Warn winch 2006 Suzuki Eiger Winch will retract cable but will not extend cable

Hello. It seems the winch on your Yamaha 'strained' its electrical system; 'fried' wires including the 'starter circuit' wiring. It's possible there is a 'blown' relay and/or fuse somewhere. Good luck and keep me informed; if you want to.

Red is POSITIVE.
Connect to + terminal of battery.
Your winch should be equipped with a fuse.
Do not connect to any of your wiring except battery side of solenoid PROVIDED wire is same gauge or bigger (thickness) than winch wire.
Connect Black to frame or negative battery terminal.

Might have corroded battery terminals which would cause the alternator to be loaded from the current demand from the winch that it is killing the engine.

Try cleaning all battery connections and if that doesn't work, your battery may not be able to handle the current surge of the winch due to age.

This winch should simple straight foward hook up. Your big red & black wires should hook straight to your battery. Red (+) black (-) if there is no fuse on the wires put at least a 20 amp.fuse close to your battery. These are the main power suply. They will go in a.small black box. Also coming out of the black box will be the wires that run to the cable in & out switch.and there should be one heavy ga. Wire going to the winch motor. Make sure the wire is good and clean when you hook it to the winch motor. Do not over tighten the nut . Just give a good snuging down. As for your solenoid box. That should be the little black box that your main power wires go into and controle wires come out of..

The vacuum line goes to the smaller of the two fittings on the fuel petcock. Suzuki used a vacuum controlled auto shut off mechanism in many of their fuel petcocks.

wheel bearings , grease your diff too

Maybe wired backwards. Its unwinding when you push the button and does nothing else.. ??

Where did you ground the winch motor? You need a separate, heavy duty, switch with a relay to transfer the positive side voltage properly... DO NOT ground to the battery..use a clean, free of paint, place to ground. You may have fried the solenoid..do not connect the positive side to the solenoid. Direct connection to the + battery from the relay is good with a good waterproof fuse in line. Sometimes I have seen the "maint. free" batteries die when used "wrong" and still show 13 volts+.

could be the pickup coil, the cdi or any of the wiring in between.
