Ran the cruiser today after getting the carb rebuilt. It shut off on me completely died while driving around the hood. Now I am unable to start it or jump it. No electrical power at all totally dead. What should I check first? I swapped in a known good battery still the same. I'm thinking altenator but have no way to test it? Does autozone test alts if I take to them? I'll change the fuses as well. I did some searching on here, anyone think it could be the voltage regulator? Thanks.
