I have a unit that is blowing the lift fuse during normal operation. The mast is not in a bind, bearings are in fair condition, pressures check out OK and no excessive grounds found. Current draws recorded during normal operation with/without a load and also recorded with with manual lower open. All access modules have been changed, software has been updated, lift motor has been changed, line contactor replaced, buss bars replaced and cable lugs replaced.

Has anyone seen a similar problem? Any suggestions?
