Dude I had the same problem and I ended up taking it to a pro to get it fixed, cost me about a 100 or maybe less if I remember right. Sorry for the lack of help.

Ok after banging head against wall for hrs I think I got it. Only thing I did was take brake light switch off and put it back on...don't know but it worked. Now back to the brakes lost a wheel cylinder also

with engine swap complete i went to take this thing around the block only to realize that turn signal and brake light fuses were blown once again. only thing i can think that is wrong is the headlight switch going bad or brake switch going bad or both. everything else has been double checked and rechecked behind that.
If you can't fix it with a hammer and a welder then your gonna need a new one!

I probably shouldn't say this but I installed a painless harness in a friend's 68 Firebird for him and had a lot of problems with weird stuff going on. Maybe they're not all like this but that was my experience. He asked me to do it because I used to work for an automotive electric place wiring cars. Once you go with a painless harness, the factory schematic goes out the window which makes troubleshooting way more difficult. What you describe sounds like a short not a bad ground. Did the harness come with a new turn signal switch? They can cause lots of trouble especially if you have a tilt steering column. Did the painless harness come with a schematic, I can't remember if they do.

yeah it came with all new switches.when i put in the painless harness i changed steering column also. ive even talked to the tech guys at painless. all seems to point at headlight switch for some odd reason.

Yea the headlight switches can be troublesome especially if it is an old one. Maybe yo can disconnect or bypass it to see if the problem goes away. I think they're pretty cheap anyway.

true. but i cant get the problem to "duplicate" itself to track it to a switch. it might blow fuse once with headlights on and the next time i cant get it to blow. thats what is making me believe its a combination of both headlight and brakelight switch. i havent found any amp draw indicating a short anywhere.
