[DG] [Dg11] Drive stopped issue

[Derek - Raymarine - Moderator]

Hi vmi2uscg

Thankyou for your enquiry,

The clutch operation sounds correct, when AUTO is selected the wheel should feel locked, the most common cause after the clutch failure is the motor brushes, they could either be worn or sticking in the brush holders.

This can be checked by temporarily dabbing the motor wires onto the main power into the course computer/ACU and check the operation of the drive - if the motor is noticeably more powerful and brisk in terms of operation, then the cause can only be a high resistance connection in the cables between the ACU and the drive or the ACU itself.

Note that for small course changes the ACU will not output a full 12v anyway, if you select 4 x +10, then you should expect to see closer to 12v when the drive is connected, also note that with no drive connected the ACU will detect that and reduce the output voltage too.

Finally check through calibration to make sure the correct drive is selected, try resetting the pilot to revert to factory settings in case ther eis an isse there too.

Derek
