Alternator died, now no power at all

Thanks for the help everyone. Here's my problem.

I have a 69 SS350 thats was completely rewired with an American Autowire kit in 2015. The ignition is a Mallory 6A wired to an HEI distributor. The coil on the distributor has been bypassed for the Mallory.

A few weeks back, I was sitting in the car idling. The car shut off by itself. I jumped it and it ran for about a minute and then died for good. Typical alternator issue right. Well, yes. The alternator was dead. I replaced it. Problem is, I have no power at ignition. I have lights, dash, interior etc. But when i turn the key, I get nothing.

I replaced the ignition tumbler in the column a few weeks back so it's brand new. The ignition switch was replaced when the AAW kit was installed. All the fuses check out fine. The fuse block has power.

Could the alternator going out have fried the Mallory 6A? Could it have fried something else I'm not thinking of?

Thanks again everyone.

Re: Alternator died, now no power at all

Check the neutral safety switch. If that's good check for power at the starter solenoid when the
key is turned to the start position. If that's good the solenoid is probably toast. If no power at
the solenoid check incoming power to the ignition switch. Keep checking back up the line until
you find the fault. An electrical diagram will help.

Thanks @allanjs!
I did test the starter but bypassing the solenoid but I did not test the solenoid.

Re: Alternator died, now no power at all

I can't remember, does the 6A have an internal or inline fuse? Did you check that fuse? Also check your battery. Sometimes when your alternator goes it takes the battery with it or does some internal damage that doesn't show up for a few months.
