I have a Manual and Auto setting on my livewell..it works great on Manual, but how long before it kicks on in the Auto setting? There is no knob for frequency or duration...I have put it on Auto, but its never kicked in...Im 99% catch and release so its not a huge deal..and tourney fishing I just turn it on for a few, then off...but wold be nice for it to work...1997 Javelin 400-SDC
