alternator wont charge

Did this problem crop up before or after all this work?

Divide the problem into

1--Charge/ output wiring
2...Field wireing
3...the alternator itself
4...the regulator

in no particular order

Start by disconnecting the field wire which runs back to the alternator. This was originally GREEN. Ground that alternator field terminal with a clip lead, start and run, see if it charges

If not, measure field voltage at the remaining terminal, with key on/ engine off. Should be same as battery. Disconnect and reconnect your ground clip. In subdued lighting you should see a small spark.

With the engine running measure battery voltage and then alternator output stud voltage.

if they are the same, and below 13 with engine running "fast" then not charging. If voltage at alternator is quite high but battery low, then you have a wiring problem in the output circuit

If voltage is climbing up at battery, it is charging and problem is elsewhere
