Troubleshooting
Engine misfires or runs rough
Check that the rotor arm is correctly seated on the distributor shaft and that the distributor cap is properly aligned and secured. Inspect the distributor cap and spark plug wires for damage or wear.
No spark at spark plugs
Verify that the rotor arm is making proper contact with the center electrode of the distributor cap. Ensure the ignition coil and other ignition system components are functioning correctly.
Rotor arm appears loose or wobbly
Ensure the rotor arm is fully seated and the securing mechanism (if any) is engaged. If the shaft it mounts on is damaged, the distributor may need further service.

Setup, Compatibility & Care
Compatibility Verification: Before installation, confirm that your vehicle's make, model, and year precisely match the specifications listed. This rotor arm is compatible with General Motors part numbers 90230573, 90376979, 90442356, 90540398 and Opel part numbers 1212204, 1212206, 1212207, 1212224. It is specifically designed for the Opel Ascona C (J82) 1.8 and 2.0 i models produced between 09/1987 and 08/1988.
Installation: Installation typically involves removing the distributor cap, carefully lifting out the old rotor arm, and replacing it with the new CI Ignition XR148. Ensure it is seated correctly and securely. Reattach the distributor cap. It is recommended to consult a service manual or a professional mechanic if you are unfamiliar with ignition system components.
Care: The rotor arm itself is a non-wearable part under normal conditions. However, it is crucial to keep the distributor cap and rotor area clean and free from moisture, oil, and debris. Regularly inspect the distributor cap for cracks or carbon tracking, as damage to the cap can affect rotor arm performance.
