hey all i have a 73 vailiant and i think i might have a ground issue but not shur when i turn on the turn signals my dash lights and tac blink not on and off brite to dimm i have replaces the cables also if i turn on head lights the car wil sputter and shut off any ideas the car came with a 318 and i got from a old guy that was the original owner

 

if i remember right. ALL the electrics that go to the rear of the car go through the turn signal switch. so check the operation of the turn switch. it is a week spot.
