i have a 97 polaris sl 780 took it out the other day and the battery is no good no more. i bought a new battery installed it. started the motor it was running for a few min, i was watching to make sure it was charging. which it was then the gauges went off and wont turn back on. i checked the two fuses in the electrical box they are both good and other fuses. also some wiring diarams would help
