HEI installed not charging, need help!

That diagram is AFU. You cannot tell WHAT that 4 terminal connector is supposed to be hooked to

Assuming the top of the ballast is correct, the brown is the resistor bypass circuit, which comes from the key, through the bulkhead, and to the resistor. The blue coming off the top of the resistor should go to coil +

The bottom of the resistor should be a common connection

Should be blue (power feed) coming from key, through bulkhead in "run"

Feeding OFF from there should be the regulator "I" terminal

Alternator field on 70/ later vehicles

As shown the carb idle solenoid on some vehicles

choke heater on some later vehicles

I cannot tell from that partial diagram what you have

That diagram cannot be for a 69, because none of 'em used carb solenoids.

It would help if you'd post info about whatever the heck this "GM HEI" is, IE is this one of the Chineseo import "ready to run" jobs, or something someone built, or just what?
