I ll probably switch out the NSSsince I have a new one handy and that looks like 5 minutes of work... maybe pull the starter and look at bendix if problem returns... btw: dual battery setup is a simple perko switch setup ( just a backup battery basically). Was my first run of the season so I would have been surprised if everything went perfect... thanks for taking the time guys!

Takes less than 1 minute to move one white wire to the other to test the NSS at the transmission. Your call there. Best on the solution. However if your starter is spinning, that is not the issue on the NSS at the transmission. If it were bad, nothing would happen at the turn of the ignition key.

I apologize for the confusion on my part.

Understood, but since it’s sitting there anyway... Thanx again!

On these gen the kill switch interrupts the purple switched power lead. Basically it deenergizes the coil.

For this reason killswitch still will crank on boats with ballast resistors it will often crank and fire then when you release the switch it will dive as the 12V starter feed will also energize the coil via the bypass of the ballast resistor. Newer boats (90+ probably) that have EI crank but won’t fire.

Interesting: I switched to electronic ignition a few years ago (ballast resistor removed)

This will crank with dead kill switch but if only one source of power goes to the coil it will not fire because the only source of power to the coil comes from the ignition switch through the purple wire through the kill switch to the coil. If you eliminated this poorly/bad crimps or whatever you could have a poor start condition - that purple wire must be well connected at all points to feed the coil's draw. On most starter solenoids there are 4 terminals. Battery, starter winding, switched signal from coil and a R terminal. The R terminal is wired to the coil. When cranking the R terminal goes hot which feeds power to the coil bypassing the ballast resistor. When you release the key to run power goes through the ballast resistor to the coil dropping voltage at the points. When talking boat starting symptoms a boat that doesnt crank is a NSS battery wire or starter or key etc. A boat that cranks and won't catch or cranks and pops then dies when you release the key you look at the kill awitch.

I had this happen at the ramp on a super beautiful, calm evening. Frustrating and I didn't figure it out until later. It would run as long as the key was in the start position.

Doesn't that blow? My brother was up at the lake with friends got out the starting fluid drained the battery cranking. Finally called me told him what was up - that + a battery charge and he got it running. But destroyed a whole day of their lake time.
