On a previous 914 I had many years ago I experienced a "no crank" condition that I traced back to my ignition switch. It seems that in the start circuit on the switch, when the key is released a tiny "backfeed" of current from the starter solenoid arcs across the terminals on the ignition switch, and over time damages the contacts.
After a little research I determined there are two ways to stop this "current backfeed", one is to install a diode to ground in the starter wire, another (which I did) was to install a simple 5 pin relay.
