To eliminate this issue and restore gauge function we are happy to offer Ivo Christov’s batteryless SI board. Developed by Bart Smeets in cooperation with Ivo Christov, this multi-layer printed circuit replaces the failure prone, battery laden service interval board and restores proper gauge functionality.
