in my 88 js550 I have a new battery, well the first battery on this ski, anyway the battery has 11.5 volts and as soon as I hook up the Neg lead it instantly drops to 5 volts what can pull that much voltage? I pulled the ebox and it all looked cool everything hooked up and pretty clean (except for the rev limiter wires). I started the ski the first time on the battery fine and then next day it was stone dead and after a charge it would barly turn it over now it just clicks the solenoid.
