Pre 1970 vs. Post 1970 Alternators / Systems -- SOLVED IT - See Post # 12

- Surprised you are back on the Alt/Reg again. (1) - Thought you had both tested and confirmed.
I have not read all your posts, but to re-cap.
(2) - Flickering lights at idle and jumpy amp gauge
(3) - Tightened amp meter feeder wires and fixed. (4) - Now you have the issue at cruise speed? (5) - Do you have electrical loads higher than anticipated from a factory car? (6) - Have you done the MAD modification?
(7) - Does the issue only happen when the lights are on?
(8) - Are the grounds from engine to firewall connected ?
(9) - From neg. batty terminal to rad support ?
(10) - Have the main feed wires in and out of the bulkhead connector been checked and cleaned? (11) - As well has the ignition feed to ballast/regulator through the bulkhead been checked and cleaned? --
--------- (1) - So did I (2) - Yes - (3) - eliminated amp gauge & installed a volt meter. (4) - Yes (5) - None - no radio (6) - No (7) - Happens with or w/o lights on. (8) - Cleaned, paint scraped & connected. (9) - New one 6 gauge (10) - Yes (11) - Yes. --------- Going with 70+ 2 field alternator and new style VR - see post #7 & 8. -- Hopefully that does it. -- If not - I will probably go with new under hood harness + dash harness, if needed, --- Already, had several look at it, run various tests etc., tried another dash panel, installed a new ign. switch, eliminated the dimmer switch, & light switch. -- Thanks for the help from ALL. -- Let's kill this series of posts, and get on to better topics.
