Just seeking some advice on tower lighting. I have a used 2003 VLX with 4 forward facing tower lights that did not work when I bought the boat. Not a huge deal when I bought the boat, at least to me. I got a great deal and that was the only problem then and now and I have had the boat for almost two years.

I have traced the wiring and found that the switch for the 4 55w lights has power. I did find a 15A fuse that was burned out. Without doing the calculation I just blindly put in another 15A fuse and of course it burned out immediately. I then did the calculation (Anps=Watts/Volts) and found that the fuse would have to be a minimum of 20 Amps. I came up with 18.3 amps from the calc.

My question is will a 20 amp fuse work or should it be a 25 amp? And then the more significant question, what size wire should there be for 20 amp and if I need a 25 amp fuse what size wire should that be? The distance from the switch to the tower lights is about 6 feet plus or minus.

The 20amp fuse should be ok. The size wire should be 12 AWG with a 20amp fuse max. If you decide to use a 25amp fuse, you should increase the wire size to 10 AWG (which a 30amp fuse would be ok as well). Don't forget to ensure that the wire between the switch and the power strip or fuse panel is of adequate size as well.

To ensure the 20amp fuse is adequate, just try it quickly. You're only risk is that the wire is two small and it will begin to act like a fuse and heat up... eventually to burn up.... that would be a BAD thing!! So just try it for a few seconds. If the 20amp fuse works... great, then verify you've got at least 12 AWG wire (14 AWG is too small) and you are good to go. If the fuse blows, go to a 25 or 30 amp fuse and 10 AWG wire.

Hope this helps....

Are they the stock lihgts? If not make sure there is a realy installed somewhere along the line, if not you'll burn the switch up.

Johnny,
I noticed you are in California (CA usless that is Canada). Tower lights are pretty much useless in CA. You can't ski at night (legally) and to use them while running will land you a nice ticket as well. The only real use for them is docking at night or moring your boat, but I find a good spotlight works great. Unless you are on a private lake that allows night skiing I would recommend to leave them unhooked. I would even look to remove them and sell them.

Coach-Yea I thought of that but we do have a delta here that I believe that it is ok to run at night on...Besides works good for docking etc. Anyway I have had much fun riding the wake at night.
Chad-thanks for the tips on the wire size. I will check it and give it a shot.
