Just getting some of the pics uploaded........
It's hard to believe these are all the same thing isn't it ?
They do it in different ways, but the results the same, forward and reverse control of a series wound winch motor...
And if you're going to have problems, it'll most likely be caused by one of these or the wiring...........

Ah, the near legendary Allbright sealed contactor;

Allbrights have always been "the best" contactor to have, but they certainly moved the goalposts with this beauty.
A few minutes work and they really are totally waterproof and they seemingly last a "lifetime"
Just beware that there are almost perfect copies being used and while good, they're not an Allbright.
If you've got a knackered solenoid, don't bother replacing it, ditch the lot and fit one of these.
It'll be about the last time you ever do and for less than £50 it's well worth it.
Wiring one up as a replacement couldn't be much easier either;
Just disconnect the main live from the battery, remove the wires from the old solenoid pack, sling it in the bin, fit the new Allbright using two of the old solenoid pack screws and reconnect as per the picture.........
You may need to change some of the small signal wire terminals from rings to female spades, but it really couldn't be easier.
You rarely get "fit and forget" these days, except with these.

I've had one problem and it's been with the copies of the Allbright, never a genuine Allbright but check anyway,
Remove the spring washers and check the bolt can bottom out in the threaded hole before fitting.
I've seen some "almost" bottom out and while it feels and looks tight the actual connection is minimal at best, this leads to arcing between the terminal and contact which eventually causes failure.

If this happens, file away the damage on both parts, cut the offending excess threads off the bolt and reconnect properly.
The contactor will have been internally damaged to some extent but it "should" be ok.
