Underwater lights (only one working)

[007]

Just noticed only one of my 2 underwater lights are coming on. Is there something simple I can look for re wiring or fuse? The dealer is great, but I hate to pull it out of the water just for this one item even though it should be a warranty item.

They likely share a common fuse/breaker. I start by locating the splice between the factory harness and the light's harness for the suspect light and probe the slice fr voltage. Use both leads so you are testing the B+ and B- at the same time. If you have voltage across the two leads, its the light. If no voltage, then move the meters GND lead to a known boat ground and test the harness B+. If still not voltage, move the meters POS lead to battery+ and probe the harness B-.
