Don't go too cheap on the trickle charger or you'll end up damaging your
battery. An electronic battery maintainer that stops charging, then trickle
charges again when it senses the battery voltage drops below a certain level
is well worth the $30-$35 bucks.

You answered your own question. The radio is killing the battery. This
is
a common problem on boats since they tend to sit for long periods of time
between use. Tend to run for short periods of time and be turned off and
cranked a lot. The battery is never really fully charged chances are.

If you truely want the radio to keep the stations then you have two
choices.
1. Install 2nd battery and isolator (get one from the auto parts or RV
place).
2. When you get the boat home just hook up a trickle charger to the
battery
to keep it fully charged.

The charger is cheaper. But having two batteries on the water has its
advantage as well.

Hello all,

I have a Tige 22v riders edition. Great wake boarding boat, we love it.

I have 2 questions - I hope someone can help me out w/.

1. It has a main power off switch in the engine compartment (A twist
knob). Ive noticed that if I dont turn this off at the end of the day
and
the boat sits until the next weekend the battery will be dead. I cannot
seem to figure out where the draw is coming from. Ive tuned everything
off in the boat. How can I track down the "leak".

The real pain in the ass thing is each time Im done for the weekend and
I
turn the main power knob off - I lose my radio stations each time I do
this which leads me to my next question....

2. The boat has 2 battery compartments. Id like to add a second
battery
so the radio works off a seperate battery vs the main one the rest of
the
boat uses (ie starter, lights, etc...). (I want it be transparent as
well - ie - I dont want to have to switch some switch) Is there an
idiots
guide out there somewhere that shows how to do this? I can pretty much
build anything and am mr fix it so installing something wont be an
issue -
but for some reason me and mr electricity dont get along all that
well -so
a well drawn out electrical diagram would be really really really good!!

Any help would be appreciated.

Thanks
