Tach and charging system works again!

I noticed the tach wasn't working and the voltmeter was getting to just barely under 12v. From all the internet support forums, both of these symptoms were related to a bad engine speed sensor. After installing this product, both issues were resolved. Be sure to gap it correctly.

I dropped the sensor, so either I broke it, or it shipped defective
