|Conservation/ Maintenance History|
Work carried out by D. Williams.
1) Control cct faulty - This fault causes the Allotter magnet to be permanently operated followed by a warm paxolin smell - I had to jack-out the relay set to stop the problem as I could not determine if it was possible to remove it from service without the diagrams - no time to fix fault. I also reinstalled the Allotter
As F/S G1 is the first choice final selector I suggest that you take it out of service every other week or month to reduce wear and to spread the load onto the other selectors. Move the link from TJ15-16 to TJ7-8 to busy it out.
