As many of you all have, I recently have started restoring the interior of my '75 02.

When ordering parts I decided to purchase a new hazard flasher from rogerstii, installed it and the performance of my turn signals improved greatly...and probably gave me an extra 20 BHP!

Anyway--i just got my car back from the body shop where they welded in a replacement floor pan, and they said my flashers were going off, even when the ignition was off. And yeah, the new switch just turns them on without a key in the ignition.

I put my old, weary hazard switch back on and flashers didnt come on by itself, but neither the turn signals nor the hazard switch work.  With the old one the hazard switch didnt activate, but it made the turn signals weak...kinda worked

My Question:

*Did the act of using a mig welder fry the relay, or the actual switch? 

*Is it a bad flasher relay or  a bad hazard switch?
