1966 mustang electrical problem

While charging the battery on my 66 Mustang with a 289, something happened, and I lost the entire electrical system. No starter, head light, gauges, nothing. The fuses all checks out. One thing that comes to me, is something to do with a fuse ling between the starter solonoid, or relay, next to the battery, that apparently can burn out and will cause precisely this type of problem. The advice that I seem to recall is to splice that link and then re solder it. The question is, where exactly is that link? Is it on the starter cable itself? and if so where? The only spot that I can see, is at the very end of the cable, almost at the point where it attaches to the relay, where it looks like a small firm rubber knot. Any advice would be appreciated.
Thanks
Jack

Check the positive cable connection clamp at the battery. I had a similiar problem with My F150 truck. The clamp was cracked (hard to see) and was loose enough to cause the electrical system to go dead. Changed out clamp problem solved.

Well Im not positive on that old of a car but I know for sure that newer cars are that way.If it was me before I would go splicing anything I would find some wire of the same gauge and make a jumper to see if it solves the problem then go from there.

Does 1966 mustang 289 have self adjusting valves?

If it's a "K" code hi-po 289, then it has solid lifters and the valve clearance is adjustable. If a standard 289, then it has hydraulic lifters which are zero clearance and self adjusting, i.e. there is no adjusting screw on the rocker arm.

My 66 mustang pops when I turn it right. I think

ball joints are your problem, but also have your tie rods checked. if you can move your tie rods with your hand they need to be replaced. check your balljoints by lifting your car and grabbing a front wheel and moving it up and down if you feel slack, replace balljoints as soon as possible, as it is dangerous to drive in that condition.

66 Mustang- 289 V8- has an intermittent surge and rattling noise

Sounds like crappy gas. The 289 may not like pump no-lead and the rattling sound you are hearing may be pinging / knocking.
