I have a 2006 RXT Supercharged. It started out recently having the P0562 error/low voltage. It would be slow to turn, then not turn and I'd have to charge it and it would start to work again for a short time. Eventually new problems arose, the speedometer would jump all over the place while driving, the engine would randomly cut for a split second full throttle and then the speedometer just stuck at 0. Now it won't start without a jump or a charge, just quietly clicks. I changed the battery, used jumper cables to bridge the negative terminal wire but that didn't fix it. I'm not terribly savvy and would love some direction. Or if anyone knows a good mechanic in Maine. Thanks!
