Anybody a wiring genius? Been playing with my 66 fuse panel to try and sort out why over half of my electrical isn'tworking. Shorter list is the heater and battery guage work and iI have tail lights but that's all. Replaced fuses, no dice. Looking at the fuse panel figure in the shop manual and it shows 2 circuit breakers that are non existent on my panel. Haven't noticed any stray wires anywhere so I'm confused as to what goes where. Almost to the point of ripping it all out and starting from scratch. Any help, suggestions, greatly appreciated.
 
Maybe these diagrams will help you.

I have one issue with my car, every time I change the small 6 Amp fuse for the dashboard lights, they stay on for a while, then the fuse blows.

It could be a short somewhere or a bad dimmer on the headlight switch, or someone may have contented some wires where they shouldn't go, causing a lot more draw on that little 6 Amp fuse than it should have. I know all the bulbs are good and work, but the fuse keeps blowing.

I recall turning the dimmer control and that caused the fuse to blow, could be some loose or burned wires on the coiled part. I have not fixed this problem yet as it is on the low priority list, but the gauges sure look great with the back lights on.

Start back at the starter solinoid. Check for corroded or broken eyelet on the main post. Other possible place might be the gang plug right at the body especially if you have any underhood corrosion. Make a list of what all you have lost and it may be easier to give you a better location. (This is what I do for a living and I've got a 65)
 
On the dash light fuse problem an often overlooked issue is how the radio back light wire is wired in especially if you have an aftermarket radio put in. If it takes a while to blow, see if it blows in the center or by one end. Oxidation (even a little) on the fuse terminals can create enough heat to melt the inside solder and kill the fuse where you cant see it
