hey guys, i was recently givin a 2000 seadoo islandia with the merc 240 efi. now heres where im having trouble with the thing. first off. he has a big stereo in the boat. has 2 6v batteries in series and also 1 12v for the main power to the boat. but the main battery does not have a ground wire connected to it. the ground wire is connected to the 6v batteries. so i put the jumper to the pos term of the 12v battery and a ground on the motor. everything powers up engine turns over fine but no spark on all cyl, and aso theres a relay ticking when i turn the key on, its on the side of the motor, so what all do i need to check for on the no start and aslo what to do about the main battery neg cable
