The only thing in the black box is three pairs of diodes, connected as "or" gates.

The box incorporates the "input adapter" and "output adapter", shown in the old installation diagram: http://www.jandssafeguard.com/MaximaDrawing3.gif

It's possible I put one of the diodes in backwards. That's easy enough to verify with your DVM set to "diode check".

If that checks out, I suspect you miss wired it. Make sure that you actually picked the six coil wires, then double check the order.

Hey John. Any update on my unit. Last I heard from you was that you were goinig to send it back to me on this lastmonday and I have tried to call and have emailed a few times with no response from you.

Gabe: Had to unplug the phone to work on orders. Your unit shipped yesterday. I'll email the tracking number.

Did you get the engine running in waste spark mode before the coils burned? Just want to make sure that you had it wired correctly, so you don't blow them again. We've had 350z customers blow coils because of miswires.

 

If you mean...did I just plug the jumpers together and start it. Yes, both when I did the original install to confirm that it was done right and now to be able to drive the car.
I have not boosted in the last couple of weeks (since I sent you the unit) and it has run perfect.

I hope that is what you mean.

 

dam ,sorry to hear that. was the J&S installed at the time or is this just mechanical failure from worn parts.

 

it was mechanical after the detontaion i was having all this year
