Gaffrig Compass
 

My gaffrig compass is not working properly. When I first got the boat I noticed the compass was not that accurate and would just spin for no reason sometimes. I didnt ever use it so thought nothing of it. Now it does nothing, every once in awhile it will spin but usually sits at 225 degrees. Its got voltage and I've tried setting up the compensation as described on the Livorsi website. I have a GPS but I want to try to get the compass working too. Any ideas?
