Using a MOSFET to Switch High Current Automotive Loads (Part 4): Build a Diesel Glow Plug Controller

MOSFETS beat relays when it comes to switching speed, and with modern components, the circuits for high current are simple and generate very little heat. Let's use MOSFETS to switch up to 120 Amps for glow plugs! Source code, schematics, etc are here: https://github.com/yoshimoshi-garage/... Want one? https://www.yoshimaker.com/store
