9.1.1 Signal Measurement at the

Drive Controller (SEVCON)

6. Is connection between A6:X51:3 and A1:X4:3&4 okay? Is battery minus equally

connected to A1:X4:3&4?

7. Is battery minus applying at A1:X3:1 after closing of key switch and seat contact

switch? Battery minus equally at S54:1? Is connection between A1:X3:1

and S54:1 okay? Only when battery minus is applying to S54 potentiometer

switch, the closed direction contactors can control the potentiometer switch and

the S53 direction switch.

8. Connection between direction switch and drive controller okay?

S53:B2 to A6-X51:4 (forward)

S53:B4 to A6-X51:5 (reverse)

9. Connection between direction switch and A1 control unit okay?

S53:A2 to A1:X8:4

S53:A4 to A1:X8:2

10.

Are 24V applying at A1:X8:4 with “reverse” ride being selected?
