I'm still having electrical issues with my '66 Bonneville convertible. I posted here in the past and have completed the various suggested improvements but no final solution yet to my problem which is a pulsating electrical system that is worse under load.

Here's what I've done to date, installed a rebuilt alternator, new battery cables, new battery, new NOS voltage regulator, replaced ground straps with new ones from our sponsor, and cleaned the area under the ground straps.
After completing all of these things over time it seems to be slightly better in that now the ammeter stay pretty pegged until I hit the brakes and the tailights illuminate or I turn on the headlights. At that point the dash ammeter is pulsing and so are the lights.

Here's another interesting behavior. If I have the engine turned off and the ignition switch turned onto accessory and have the radio playing all is fine. If I engage the turn
signal level and the turnsignals begin flashing, the radio sound dips each time they light so the current draw to the blinkers is pulling power from the radio feed. I've also pulled the bulkhead connectors and shined up the connections but it seems none of this corrects the problem.

This problem (outside of driving me nuts) is not too bad unless I try and drive at night and the headlights are pulsing the whole time. Hitting the brakes makes it even worse so it's either a problem on the positive side or I still have grounding issues.

I'm counting on this group including our resident electrical guru George to help me finally figure it out.

Thanks in advance guys...........
