My headlights and interior lights have a pulse, my alternator is charging strong, my car is not missing, but idling at about 550 rpm (stock cam). They seem to pulse with the engine. Where should I start?
Keep in mind this is a hurricane Katrina victim that has been rebuilt, so water has been a factor. Any help would be greatly appreciated. I wish there were a market for gremlins, I have a ton of them.

the water damage is a thing of the past, Im only doing follow up on corrosion issues, to look at the car, youd never know its ever even seen rain. Its been a daily driver for the past few weeks, and Ive put about 2000 miles on it since Ive gotten it, Im just wondering what this could be.

I agree with killacam on the ground issue. Check all ground connections first. If the grounds are small gage wire you might consider a larger gage wire for the grounds as well. I have a strong system that puts out 145 db with no cap and have no issues with dimming lights. I have however upgraded my grounds. Good luck, I used to have a 69 firebird and I regret everyday that I sold it.

update on the light issue, the lights are pulsing harder, and it seems to be affecting everything electrical ie. A/C fan, idle, etc...I have the wiring diagrams, but Im an electrical mooooooron, where would I start? Is there a main ground somewhere, or am I chasing a meelion wires around this monster?
Im thinking since everything is affected, to start there. Dumb it out for me like the last time

Well yes, there is a main ground so to speak. It's the battery negative terminal. Don't overlook the simple things - check for corrosion on your battery terminals and clean them if necessary. Also check the other end of the battery negative cable to make sure it has a clean and tight connection.
Beyond that there isn't a single ground location - each circuit generally has its own. The headlights ground to bolts on each side of the radiator mount, the interior lights ground to a stud behind the kick panel under the dash.
You might want to get your charging system tested. You might have a voltage regulator problem.

oh no, this is the Firehawk with these issues, my 69 has been good, the only problem Ive had with that one is a flat cam, hence the 467. I had another 69 a while back, I bought it when I was 17 and spent 8 years on it then sold it for a 99 T/A. I missed it so bad I had to buy this one. The only way to get over missing one is to replace it.
