Bosch 901-602-961-01 Ignition Condenser for Points Distributor Systems

The Bosch 901-602-961-01 is a precision-engineered ignition condenser designed for classic points-type distributor systems. This critical ignition component works in conjunction with the contact breaker points to ensure reliable engine performance and extend the life of your distributor.

Key Functions:

• Prevents electrical arcing at the contact breaker points when they open
• Minimizes burning and pitting of the points, extending their service life
• Absorbs voltage spikes generated in the primary coil circuit
• Aids in rapid magnetic field collapse for stronger secondary spark
• Delivers crisper spark at the plugs for improved ignition performance

Technical Overview:

In a points-type ignition system, when the contact breaker points open, the collapsing magnetic field in the ignition coil can generate voltage spikes up to 250 volts in the primary circuit. Without a properly functioning condenser, this energy would arc across the points, causing rapid erosion and premature failure. The condenser absorbs this energy and releases it in a controlled manner, protecting the points while enhancing ignition efficiency.

Application:

This Bosch condenser is designed for use with Bosch 009 and 031 distributors commonly found in classic European vehicles. Note that minor modification of the condenser mounting plug may be necessary to fit certain distributor body configurations.

Regular replacement of the condenser during tune-ups helps maintain optimal ignition system performance and prevents unexpected breakdowns caused by ignition failure.
