The ELEKTRONIK SACHSE digital ignition kit ZDG3 replaces original electronic ignition units as well as old points including the weights advancer or manual advance wires.
The Elektronik Sachse ZDG 3.23 (ZDG3) digital ignition kit replaces original electronic ignition units and old points, including weights advancer or manual advance wires. The manual explains the ignition's RPM ranges, the wasted spark principle, and the coil requirements.
It covers the scope of delivery, mounting of the pickup plate, magnet disk and sleeve hub, electrical connections with terminal assignments, and initial setup using the LED indicators. The electrical section also includes notes on crimping ferrules and spark plug caps.
