Should my winch work with engine off??
I have a Smittybilt XRC8 Winch (not so great). It does not work with the engine off. I have a BenchMark Dual Battery K.I.S.S. kit installed (great product) and Optima YellowTops. I understand the winch creates a big amp and voltage draw but even with the key on and two Optima batteries in parallel all I get is a slight clicking sound from the winch. With the engine running and the alternator buzzing the winch works just fine. So is that normal or do you guys find your winch will work without the engine running?

My winch works without the engine running but I only run it for a second or two to let some cable out before I free spool. then I turn onthe engine and get my RPMS up when under load.
Not sure why it isnt working, may be you need a new battery, not sure.

Yea I understand it would kill a battery in short order and its a crapping idea to winch without the engine running. The only times I have needed to so far I have used it with the AEV ProCal and had the vehicle idling at 2500, but I do some river crossing from time to time and if I ever stall it out I like the idea of being able to pull the vehicle out of the water even if it costs me both batteries.

The winch is wired direct to the auxillary battery. The KISS kit has a very simple solenoid that switches on with the key is in the on position to hook the batteries up in parallel. So it really shouldn't matter if the key is on or off the winch is always hard wired to at least one battery. Sounds like some winches will run for at least sometime on just the battery. Mine does not and never has.

Even though you turn the key on, my understanding of the Benchmark system is that it does not parallel the batteries until system voltage reaches 13.1(?) VDC. Your JK will only reach this voltage when the engine is running, the alternator is charging and the starter battery has been recharged. This should only take a minute or two after the engine starts. If the start battery has been drained by something this will take longer for the Benchmark to parallel.
Which battery are you connected to? Starter or Auxiliary?

That's funny, yea I use the batteries alot more then the winch. Anyhow guys this is not about the batteries or the BenchMark kit. The KISS kit is very simple and that what I like about it. With the key off the batteries are isolated and with the key on the batteries run in parallel. I think Benchmark makes a SMART kit that monitors the voltage and switches off and on based on that but not the KISS kit. I wonder if the winch is designed to "look" for higher voltage that indicates the alternator is running before a soleniod will engage the electric motor. That what it seems like but I bet the solenoid is more likely just failing.
