Anchor light wireing for hurrcane deck boat

If it's near the bow then it's the drain for the anchor locker. If it's near the stern then it's the bilge pump outlet.

Look for loose or broken wiring connections. Swap front and rear speakers wires at radio and determine if problem is the radio or the speaker system.

Well if the display is damaged, it's a boat anchor.

With it connected to the amp remove the wires to the cartridge. With the amp on touch each wire with your finger one at a time. On one wire you should hear a loud buzz on the left. On other wire the right. The two other might produce a minor buzz or nothing at all, so ignore them. If you hear the buzz on both channels there's something wrong with the cartridge or the connection to it.

If you don't hear the buzz. Then (1) there's a bad connection between the deck and amp (phono plug or wire). (2) failed pre-amp inside the record deck itself. (3) failed pre-amp in the main amp. (this would not affect any other settings in the amp so tape decks will play normal etc).

Make sure the remote wire is hooked up. You can run a small wire from the power terminal to the remote terminal. If it powers up, then you have a remote wire problem. You can run a remote wire from the blue power antennae wire of the deck.

the reason for the 3' min. on your ground cable is that interference is picked up with longer gound cables. Especially if it passes close to any electrical components, e.g. spark plugs, capacitors, anything with electrical current. These signals are amplified within the amp. (because this is what amps do) and distributed to your speakers. you could try a noise filter / noise suppressor but I've never had luck with those. You could also try finding a metal part of the frame (if there are any) and attach your ground to a bolt along that frame and if your more advanced you could create a hole and use a screw to tighten the ground to the frame. Small note to that, boats create a lot of vibration so use a ground screw with a sort of tooth like seration at the head that grips as it tightens (so it won't come lose). If you have an extra battery you may want to attach the amp directly to an independant power source to see if your getting the same hum. A direct short in your electrical system will create the same sounds. A bad ground your electrical system will do this also. You may also want to check you high and low band pass frequencies if applicable. Set them to high and you'll get a hum. I would start there adjusting them down or setting them to the center and adjust accordingly if this stops the hum. I'm running 4200 watts all together and if I adjust to high I get interference just from the force of the amp itself. Good luck. Hate electrical problems on vehicles, too many wires.

I have two deckhand anchor units. I ve tested both on battery, and both went up. I replaced switches, and I get nothing, but I heard a light click coming from unit. Is the motor bad?

Is this the main fuse???
600watts motor on a 12V system drops 50amps...
You should have an 80 or even 100 amps fuse for the power cables!

3 terminals.. 1 power input & 2 x outputs

Main positive goes to 1 terminal = power in to switch.

The anchor goes to another terminal = power out from switch to anchor

3rd terminal is another output for lights/anchor.
