![]() Something in that range would seem appropriate. I see the relay/contactor is rated at 250 amps. As to tapping for a source of power, I think I'll look for a high-amp rated secondary fuse panel. I'll probably just make things easy, and buy the suggested 'frequently bought together' wireless remote, and spring-loaded switch with it.ĬADpoint, there are two bare-nutted terminals. htmdude57, looking for relays and momentary contact spring-loaded switches last night on the internet, I saw that same relay/contactor. Eureka! One way 'cable-out,' reverse the leads on the winch, and I have 'cable-in.' It works. Taking a leap of faith, I jumped from a well-charged battery, to each of the winch copper studs. ![]() There seems to be enough road maps on the internet to figure out how to wire this.Īs suggested, each circuit stud is insulated from the case, so trying to read from the one stud (or the other) to the winch case gives an 'open' circuit, both ways. If you have an ohm meter, one terminal will ring out to the chassis that is your common, the other terminal should not ring, that's your hot. Lastly, you'll have to determine which you want the use: a toggle switch or a rocker switch almost the same, a toggle is on when appliedĪnd a rocket is sometimes/most times a momentary switch meaning you have to keep pressure on it, more desirable when winching. ![]() The contactor is the relay to use when a circuit must support a heavy current load. The terms solenoid and relay can often be used interchangeably however, in the Automotive market, the term solenoid generally refers to a "metal can" type, whereas a relay typically refers to the standard "cube" style relay. Second, everything I see on wiring diagrams presents the use of a solenoid to be between a switch and the unit. Like the old days would not be a good thing! So just taping off the ignition power might Granted this was due to their wiring BS, but I'm just saying. Now I'm not an active wrencher but I do know I had to buy a special cord for my 2008 silverado just toĪdd a new stereo. Well first you didn't qualify what you're putting this on! You used to be able to find owner's manuals for nearly anything through their online parts site, but it's not that way in this case. One other thing, there's a nylon machine screw in what I assume is the gear case, I suspect this is for adding some type of gear oil/grease? There is another threaded hole opposite where the nylon machine screw is (3 o'clock/9 o'clock, on the third picture), I don't know if that's also supposed to have another nylon screw. My intended use is to pull things into my pick up, or onto a ~4' X 8' open, flat-bed trailer. ![]() Input, please, and thank-you.Īfter I get this squared-away for proper placement of the wires, I'll buy a switch and power cord, and a relay. My concern is, I don't want to short things out, because I have this wrong. Then the two copper threaded studs are used for power-in and power-out, providing 12V + to one or the other of the threaded studs. I suspect it's probably a simple wiring, where the negative should go to somewhere on the winch bracket when the winch is mounted to the vehicle, or wherever it's going to be placed. I tried finding the manual for it on the Sears site, no luck. The Smart Start SBI12 battery isolator is a safe way to charge a dual battery system and should often be installed with a high quality fuse kit.I have an older Sears winch. It features a low standby current draw and sophisticated fault detection and LED indication of operation to warn the user of faults including over-voltage, voltage drop and excessive current draw conditions. It is better than a diode battery isolator due to the voltage drop associated with diode type isolation. The battery isolator is primarily used in 4WD and commercial vehicles and incorporates electronic components that will prevent the solenoid from generating high voltage transients. The SBI2 provides 12 volt DC incorporating 100A of continuous ratings. It will protect the start battery from excessive discharge, whilst allowing the auxiliary battery to supply non-essential loads. The REDARC Smart Start® SBI2 is a microprocessor-controlled battery isolator used in dual battery systems as a solenoid priority system.
