Hdk electric cart won't run

[Scott harland]

Hi everyone brand new to this sight but will try my best to learn what's up. Got a 2011 hdk cart that doesn't start. About a year ago changed the pod censer or throttle censer. Found issues with the wire connecter and bypassed the plug with three of the five wires. Ran great for the last year and a half. Went to put water in my battery's and it wouldn't start. Checked the wires at the bypassed connector and found one of the wires pulled out of the barrel splicers. Repaired connection and pushed the accelerater and she moved. Taped it all up and wire tied it to the frame. Nothing. Undid everything and cut out plug entirely direct wired all five wires still nothing. Don't know where to go from here. If anybody's got any ideas that would greatly appreciate the help thank you in advance. Scott Harland.
