Determination of malfunctions of the ignition system

The transistorized ignition system should be checked with a well-charged battery and at a temperature of 0°- -40°C. You should follow the instructions below.

The starter turns the crankshaft, but the engine does not start
Check for high voltage at spark plugs	High voltage present	Check engine ignition system
No high voltage
Check for high voltage at the distributor terminals	High voltage present	Check the rotor and distributor cap, as well as the high voltage wires. Replace damaged items
No high voltage
Check for high voltage at the distributor terminals	High voltage present	Check the rotor and distributor cap, as well as the high voltage wires. Replace damaged parts
No high voltage
Check for high voltage at ignition coil terminals	High voltage present	Replace the high voltage wire between the coil and the ignition distributor
No high voltage
Check all electrical connections of the ignition system	Too much voltage drop or temporary short circuit	Clean or replace electrical wire connectors
No damage found
Check for voltage at the +VE terminal of the ignition coil (battery voltage)	Voltage wrong	Check the ignition switch, the condition of the battery and its electrical wires
Voltage correct
Disconnect the two low voltage wires from the ignition coil. Connect a 12 V / 21 W bulb to the connector and turn on the starter	The light flashes while the starter is running	Replace ignition coil
Light bulb does not light (does not blink)
Disconnect the multi-pin connector from the ignition distributor and measure the resistance between the connector pins	Resistance is not correct	Replace ignition distributor
Resistance normal
Connect the multi-pin connector to the ignition distributor Connect the new ignition switch. Turn on starter. The light connected to the low voltage terminals of the ignition coil should flash
If the light flashes, then connect the wires to the ignition coil and check if the engine starts correctly
