Hello, I just joined this site, I have 3 bombardier golf carts, one now has a gas honda 125 motor with a 5 speed ,and the other 2 still have electric, 1 has a contractor fault problem in the controller,still working on that one.
About your range problem and cluster display. I have found that you may be able to reset the cluster by removing the 40 amp fuse and then put it back.Make sure your battery's are fully charged before doing this. The fuse is on the pos side of the auxiliary battery. I have cut a 6" by 8" long hole in all my carts to gain access to the aux battery. If you deside to cut the hole just be carefull not to cut the wiring, it runs alone the side of the tunnel, stay 1 1/2 " in from the side of the tunnel. I could send you some pictures if needed.
