My 2001 18 Dauntless with a 135 Optimax has been exhibiting some peculiar electrical problems since the end of last season and now at spring startup has me wondering.The last time I used the boat back in November I was coming across the lake near wide open in moderate chop when the auto bilge lamp lit while under way. All seemed normal except that it stayed on for about 15 minutes all the way to the ramp. I listened to what I thought was the bilge pump dieing while putting the boat on the trailer and verifying that the bilge switch was in the off position.
I disconnected the battery and ended up winterizing the boat figuring I would deal with a new pump this season.
I made the mistake of just cutting the power leads without checking the pump while it was in the boat and just for kicks wanted to hear what a sick bilge pump sounded like so I connected it to a battery I leave on the boat for the winter. Much to my suprise it sounded normal. Reinstalled it verified that indeed it worked and thought that was the end of that.
Went out to dinner believing my spring startup had gone smooth and all was well. Wrong, as I was covering the boat after dinner I noticed the gauges were lit as though the motor would be running except there was no key in the ignition and it was indeed in the off position.
Any thoughts on where I should start? Thanks,Tony
One strange note I made while I had the pump cut out of the circuit was that there was no power at the leads from the boat side while the bilge switch was in the off position. I have noticed that in the past the bilge would go into the auto mode when there was enough water in the bilge signaling the pump to do its job.
Is this normal - should'nt there be power no matter what in the event the bilge float system detects water and activates itself?
Also now that I think of it the old battery I leave in the boat over the winter to lift the motor if need be had adequate power in it to lift and drop the motor when I picked up the boat for the spring start up routine of mine although it was in its usual weak condition.
Just seems odd the battery was not zapped of its power from a trickle drain after sitting for 4 -5 months.
Is there a way to measure if there is a small load on the battery with the boat and all switches in the off position?
