X.4652 X.7690. X.8783. PHANTOM IGNITION. The question of the life of contact points has received constant attention. These investigations have been going on since the first Phantom cars were proposed. We have run tests of 1000 hrs. on the rig but we cannot reproduce the failures which occur on the car. We are also preparing a standardisation sheet for a new coil which will take less current. This again is with the object of improving the life of the contacts. On the next car going to France we are testing an alteration in the ballast resistance with the object of improving the life of contacts. We can assure you that this matter is receiving the urgent attention of the Experimental Department. We should be pleased for any helful suggestions to reduce this fault.
