Hello, my name is***** will assist you today.

Crest liner does not provide a detailed wiring diagram for your boat. They would almost consider that a trade secret. I am very good with 12V DC and can talk you thru how to troubleshoot the system. You will need a multimeter or a good test light and some wiring tools. Are these items something that you have?

Customer: replied 1 year ago.
I do
Expert:  Charles replied 1 year ago.

Alright, fo the trim, what engine do you have?

is the dash light, one in a gauge or on the dash itself?

Are the switches in the boat lighted?

Ok,

Look at the back of te switches in the dash. Locate the red or orange wire in the center of the switch. Test it for power while the black lead from the meter is hooked to the black wire on the tach. If you are getting power there, test the power on the light receptacles. The gray wire is the hot and the black is the ground.
