I have a 225 oceanrunner .What amps will the moter be putting in to the batterys.I always seem to be having a flat house battery.The cables from the engine are straight on the moter instead of going through a switch.Which I know is wrong.There is a unit which is connected to the house battery via a wire from the engine.I guess thats what charges it.The two batterys can be paralleled via a switch which is good.And the house battery can be isolated as well.But not the start battery.Shall I keep the little charging unit.Or buy a vsr and change the whole setup??? Thanks

Re: battery wiring

Fluffy -<br /><br />The first thing to make sure of is that you have 2 good batteries. With everything off set the battery switch to off so that the batteries are not connected. (Or remove the battery cables alltogether.) Next charge the batteries one at a time using a conventional battery charger. (I recommend a smart charger). Then let the batteries sit for a week and then give them a try. If they go flat in one week then the battery is likely the problem.<br /><br />If you can get a hold of a voltmeter you can make sure that the battery is getting a charge. Set the meter on volts and measure the battery voltage. Before starting the motor it should read around 12.6 volts. When you start the motor it will drop and then come back. Rev the engine a little and it should go above 12.6 volts. Take the boat for a ride at WOT and it should be above 13 volts. Anything above 13 volts should charge the battery.<br /><br />If the 225 oceanrunner is a typical outboard, you shouldn't expect alot of amps out of it. Also, it takes volts plus time to charge a battery so you may want to use a smart charger when you can.<br /><br />Good luck.
