strange electrical problem, flasher relay Options

[jflash914]

We have a strange electrical problem on my sons 75 six conversion. With the engine running you can hear the flasher relay clicking slowly (should not be activated at this time) and when you put on either turn signal the bulbs flash extremely fast. Also if you set the emergency brake the red light in the gauge rapidly flashes with the engine running. If you shut the engine off and leave the ingition on all turn signals and emergency brake light flash normally. We checked grounds by the fuse panel, engine bay , transmission strap, front trunk area etc. and all are good. We checked bulbs and tried a new flasher relay and still the problem exists. We tried disconnecting the emergency brake bulb and also the turn signal bulbs in the gauges but that didn't help. We disconnected the tach and the problem was still there. Has anyone ever experienced this problem? I was hopeing DD could shed some insight into this issue.
Thanks!!!

If the dash lights flash when the car is on and the parking brake is engaged, I think that is normal, or I hope so, because that is what mine does, may have to hit reset button on master cylinder.

I had all sorts of turn signal issues, replaced the relay and it fixed it, used a 4 prong relay from a 69-70 VW bus($10 at local shop, vs more than twice that for the "Porsche" one from pelican, no offense DD) Plugs into the fuse block. I also could hear the relay click, and was told that meant it was working, which it turned out not to be.

My contacts in the signals were all oxidized a bit too, used a pencil eraser to freshen them up a bit. One of my bulbs had a very attenuated filament, for whatever reason.
