well the cart driving when you just put it in gear is a stuck solenoid.......its possible the new one you put in was bad that happens buying new and getting bad....................reverse problem could be just a bad microswitch or the F&R..............voltage thur frame could be several things.........did cart ever have reverse? there are a few smaller cables from F&R that get hooked to batteries and if not right will effect reverse......you really should get a wiring diagram and go over all wires............there should also be a microswitch in v-glide box that activates solenoid so check that but if your solenoid is cracked you want it off cart......new solenoid and check micro inside v-glide....................................
