Electrical gremlins

[ottoman562]

OK Fellas., Here's one I haven't seen in any of the forums. I have a 66 Chevy Stepside with 250 C.I. inline 6, recently restored in my shed over the winter, still bone stock except the flat black paint job and a hidden stereo in the glove box If interested you can see pics here

I've been enjoying the truck going on three months or so since completing the restoration. Last Saturday I take it out after a quick wash and on my way back I notice when I apply the brakes the turn signal indicator in the dash stay on instead of flashing. So I make it back home, turn the ignition off with my foot still on the braike and notice that my GEN and Oil lights in the dash are flashing. So I turn the ignition back on and get out of the cab, look at the taillights and now they are flashing. If I apply the brake they stop flashing. All lights except the rear turn signals work (rears are constantly flashing if the ignition is on) I have a brand new turn signal switch on the column, brand new taillights, brand new headlight, brake, reverse switches and until Sunday everything was working as they should. I checked the ground under the bed and its seems OK.

So., are there any GREMLIN SLAYERS amongst this bunch??
Could really use some help...
