New Member, need some help. Good battery, no start, no power.

Also, trying to find a mechanic that actually works on a non OBD or carbed car out here is almost impossible. Nobody knows how to work on cars without a computer diagnostic. anymore. I am am 50 year old retired vet, no stranger to working on old cars but not much experience with electronics. I like the car as is, fun to drive and reminds me of being young again. Has a manual choke carb hoping to get EFI in the future once I get this no start issue fixed. Might leave the Demon grill on, not sure the original Shark Tooth grill will fit with the fender extentions and the Dodge hood. Headlight mounts look different and bezels.
Im trying to get out of obd/efi vehicles, i actually discount my shop rate for classics and street rods. Would rather do old school than work on the new junk.

a test light and a load tester are what i would use to solve this problem.
