Is battery being charged?

[Boat of Us]

Hi<br /><br />My o/b motor is an Evinrude 100hp. I installed a voltmeter to see the chargeing status. It doesn't have a high reading. It's about 12.5. Is it being charged? If not, where is my problem? I would guess it's the alternator. What do I do from there?<br /><br />Thanks

A tricky question. It depends on what year it is.

I recommend that you get the OMC manual for your motor. It will give you all the troubleshooting procedures + pictures & diagrams. Look here:<br /><br /> http://www.theoutboardwizard.bizhosting.com/parts_service_and_owners_manuals.html

Boat of Us,<br />Basically turn the key on and observe the voltage.Now start the motor,voltage should be a tad higher.Blip the throttle and see if the meter rises toward 13 volts or so.If it does,I would say the charging system works fine.<br /><br />Most older outboards don't have a whole lot of charge power.And they don't really put out much at idle,and need 3/4 throttle to get going.Then you're lucky to see 9 to 12 amps.<br />DHP
