Having installed a Milemarker H12 we set out to test it on a hill.
Uphill went fine, no funny noises and a nice steady pull in low gear.
Upon reversing however, the winch screamed at us, the speed varied quite a bit between 2x and 4x the uphill speed, with a period of say one meter of cable, as if the winch alternated between freespooling and providing some resistance.
What could be wrong?
