What This Product Does
The breaker contacts make and interrupt the ignition coil circuit as the distributor rotates. Their adjustment determines dwell and contributes to ignition timing; they do not perform the rotor arm's separate task of directing voltage to individual spark plugs.
Functions
- Switch the coil's electrical circuit mechanically.
- Provide the contact opening and closing action used by points-based ignition.
- Allow gap and dwell adjustment during ignition servicing.
Technical Details
- Product reference: 61660222602. Existing reference information also records BOSCH 1237013081.
- Replacement brand: OE Match; Bosch distributor applications are identified in the supplied diagrams.
Symptoms of Fault
- Difficulty starting or an irregular idle.
- Misfiring or hesitation when under load.
- Intermittent cutting out as engine speed rises.
- Burning, pitting or arcing marks on the contacts.
- Dwell or timing that does not remain stable after adjustment.
Why Replacement Matters
Mechanical wear and electrical arcing can deteriorate the contact surfaces and affect their adjustment. Renewing worn points addresses this service item, but the condenser, distributor condition and associated connections should also be inspected to identify causes of repeated wear.
FAQs
Does fitting new points complete the adjustment?
No. Check the gap, dwell and ignition timing against the correct vehicle and distributor specifications after installation.
Should the condenser be checked?
Yes. A defective condenser can contribute to rapid contact deterioration and misfiring.
Do these symptoms prove the points are faulty?
No. Inspect the contacts and test the ignition system before replacing components; other electrical faults can produce similar behaviour.
