3.0. I just jumpered bat and purple and it started ran fine but key would not turn off. I had to disconnect purple then hit kill switch. This isn't my work I got it like this
Dunno what was hooked up when you jumped it, but if purple isn't getting power, ignition shouldn't be powered and should shut off. Did you check your old switch or just replaced it? And yes, that new switch is wrong.
Thanks for the input guys. I'm enjoying working on boat and learning as I go. I will order right switch. So basically the purple wire needs to be shorted to ground. I have another question. Where does the voltage come from to put 12 volts on that line? I don't see it coming directly from battery just to the alternator. So the alternator puts out the 12 v?
NO :nono:
That wire supplies 12V to the motor when the key is turned ON. Short that to ground and you blow fuses or other things. The key switch you bought is for a 2 cycle outboard. The OB disconnects a ground from the magneto to start and run, then grounds the magneto to stop the motor.
Your I/O works like this
The red/purple wire has 12V from the motor to the key
The Purple wire supplys 12V to power gauges and motor
The Yellow/Red wire supplies 12V to the slave relay to start the motor
I appreciate your explanation alldodge. So when key is turned from run to off does it open a 12 v circuit if so which one? Color wire? Or does it provide a ground somewhere. Bare with me here. Im learning. I have the schematic for circuit if you want to reference that.
Im hoping you guys can help here. This is a wiring job someone else did. So I got home . This 3.0 has the e.s.t. ignition in it. I did what you said and here's what I got. I ohmed switch turns out good. So I go back to my coil... Running into distributor and took a d.c. voltage on that big post and got 12 v dc. So there's a hot connected in there feeding it? I unplugged to coil and on the purplish color wire I have 12 v there so I have to chase that wire?
