Anyone working on their bike, from newbies to seasoned mechanics, can benefit from his more than 800 video lessons on mechanical, electrical, safety, business, and mentorship.

Electrical problems are the worst nightmare for many of us who work on our own bikes. They can be hard to isolate and may show up intermittently, making them a challenge to chase down. Ignition problems can stem from plenty of causes, but the easiest and best place to start looking is the spark plugs. First, a little background on how the spark plug cap attaches the spark plug. Example of a failed spark plug cap up close.

Next up, an easy way to check the spark plug wires.

Keep Wrenching,
