Latest News Ignition – Condensers, Contact Sets, Distributor Caps and Rotors What a Technician needs to know when diagnosing faults for condensers and contact points on early points distributor systems and distributor caps and rotors on all points and electronic distributor systems. We all know that the points distributor system numbers have been reducing over the past years, but it is still important to ensure that they are diagnosed, tested and repaired correctly when a vehicle with this system visits your workshop. Important features of the points type system.
Lubricating the CAM and rubbing block will ensure that the contact point gap will not reduce quickly due to wear of the rubbing block during operation. The reduced gap can create a hard start condition and excessive dwell that can cause damage to the ignition coil. Important features for Distributor caps and rotors. All distributors whether contact type or electronic, require an internal rotor and a distributor cap to ensure the high voltage / HT spark created by the ignition coil be distributed to the correct cylinder without the spark tracking to ground or any unwanted area. The voltages on later electronic distributors are generally extremely high and many utilise male spark towers to reduce any unwanted tracking of the spark during peak voltage - High load / hard acceleration. Achieving full HT spark to the spark plugs will generally reduce the chance of engine misfiring. It is important that the condition of both distributor caps and rotors are closely checked for any tracking signs prior to replacing any other ignition component.
Note: Di-Electric grease/paste is generally used on the distributor cap tower to form a seal for the HT leads to prevent moisture creating a spark track that can cause engine misfiring. This paste also allows for easier removal of the HT leads later without HT lead damage.
