PG 500 heading is constantly increasing by 12-20 degrees???!

Good afternoon,

We have a PG500 fluxgate compass displaying heading on our autopilot. The unit has been fitted in the same location on the bridge with no issues for 5 years. It is in a dry position.

It has now developed the following issue

On power up, Status and Auto lights are on and don't flash
The heading is correct
After 60 seconds, the heading increases by 12-20 degrees every 1-2 seconds indefinitely

I have tried going through the set up and according to the indications it's working fine.

Has anybody seen this happen before, any help would be great

Cheers

Richie

The auto light being lit is normal, but the status light should be flashing after about 4 mins of power on. If it is solid, then you have a problem. I would try clearing the compass completely and re-calibrating it. If that doesn't work; I would send it in to have it evaluated.
