Technical characteristics of the ignition system (Opel Kadett E)

The engine ignition system is battery-powered, contact, with a nominal voltage of 12 V. It consists of an ignition distributor, ignition coil, spark plugs and high-voltage wires. The ignition distributor is driven by a bevel gear from the camshaft.

The marks for setting the ignition timing are located on the crankshaft pulley and on the camshaft drive cover.
