I recently had my HEI power wire hooked up to the IGN terminal on the fuse block. But now after I got the engine back in and wired up, there's no power to the IGN terminal when the key is on. Is their a fuse for that terminal anywhere or why wouldn't it work?
Thanks

Yes, it is fused but it does not have a separate fuse. That terminal uses one of the fuses in the fuse block. Believe it's the turn signal fuse (99% sure). Second from the bottom, right hand side. The connection between the two is on the rear of the fuse block.

It should be fused; at least the one on my 67 is. I don't have any schematics for a 72 wiring system but it but I'm sure someone here has one.

Thanks!
I have a shop manual with a schematic but I don't know what to look for. I'll check that turn signal first.

One thing I have run across is the junction block where the wiring harness and the power wire to the battery connect. It should be right behind the battery close to the back of the headlights.

Yup, had a loose wire there that had me looking all over the place.

72 doesn't have a block behind the battery. The car is a little different than the other years.

It was the signal fuse. It works now.
Thanks

Adam. You are a great help. The only advantage I have is that I've had my 72 for over 31 years. Couldn't find that block either the first time I looked for it. Also if you have a problem with that block you wouldn't have power on the BAT terminal either. The line on the block is the input line to the fuse block.
