Well looks like it was down to "power" I have just retested it. Had no time till now as I was working!!
Anyway, with the main battery it would just move a 110 with the brakes on. When linked with the 3rd battery it pulled it fine, this was with the top layer on the drum. It would move it along dryish concrate ok. So it proves one other thing, my LC is heaver that a 110 as his moved and mine did not.
So it all comes down to I was "well stuck" .
So time to get a new main battery
Thanks for all the help. I think I might change the winch anyway for a bigger one.
