Sorry guys I'm new to this,I really do appreciate all the help,

If I turn on turn signal to show left turn it's correct on outside of vehicle but it shows on the dash as turning right.and vice versa.i cleaned hazard switch with contact cleaner,I replaced hazard switch,bought 2 from junkyard still doing same thing.im gonna check out voltage regulator.i have a new alternator just put on,also put new plug on alternator.

Turn signals blink backwards on dash,fuel guage goes to full,everything works as it should on outside of vehicle....help?

85 720 turn signals blink backwards on dash,fuel guage stays full,temp guage registers hot,I cleaned hazard switch with contact cleaner everything worked well for ,2 days,everything working properly on outside
