✅ Best BULLETPROOF Battery Load Tester Switch Repair - Keep burning up the switch? Add a 120A Relay!

This video covers the repair of a battery/alternator tester where I not only replace the bad switch, but I also add a 120 amp relay to handle the heavy current load. There is no way these tester will last for long because they are putting a "100 amp" load on the battery which is handled by a switch rated at 16 amps. This repair turns a device that's set up for failure into something that should last a lifetime. The load tester in this video is almost 6 years old and while I could have replaced it with the harbor freight unit for about the cost of the parts I used to fix it, this fix makes the unit 1000 times better!
