“I’m so excited to share what the last 20 years of my life were made of! It has been an awesome journey so far and so much happened it was almost impossible to remember it all!! You all know a lot about us but there is SO much more we never said and showed before, now the time is right to do it. Our backstages and living rooms will open up for you all… you’re welcome, coilers, come in and get comfortable…
Once upon a time…”

As shown in the failed coil video below we are also see a failure in the plastic tube housing.  The secondary coil is putting out more than 60,000 volts and the plastic tube (inside the metal tube) is the insulator.  We've seen multiple coils develop a small crack in the plastic and of course its arcs/grounds out on the metal tube.  This type of failure will definitely trigger a misfire code. The misfire code is the end final result of what has transpired through the ignition cycle.  There are lots of variables and possibilities of what can go wrong...... A short to ground through the coil can ruin several components on the printed circuit board.   The MOSFET transistors on the coil packs act as electronic switches turning the spark plugs on and off.  They can handle up to 1,700 volts at 4 amps which is pretty considerable considering their small size.  Each spark plug has its on controlling MOSFET.  There is a secondary set of MOSFET's and these act as master switches for both the A and B channels of the ignition circuit and work in pairs on three cylinders (1-3, 4-6, 7-9 and 10-12).  These parts can fail by simply becoming dysfunctional.  They can also fail from getting fried as the result of a direct short at the coils which will draw too much power from the VT/ICU.  The VT/ICU can generate as much as 10 amps output which can totally overwhelm the 4 amp capacity of the MOSFET's controlling the ignition coils. Not only can this power surge destroy the MOSFET transistors but will also blow out diodes and zener diodes that are in the ignition circuit. This is why its so important that the people rebuilding your coil pack clearly understand what's involved in troubleshooting and resolving all of your pack's potential problems.
