Default Motor slow turning over

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.

Is it an OEM starter/generator or an aftermarket?

Aftermarket S/G are very poor quality and fail quickly after replacement. Do you still have the original OEM part? Usually they just need a new set of brushes ($30) and are good to go

Hot wires means high resistance somewhere. It's dragging the battery down to look like a failed load test.
Try bypassing the positive battery cable to the solenoid. It could have hidden corrosion in there.

Different S/G on these than those with the Robbins. Lots of problems before I left at the golf course on these.
We were told to replace the solenoid and S/G end plate with new brushes. I have also read where you can install a smaller pulley on those. EZGO didn't get these things quite right back then. I think maybe if EZGO would install a Automatic Compression Release then the issue would go away but what do I know.

I never seen the ground issues on these we had on the Robbins but like cart around said it does have high resistance somewhere.

Does it with the spark plug out also. Not my cart but it appears to be an after market item.

Just put it in a vice and put 200 amps to it and it spins like crazy. Cant tell about the torque but, now I am not at all sure about the S/G. I also checked the 12v supply wire and the ground and got 12.5 volts with the s/g out. Was getting 9.6 with it hooked up.

The dynamo starter/generators suck. Most dont even last a month before they either short out or eat themselves and create a huge mess internally. Very common aftermarket replacements on the club cars who has used Kawasaki motors pretty much forever...

Get an OEM one and you'll be good for a very long time to come.

I dont know why ezgo and club car didnt go with the ACR camshaft. Would be so much easier to start. Look through the ckub car forum the amount if members whose carts they have to hold the gas pedal for 5 seconds or so to start it when the engine stops on the compression stroke, because the S/G has a hard time overcoming it. I've always wondered if the ACR camshaft would be compatible
