I've had my 58 Apache for 15 yrs with very few issues. It is stock and has a 235. Recently when taking her out for a drive I noticed the temp gauge started out with needle all. The way to the cold side of gauge , actually out of sight to cold side. When heated to operating temp, it registers well below the quarter way up the scale. Should I replace the sender or gauge or both? Anyway to test gauge ? Thanks for any advice.
