Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
(1) Place the tester probes across pins 1-2 of the connector CN2 on the brake board and exercise
at a speed of 60 RPM. You should measure a Vdc which increases according to the exercise
level.
(2) As for step (1) but across the two fast-on at the input of the brake.
(3) As for step (1) but with everything reconnected, and across the brake winding.
If you replace Display board/Brake board, check that its SW version is updated, otherwise
install the last version.
