Start/kill switches and Starter hookup

[HONEYBADGERFTW]

Briggs V twin Vanguard. I’m not sure if I can, but I would like to have a push button start switch (2 wire if possible since I have a switch that is that), and a separate kill switch (two terminal latching push button). Problem is I have no clue how to accomplish that. So if someone who is knowledgeable that can help. And everything is just set in place for the picture, I still have modifications to do for engine installation etc.

1- Negative battery cable
2- Positive battery cable
3- Two thin wires coming from underneath the shroud
4- Wire coming from an electrical block that has two yellow wires going underneath the shroud
5- From starter solenoid where the + battery cable is connected as well
6- Wire from battery + cable (went to the old “key switch” I believe )
The green ⭕️ Is where a ground goes from the starter to body/engine mount/grounding point I think?

I’ve looked for an understandable diagram oft video but have not found anything

You need to post your engines model, type and code numbers; so we can select the correct wiring diagram to help you.

This youtube video shows where those numbers are located on Briggs V-twin engines: https://www.youtube.com/watch?time_continue=121&v=pJse_XQrO4Y

Ok I’ll have to look when I get off work

 

[HONEYBADGERFTW]

Model number 350447
Type 1096-E1
Code 97111911

That help?

Ok, well I guess I’ll have to just try a 5 or 6 pin switch instead lol.

Im sorry you not getting any replies... these big V-twin Honda/Predator and Briggs engines are not quite that prevalent here on this forum... Only a few have them...

 

[HONEYBADGERFTW]

Yeah I’m just frustrated because it seems like it’s something simple but I can’t figure it out lol. I got this engine from a trade and know nothing about how it is supposed to be hooked up because there were some “it’ll work “ type fixes on it. The schematics I can find are generic or really confusing to me. This project has turned into one obstacle after another, so surely when I finally get it done it’ll be awesome ��

Maybe send Anderkart a PM. He doesn't check the forum regularly, so a PM regarding the engine numbers he asked for might help you out more

"3- Two thin wires coming from underneath the shroud"

The wiring diagrams indicate that one (or possibly both) of these 2 black wires connect to your magneto and are used for the kill switch. If that's correct, you should get spark to start the engine with both of these wires completely disconnected; then you should discover that grounding one (or both) of these wires will kill spark to shut the engine off. If your testing confirms this, you could connect one (or both) of these black wires to either terminal of your two terminal latching push button switch; and then you'd just need to wire the other terminal of this switch to ground.

"The green ⭕️ Is where a ground goes from the starter to body/engine mount/grounding point I think"?

Nope that's not a ground, that terminal activates your starter solenoid. Your push button start switch should work fine, it just needs to send power to this terminal to activate the solenoid; then your solenoid should send power along to the starter through the battery cables.

Awesome!
So + battery to one side push switch and the other side of push switch to the terminal that activates solenoid. Solenoid has a +battery connection to one side, other side goes to starter. Both the solenoid and starter are grounded via bonding/connected to the engine. Correct?

What is wire #4? And where does it go?

 

[HONEYBADGERFTW]

Added pictures of solenoid/starter wires as they were hooked up, I haven’t messed with them yet.

#4 goes to battery positive to charge battery.

Yes, yes & yes.

I agree with cleatusj, your wire #4 is the output from your charging coil and voltage regulator. It needs to be connected to + battery.

You guys are awesome, thanks for your help and patience!

Your welcome.

Something else you should do is install two 15-amp inline fuses to protect things in case of a short.

I'd install both fuses at the starter solenoid post along with the positive cable that goes to your battery. Then connect one of the inline fuses to your #4 wire, and connect the other fuse to the wire that's supplying power to your push button start switch.

I'd use 12 or 14 gauge wire to hook up your push button start switch.

ATO fuse holders are available at most any auto parts store:
