Pelican Parts Forums - 1969 Electrical Issues + Hazards, turn signals

I am hoping an electrical guru can chime in and keep me going in the right direction.. I am kind of at the end of my knowledge here.

I am having continued troubles working on my 69 electrical system.

Symptoms: Passenger turn signals and hazards are blowing fuses.

So far I have done all the basics like make sure contacts are clean and Ive added some new grounds to be sure. Harness is mostly undisturbed.

I tracked down /swapped a new hazard switch and that did not change anything.

I am measuring high resistance /ohms from battery ground to my fuse block. Fuses 1-7. I have a new fuse block on the way from retro.

If I isolate fuse #5 (flasher relay input) and put it on its own 12v battery, the hazards will function and not blow a fuse.

The input on the flasher (49) gets very hot very quickly which seems wrong.

Lastly, the flasher makes a different noise for each side of the car. Driver seems to make a normal tone for blinker and passengers seems unhappy.

This was word vomit post, but I am hoping something rings a bell to someone and can point me in the right direction, thanks!
