need a little help. when i place my i-pilot on anchor - it only holds for about 5 seconds - then shuts off. i noticed when i click the anchor once it flashes 3 or 4 times - then when i click it again - the anchor light stays on solid. however, either way - it only holds for a few seconds - then shuts off - and i go sailing.

any ideas on what i may be doing wrong? thanks in advance.
