Question about Raymarine RL70CRC GPS Receiver
Hi my autohelm will not keep a course when entered and set.
I.E. I ask it to steer a course say 150 and set it. it will go off and stter the boat in circles but not that course. The unit has been reset to default and the flux gate was replaced.After flux gate was replace it worked for a while then started loosing course again
Please check if the pilot is acting the right direction ,press +10 key and check if boat teers STB,
press -10 and check if boat turns PORT ,if it acts reverse, see handbook to reverse action.
Verify if compass course in standby is indicating correct course .
Do the calibration procedure as stated in in the handbook (360 degree turn)
If it still not indicate the correct course ,or is frozen, compass or printed circuit is faulty.
Check the resistance between the wires of the compass unit .(see google internet)
