See full version: What does carbon tracking look like
Spark plug carbon track. A common source for a misfire is arcing in the spark plug boot. Air can ionize and become more conductive. This can cause an arc adjacent to the spark plug insulator and eventual carbon tracking that makes the progression of the failure get worse.
Furthermore, what is carbon tracking distributor cap? Cracks. If any cracks are present on the distributor cap then replacement of the part is required. Carbon tracking. Carbon tracking indicates that the high-voltage of electricity has found a low-resistance conductive path over or through the plastic. The result is a cylinder that fires at the wrong time, or a misfire.
When a coil fails, it is possible the electricity created is unable to reach its destination, the spark plug. This path is commonly found through the boot or body of the coil. Carbon tracking happens when oil, dirt, or moisture is electrostatically attached to the boot or insulator and creates a path to ground. here
Connect black LED wire to the GRY (or BLK/GRY) wire of the ignition coil's wiring harness connector.
Disconnect the ignition coil from its electrical connector.
Connect red LED wire to the dark green with orange stripe (DK GRN/ORG) wire of the ignition coil's wiring harness connector.
CASE 1: The LED flashed ON and OFF. This is the correct test result. more
The coil output will look for the easiest path to ground, if everything is in good condition, the easiest path is the tip of the spark plug. In your case (with the coil lead disconnected) it found it through imperfections in the tower. No mystery here, just electrics 101 <br /><br />Aldo
Thanks again Don. So i'm not sure now. Should it be arcing? I'll remember to ground the coil in the future.<br /><br />Hey Don, I may not know much about boats but if you ever have computer questions let me know. I also know a bit about 4runners.
Ok should I buy a new coil?
Clean it, look at it. Any cracks? If the answer is no then your good to go. If it's cracked, replace it.<br /><br />In reality, it's a sign of a strong coil and correctly operating ignition circuit.<br /><br />Aldo more
On the slightly less favorable (yet totally tolerable) side, the Race Face 780mm alloy handlebar and 40mm stem proved a little harsh for my liking. This was particularly evident after riding the OneUp carbon bar for a season. Also, the stock WTB Silverado Pro saddle was swapped out after one ride for a platform that better fits my butt. [links]
I flipped the hi/low flip-chip into the “high” setting for a lap, but on the trails I rode it didn’t make sense. The BB isn’t too low with a 29mm drop, and the slack headtube angle is better to stay that way. That stated, this headtube angle is rather slack, and if I regularly rode less steep stuff I would be happy that the engineers thought of me. This bike represents one instance where I feel the geometry adjustment options are warranted.
All but two of the latest Santa Cruz mountain bike models use their VPP lower link suspension design, and for good reason. While I will dig into the ride sensations shortly, I can say that this platform has some unique qualities that set it apart from the competition. It feels as supportive on technical climbs as it does loose descents, the platform doesn’t require fancy shock tunes and works with coil or air-sprung shocks, and it has an overall feeling of durability — in just the way you want a suspension platform to feel on a bike that’s designed to hit thousands of square edges and bounce back for more. more
The flipside of that extra shock resistance is that the bike pops back with a force when you ask nicely. If you hit a compression, or make one, and you want the bike to follow you off the ground, it will comply. With the appropriate rider input, the Megatower will pop and play on trail features like some smaller 29″ trail bikes. That playfulness isn’t for free. This bike seems more planted than bouncy, and it took me a ride or two to determine how much I needed to push down in order to achieve loft. With that sorted out I was largely able to put it where I wanted without much thought or hesitation.
So, let’s get this thing to the top of some trails. I climbed the hills behind my apartment for a number of weeks before taking the Megatower to La Thuile for chairlift laps, and the bike put an ascent smile on my face. Similarly to the Yeti SB150, you can climb on this bike with the shock’s compression switch flipped all the way open. There’s no notable pedal bob, and the rear tire maintains traction without eating up all the calories you inhaled at breakfast. The platform feels super supportive, and at my weight of 68kg (150lbs) the difference between climbing with the compression circuit open or closed is minimal. For reference, the shock comes with a 450lb spring on the size medium, which was plenty supportive for my weight. [links]
