Spriggs4u Posted July 23, 2021 Share Posted July 23, 2021 can low voltage cause the dash and lights to act up? got a new dash for my 91 and only the service3 light and some other light come on, it doesnt run yet, waiting on a fuel pump. test button doesnt work either, can low voltage screw with things?
