i have a 1992 29' sundancer and there is a random alarm that goes off. It is not the loud temp or oudrive fluid level alarm. It went off in the middle of the night while we were plugged in to shore and sleeping for 30 seconds. It did this occasionally every hour then stated going off randomly, it is under the dash, ran the boat, no problems, going on off, not a really loud noice but bothersome, any ideas??
