Hello, bought my first FGF on Labor day its a 68 with a 350 and has been sitting for about 35yrs (luckily indoors). When I hooked up a battery my left turn signal is flashing on the front, rear and dash like if the switch was set to left turn...but it's not. No matter if it's in left turn, nothing or right turn signal on the column it just blinks left. Any tips on where to begin ? Appreciate the help in advance
