I found this photo, but it's not great hopefully you can zoom in and will help you

Looks like yellow to the left

Sweet now get it fixed and send it to me. LOL

If you look at the other coils as they turn to be same position they are all on the left

That's right I remember now. I hope this fixes things and she can finally enjoy it fully. You got this

Plus you will now be a master of the dreaded J1 connection

Did you get it working?

Your narrowing it down keep the faith. You can do this!

Have you run diagnostics since replacing the coil to see if it fires?

And you checked power to coil with voltmeter?

Have you tried resetting the mpu. Do the clear function with dip switches then reset to proper switches for Dolly. Instructions are on their web site or I have a paper one if you need. Long shot but odd to me you have power a new tip and a signal isn't happening.

Can you follow the ground wire on the coil to see if it's cut or disconnected. Sounds like that coil isn't attached to the ground buss. I knew you could do this. Your almost there.

Did you also test the wire at the coil black red to where it goes to the board? You said Q10 fired the coil even though it should be Q16 maybe do the same test there.

Either way your right if by jumpering the board and coil fired the wires should be ok and it's the TIP that is not functional

Alltek will also replace your board at a discounted price. But you have come this far and you have done a rectifier board so this should be simple. Then you can stand back and be proud as you watch your wife enjoy her pin.

And to Quench with all the good information and the pics with the stuff written on them was top notch.

Do all the targets register a hit then producing a signal to reset?

I'm still feeling like it's a signal thing. But I don't know which wire and there is no chip on the new boards. I'm just an apprentice at this stuff hopefully a journeyman like Quench chimes in.

After everything proved I would think it's got to be a signal issue

Maybe push or reset the chips or one got damaged with the voltage. Unfortunately past my level

So now with all you have done does the coil work in diagnostic test?

I don't think he did it after continuity fix.

Get a new coil if it locked on too long. Send your board back to Alltek and it is a fraction of cost for a new one.

In fact get a new coil
