Thanks Steve. Physics is coming back to me. I printed your message out and will have to read it again. Very impressed with your in depth knowledge. Interesting point about the bulb. Apparently if the bulb fails, replace it ASAP as the charging system will no longer operate?
What happens when the brushes wear, do does the electric potential build up/magnetic field terminate?
UPDATE: REPLACED THE REGULATOR THIS AFTERNOON AND AFTER A JUMP START, THE HORN BLEW LOUD, THE LIGHTS WERE BRIGHT, ETC. I DROVE IT AROUND TOWN FOR 15 MINUTES TO BE SAFE. PRICE OF PART $34. THANK YOU ALL FOR YOUR HELP AND MONEY SAVINGS FOR ME! A TECH WOULD CHARGES ~ $250 + LABOR FOR A NEW ALTERNATOR = ~$350.
