I would check and see if you blew the 80 - 100 main fuse. This can happen when you reverse the batt. connections.

Yup, start checking every fuse. There might be a couple right at the positive cable end.

i did that right away, checked fuses and didnt see anything wrong with them so thought maybe had one that splits off pos cable but nope so was thinking there was a relay someplace. i just will have to pull out the tester this wknd and check voltage all over. thanks

Didn't they used to use a fusible link on those back then? There is likely a wire somewhere between the battery and fuse box that melted. At least that is where I'd start looking. They used to put them down by the starter on some cars but I seem to remember them up top on those.

Good call! I show four fusible links coming off the battery.

Fusible links will look like a regular wire but will be a different color than the wiring it is attached to. For example there should be white wires and white with red wires coming from the battery. The fusible links will be brown, red, maybe blue, or some other color other than white or white with red. I should say this is typically the case. It's been a while since I have been under the hood of a classic Toyota!

You could be having way more fun if this was a late model Toyota. The main fuses are bolted to the fuse lock and require almost the complete disassemble of the fuse block in order to replace. Then you can start looking through the several fuse boxes to find all the other blown fuses. After replacing all of those and finally getting it to start you can look forward to seeing just about every warning light on the dash displayed as the final slap in the face. Clearing codes from all 73 1/2 on board modules and computers and your ready to hit the road once again!

just an update. it ended up being the 80 amp in the fuse block. it looked good on top till i took it out. and yes jeremy it was great fun, had to take it all apart and remove it from the backside. needless to say i think my neighbor was wondering who i was talking to, if he only knew the words coming out of my mouth lol

Glad to hear you got it figured out!
