Alarm Serial Line Problems

147 JTDM 2005

Anyone had a problem with the alarm randomly going off for short periods from a second to maybe 30 seconds ?. Diagnostics from the status light show 8 flashes which is Serial line problems, lack of or poor signal.

I'm pretty sure it started after a heavy downpour. Checked the drain in the scuttle which was partially blocked so thinking water may have backed up and got into something but not sure what. Anyone had similar problems and managed to cure it ? Cheers.
