how to repair a voltage rectifier regulator charging system

In this video, I probably demonstrate a method to troubleshoot and repair a 12 volt charging system’s voltage rectifier regulator. Many cars, trucks and motorcycles have them and they are easy to fix if you can find rectifier shims and micro collider rings.

My prototype DIY 10A rectifier diode voltage reduced four series 4S li ion battery charger circuit

I don’t want to charge four series (4S) lithium ion batteries to 16.8V (each expected to reach 4.2V for a total of 16.8V), in case they end up with uneven voltages (one/some more than 4.2V and some less than 4.2V). Since many chargers are not adjustable and are therefor set to charge to about 16.8V, I came up with this connector system that use a 10 amp rectifier diode to drop about 0.7V from the charger. for links to where I bought most of the things I use in my videos.
