issue is at all rear landings,both front and rear share the same DZ brushes and i see no RDZ OR RLZ. there is rear door open relays(R1DO AND R2DO) both come in when you break the beam or hit the hall button or the DO button inside the car. i don't have the prints with me but i do not belive there is a RO relay. as far as c18 and c19 they sound like points i have been on but i do not have the prints with me. someone before me has been in this area but i have no info. coils on R1DO and R2DO have been changed, RDOL realy has been completly replaced and coils on RNT and RNP(door protction) has been changed, also all the caps. and resistor on the RNP relay(for timing) have been changed and someone added more caps. to the circuit i belive to try to get more time.? i will try to get back to the job monday and get a copy of the prints to bring home. but my friday is going to be comsumed by the great DOVER composit.
going by your latest report, double up your trailers going down to the car with a spare with a bridge. it sounds like a trailer problem particularly if its intermittant.
