The battery was too weak to start my son's '85 123 the other day. I put it on a charger and brought it back. I had no warning lights about a charging problem. I checked the charging system with a little tester I got from Harbor Freight. It says the system is not charging. I then replaced the voltage reg. in the alternator, hoping that was the problem. The little tester still says its not charging. When I put the new voltage reg. in, does it take a certain amount of time for the brushes to seat and begin charging? Or should it work properly right away?

I guess I'll take it to Advance and let them test it and see what their machine says.

I still have no warning light about the charging system. The light comes on when I turn the key so I know it works.

I have a multimeter, can I check the system myself?
