Re: 1995 stratos boat light problems
Follow your positive battery wire from the battery terminal to the helm. It should end into a fuse buss with individual fuses or a master 20-30 amp fuse for all lighting. If the fuses are good, get a test light to check to see if there is power going in as well as coming out of your switch. Use the test light to either work forward or backward to see where power is lost.
Your fuses may be good and corrosion has killed your switch. If none of the lights work 'all of a sudden', then more than likely it's a common power or ground situation.
