Review on 🏎️ Painless Performance 80111: Superior Replacement Diode Assembly for Race Car Switch Panels by Justin Ferguson

Revainrating 5 out of 5

Diode used with relay coil

Installed relay in jeep but relay had no back emf/short circuit blocking. Since the relay coil was connected to spade terminals, it was easy to install a diode (tape to +) to prevent the collapsing magnetic field from generating EMF back into the jeep's electronics.

Pros
  • Very good value
Cons
  • Negative impression
