Stern spike 2 switch problem

[Markedkiller78]

I am as new to this as can be, so any help or advice would be gratefully appreciated.

The lil Deadpool bash toy isn’t registering hits, from what I can see, the leaf switch making contact when pressed, but the switch test always has an “x” I tried bridging the pins on the black/red + white/brown wire, but no change.

Traced it back to the CN12 connector and it looks well seated.

Any idea what to try next?

It's usually a bad crimp inside the connector that plugs into the node board. Try fiddling with that and ideally re-crimp it.

Does that “x” mean the switch is activated / closed?

What Fubar said. These issues are becoming pretty common on spike 2 machines.

Turns out it was a combination of the crimp and the quick disconnect in the pic

It took me hours as I knocked out a different bank of optos pulling at wires, that one had a 3 snapped pins, ground being the one that knocked the lot out.

Good news is, everything is working now

Does anyone know the part number for the connectors / pins, I’ve got a few I’d like to replace already

Sounds like the pins.

You will need the following toools if you don't have them:

1) these to pop the pins out of the housing or you can use a tiny screw driver

2) Pins:

I would get more than you need by at least 15. You will need a couple to practice

3) a crimp tool

4) Wire Strippers

5) Wire cutters

6) some spare wire to practice (if you need) I didnt

You need to do the following:


1) Take pictures of the housing and pins, plugged into the node board (so you know which pin goes where)

2) remove the pin causing the problem. To do this disconect the connector from the board. gently push the spiky tool or a small screwdriver in the hole slightly above the block furthest away from the wire. its metal and long for each pin. gently pull the wire at the same time. the pin will pop out.

3) Using the wire cutters cut the metal pin off. Just above the metal crimp bit, it will only cut around 1/2 centemeter of wire if that!


4) Take a pin and practive crimping it in the hole furthest away from the handle, the top one. Its a short very quick action. Once you got the hang of it..

5) measure the wire with the crimp so you cut the right amount. put the uncut wire in the crimp housing, should be just enough to cover the metal bit that u shapped.


6) using the wire stripper, placce the wire in the smallest hole, cut teh wire to the correct length the wire based upon the length measured


7) place the pin in the crimping tool, whilst the pin in the tool, put the wire in and then press the handle to crmip, fast hard and quick. Pin should be now on the wire.


8) push the pin back into the housing, will here it click. ready to go, plug the conector back in.

Thanks for the incredibly detailed reply

The circled bit was already snapped off 3 on the pins causing me issues. I’ll get some ordered and replace them

Your welcome yep that's where it normally snaps, when I first encountered this I was going down a rabbit hole that it was something else
