| N-W. --- Y7680 All/H.22.9.30. X5680 X7680. Technical - Seizure of Lever of Battery Ignition Contact Breaker on its Pivot. Thank you for youe EFC1/AD.15.9.30. We have had several cases of sticking rocker arms. In each case the car has been brought to us with a failure of the battery ignition, and this has proved to be the cause. It seems to arise from the bush being fitted with very little clearance in the first place. A contributory cause is that drivers never clean or lubricate this part. A.S. | ||
