Motor slow turning over

[oncearacer52]

I have a 2013 ish EZGO with the Kawasaki motor. Motor does not turn over fast enough to start. The ground wire and the wire from the solenoid get hot when trying to start. Solenoid checks out ok but has voltage on both sides but works fine if you unhook the wire going to the starter/generator. The s/g was recently replaced and worked fine for a brief period. It was taken to a shop who said the brushes were in backward (?). I'm leaning toward the s/g having a short. Anybody else have any ideas/ PS the battery voltage drops to 9.6 volts when trying to start and the (new) battery tests out good.
