would think they are similar except the computer part. At the moment I only have one wire coming off my battery and its going to the starter(the big 0ga wire).
