Hi all. Was under way yesterday and the port engine just dies. Fired back up several times now it just won’t do anything. It’ll crank over good, just nothing. Checked the gas, it’s good and get into the carb. Swapped coils from starboard to port, nothing. Port coil runs the SB engine. Swapped Thunderbolt boxes, nothing. Port Thunderbolt box runs the SB engine. Got 13 volts to both terminals on coil, no spark coming out of the coil wire. Both coils are good as they both run the SB engine. Ignition terminals in the fuse box have power, the terminals at the key switch have power as does the ign breaker. Has 12v at the terminals on the coil while cranking it, just no spark coming out of the coil wire. Even swapped those out too. I’m stumped. Anything else to look for?
