RPM Isolator Package
The RPM Isolator Packet contains the essential components required to condition the RPM signal from your Magneto for accurate readings on Electronics International instruments. These isolators are designed to attenuate strong signals that can otherwise cause high or jumpy RPM readings. The kit includes primary ring terminal isolators for the mag switch, along with additional inline isolators to fine-tune the signal strength for various magneto types. This packet is compatible with the R-1, CGR-30P, CGR-30C, MVP-50P, and any system utilizing the EDC-33P.
