Push Button Start Mod - It works! With video and full instructions

Can you refer me to which ones those are?

Here is one option. XINY 12V 2-way low-level solid state relay modules solid state relays with fuse 240V... https://www.amazon.com/dp/B01FZ6NI0W/ref=cm_sw_r_sms_c_api_GX3xzbRQC73G3

Really weird, I went through and soldered all connections except the wires that hook up to the key switches where I used T tap connectors. I triple checked the crimps and all looks good. I used cheap relays from amazon, could that be the problem? stumped!

Since we are using a high level trigger to charge a coil that pulls in to supply a ground you are likley hearing coil feedback into your electrical system. This is common in this configuration but what gets me is that it is loud. Could certainly be the cheapo relays. You could try the ones I mentioned above as the trigger is fully isolated this way and there is no coil

I did go to Advanced Auto and bought 2 different brand Bosch style relays and it didn't make a difference, weird think is the pop is through the speakers of my stereo, turn the volume all the way down pop cannot be heard. I have bought a better 4ga ground wire for my amps I am going to run this weekend and I want to see If that makes any difference.

I do get a soft pop through my speakers. That pop is the electromagnetic coil in the relay feeding back through the ground. A loud pop would be bad though. Soild state relays should solve that issue.

So I take it you only need 1 of the 2 way solid state relays to replace the 2 Bosch relays. If so what is the wiring diagram for that? Looks Nice!

 

[Mainah]

Those are two isolated coil type relays on one board in that photo. The key here being that the power supply for the coils is isolated from the trigger and output. This will work nearly the same as solid state.

I got my solid state relay but I am not sure of the wiring, It did not come with a diagram. Any help would be appreciated!

 

[Mainah]

DC+ = +12vdc
DC- = ground
Ch1 = trigger for relay 1
Ch2 = trigger for relay 2

The terminals on the other side are the ones that are connected when triggered

Any reason why you went with the traditional relays instead of the solid state ones? I'm getting my shopping list ready for winter mods, and push-button start is on the list. This is a great thread and an awesome how-to.

I had the bosch style relays on hand.

 

[Bluewater272]

Well, that's certainly a good reason

For those of you thinking of this mod, this is the wire harness that connects to the very nice buttons that Mainah selected. Saves you some trouble of having to solder to those tiny connections.

I still have all these parts from last summer that I never got around to. Might as well order these and hope I get the balls to try it out.

 

[Bluewater272]

Should make it a lot easier to install. Can do 95% of it off the boat, then just hook up the two wires to each ignition harness.

 

[FloJet]

Interesting

 

[Nick Hughes]

So theres 5 wires on the back of these switches, which 2 are used on each switch? And looks like on the relays, all 4 wires but the 87A on both are used? Not an electrical engineer so double checking.

 

[Mainah]

Not recalling the wxcat layout of the switch I used but my guess is that there are 3 leads grouped together with a com(common) post in the middle and flanked by NO(normally open) and NC(normally closed) leads. When the switch is not pressed the NC and Com leads are connected. When the switch is pressed the NC lead is disconnected from the com lead and the no lead is then connected to it. You will want the the NO and com leads.

The other two are likely the +12vdc and -—12vdc for the lighted ring which should be connected to key on and ground.

Hope that helps.

Just looked at my pdf wiring diagram. I should edit that to incled no and com. For now the the yellow trace from my diagram goes to NO and the purple trace goes to COM for the start button. For the stop buttom the yellow trace goes to NO and the brown trace goes to COM.

If the buttons have the led light ring jump the NO lead to the +12 vdc lead and add a wire to ground for the -12vdc lead.
