Total Loss Kill Switch.

[Shifty]

I may be going to total loss here soon and want to eliminate as many switches as possible.

I talked to MSD and they told it is safe to kill the ignition by cutting power to the violet wire. It is not required that you use the pink wire to ground the system out. I really like the idea of only having to momentarily touch the kill swith to stop the motor. I also like the idea of energizing the MSD simotaniously with the start button.

I drew up a ghetto schematic of what I think would work, let me know if you see any reason this would not work.

I would be using waterproof relays of course, maybe even "custom" potted.

Well now I need to figure this out, I made the leap and bought a Dual Digital TL.

Where are all the Electrical Gurus?

Also, can anyone tell me what type of coil backet comes with the kit? I would like to mount them on the battery and wonder if the supplied bracket will work for this.

Call John at Jet Ski Solutions.

I will be buying my battery wires from there, I think he would need to see the schematic himself to determine if it will perform.

you will need a latching relay and 1 regular . and switch both the start stop and start buttons to a negative trigger. so that when you push the start button it will activate the start solenoid and the latched relay, and when you push the stop button it un latches the relay killing power to the coil and trigger

That is pretty neat, seems like I remember seeing something like this but couldn't put my finger on it. I think I could get it reduced to one relay and a diode this way.

Thank alot for the pointer,

I tried the same thing until I realized that the kill switch works opposite of what I wanted (aka only continuous when the lanyard is disconnected). I know you were originally trying to make things simpler with fewer parts to go wrong but now you're talking about adding a relay and a diode instead of a simple waterproof switch. That adds more parts and makes it even more difficult to troubleshoot when (not if) something goes wrong.

Just splice the stop switch wires into the pickup trigger wires like the instructions say. Then if the switch really bothers you, just splice the wires together (always on), add shrink wrap, and disconnect the battery at the end of the day. That way everything is hard wired and sealed.

I will only be running in fresh water and am really anal:frown: about quility solder joints, etc. I would only be adding a diode and relay, I would end up encapsulating these two connection in potting compound with a pigtail of 5 wires coming out. All of those wires would be soldered with adhesive heatshrink.

If I am seeing this right, I should be able to hit start this would simotaniously powering up the TL Brain and crank the ski, the whole system could then be powered down by one brief touch of the stop botton or of course the lanyard.


I will get my TL in next week and play with it.

Well I wish you the best of luck then. Electronics is not my specialty so if you think you can make it work, I won't go against you. Let us know how it turns out though.
