Warn 8274 winch

Hey guys, Im over from the normal XJ section. I just bought a used warn 8274, duhh, and am having some issues. It can with the 4 solenoids already wired from the last guy. He said it worked before he had it in storage for 2 years. I found a wiring diagram and it all looked right. This morning I hooked it up using jumper cables to test it, clamping the + to the + lean and grounding from the battery to the winch case. Pressing the controller buttons did nothing. I could hear and feel the solenoids click as they should, just no movement or sound from the motor. There is continuity through the motor. Any ideas what could be the issue? This is the wiring diagram i followed since I have the 4 solenoids Thanks for the help guys

Tried jumping the motor straight to a battery to eliminate the wiring and solenoids?

I used the cables to clamp to the positive lead going into the solenoids and the ground clamp to the case. That didn't work. I tried clamping the jumper cable right from the battery to the motor lugs and there was no movement or sound from the motor.

the motor does turn by hand. Iv never turned another winch motor by hand so I don't really know how hard it should be but it takes some good effort to turn it while engaged. The clutch does disengage and allows it to spin really easy

It should be pretty hard to turn the spool by hand with the clutch engaged since you're actually turning the motor through the gears. Since the driving force of your hand is moving backwards through the gearing, your efforts are actually being reduced instead of magnified like the motor power is when moving through the gears in the other direction. With the clutch disengaged from the gears, all you're spinning is the spool. It sounds like you may indeed have a good winch there.

Check out this thread for lots of great info. > Warn 8274 rebuild
Post 149 explains that the control coil grounds through the solenoid casing so no control ground wire should be needed, but older winches can develop oxidized ground paths and benefit from a ground wire added to the unused control terminal(s).
You can lightly test a soleniod by running a temporary ground to the not-connected control terminal (since the case isn't grounded when the assembly is out of the winch) and a +12VDC signal to the other and listening for the click of contacts engaging. You should read minimal resistance across the primary power terminals when the coil is engaged.

May need new brushes, or just a thorough internal cleaning...
- If you take the brushes our EXPECT them to fly across the room
hint: put the whole motor in a white garbage bag before disassembly, then you'll know where the springs pins and washers went.

I did my old Kirby vacuum, about the same size motor -anyway, works great now
