1972 chevy 350 .well this truck is a mess wiring does not match the wiring diagram no power to anything has HEI distributor. messed with it today .I find no fuse link like it shows on diagram it had a HEI DIST,in it before. he put in new one I took some pictures to see what you guys thought but don't know if i can post them on this site .anyway took fuse panel loose checked wires with tester no power accept on two small black ones on firewall put that back on got ready to quit for the day pulled light switch again all lights came on very dim battery is fully charged turned on switch, I guess I shook it a little radio starts playing turn to start nothing and everything goes dead turn switch back on and turn over with remote starter switch, will not hit . he has the one wire run from dist. to fuse block as it should be. something somewhere is killing power .could the switch be bad ??? I don't know you guys are the ones with the good answers. any ideas would be helpful thanks again guys for your time
