Testing Breakerless Transistorized Ignition (TSZ)
Testing breakerless transistorized ignition (TSZ)Preceding work:
Testing, adjusting engine. Refer to Engine Testing, Adjustment. Testing and Inspection
Precondition for test
Spark plugs, ignition cables, distributor rotor and distributor cap in proper mechanical and electrical condition.
Test e.g. by visual inspection, measuring resistance and ignition oscilloscope.
Note: Pay attention to the safety precautions when performing work on the ignition system. Switch off ignition when unplugging and connecting the contacters at the TSZ control module.

Note:
- If the specified value of a test step, e.g. test step 1 .0, is in order, continue immediately with test step 2.0.
- If the specified value of step 1.0 is not in order, it is then necessary to continue with step 1.1.
