I have just lost 4 lanes and have no idea how to fix them!!!
It all started 2 days ago, i had a chassis start playing up, it was doing the same fault i always have with theses chassis, odd lane sweep overun and table not coming back down on respot. i wasnt in myself but one of the other techs swapped the chassis over for the spare which had just come back from AMF, but as soon as he switched on the power to the logic it blew the fuse, so he changed the fuse and tried again,this time it went bang!! it blew the fuse holder apart and wrecked the in line surge protector i have fitted between the power supply and the chassis, and it tripped out all the other chassis.
So i refitted the old chassis as at least that still ran the even lane and sent the burnt chassis back to AMF. this ran fine for the night but then i got a phone call in the morning to say that this lane would not cycle at all. This is where it gets fun!
the odd lane (lane 1) wouldnt run anyway but now the even lane would not cycle when the ball trigger was activated, it would cycle from the chassis though, it would not cycle from the front end box but if you press sweep reverse on the FEB it cycles???
So i assumed that the chassis going bang must have caused a problem in the FEB, i dont have a spare and wanted to make sure that it was the FEB before sending it off for repair, so i swapped it for lanes 3&4, the FEB from 1&2 worked fine on 3&4. so i assumed the fault must be either in the chassis or somewhere inbetween, so i fitted the chassis from 3&4 onto 1&2 it had the same fault, so i put it back onto 3&4, the problem is it carried the fault back with it!! now lanes 3&4 have the same problem, now if you press table on either 3 or 4 FEB it cycles lane 3, and if you press sweep reverse on either lane it cycles lane 4.
