System Check With Spark
- If spark occurred in System Spark Check, turn control unit around grounded bolt until fuse is visible from side. Pull back rubber cover from fuse, but do not remove fuse.
- Connect voltmeter positive lead to terminal 4 and negative lead to terminal 2. Turn ignition switch "ON". Battery voltage should be read. If not, check wiring back to battery.
- If battery voltage was present, check ignition coil primary and secondary resistance in same manner as for Audi and Volkswagen models.
- Primary resistance should be 0.52 - 0.76 ohms. Secondary resistance should be 7, 000-9, 000 ohms. If not to specification, replace ignition coil.
- If coil resistance is satisfactory, remove coil wire from distributor. Connect voltmeter positive lead to terminal 15 and negative lead to terminal 1 of ignition coil.
- Turn ignition switch "ON". The voltmeter should drop from 6 volts to zero (0) volts within 1-2 seconds. If not, replace control unit. If so, engine should start.
