2005 48V Club Car issues (help!) newbie

[freemurray]

So I purchased a 2005 Club Car DS from someone and the batteries were bad. I replaced all 6 batteries with NEW Trojans. The cart at take off seems fast but doesnt feel like to goes thru all the gears if you know what I mean. The top end sucks! My dad has a 2001 Club Car and runs off leaving me behind.

Now there is a white wire coming off the solenoid that I was not sure where it went. It would not move tho until I connected it to the power on one of the batteries...

There is also a blue wire dangling not sure where it goes either... thanks guys, any help would be greatly appreciated...

I have called myself looking at a wiring diagram (from a manual I found online) but still cannot figure it out..

I also think the brakes may be sticking a little. Reason I say this is because in tow it is very hard to push...even when the batteries were out of it

so I figured it out... the blue and white wire that was dangling went to the left side of the sylenoid... that white wire was not suppose to be there

and my speed sensor was bad. the magnet had a slight crack in it.... its good and fast now...no limp mode
