[Rhodes22-list] Electrical Question

[Stephen Staum]

Marc,

I have a starting battery in the lazarette that is wired directly to the 
outboard and should get charged when the engine is running.  I installed a 
second battery in the cabin that and I wired that directly to the solar 
panel I installed on the cabin top.  I suppose if I keep the battery switch 
in the both position, either charger can charge both batteries but I am 
reluctant to leave the boat w the batteries on.  I initially had a problem w 
the bilge pump killing both batteries.  I did also add a voltmeter wired 
through the master switch. It reads the selected battery and gives me an 
idea of the state of charge.  I only have lights and a 12V chiller to run so 
not a lot of battery is used normally.  The voltmeter only cost $15-20 at a 
local electronics store so it is an economical way to provide some guidance. 
Depending how your switch is wired, it may determine what is being charged.

Hello All

The Tohatsu 6hp Sailpro is equipped with an alternator. Is it as simple as
connecting the +/- leads from the engine to the +/- terminals in the
lazarette to charge the battery (ies)?  Will this charge one battery or both
batteries?  Is the battery being charged determined by the battery switch
position?

Is it posible to overcharge the batteries?

Has anyone added battery level meters to determine charge level? How do
folks know the current state of their batteries?

I know, I know - I sound like a 5 year old with all the questions . . .
