October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Quick Check
Connect a voltmeter or a test lamp between ignition coil terminal 15 and ground. Start engine. Observe voltmeter or test lamp.
If voltmeter needle pulsates or test lamp flickers, the Hall sender and control unit are probably OK.
