Draining battery

[crookedmullet]

I've got a 1996 60hp Mariner. At the beginning of the day, my battery was reading fully charged, had no problem starting engine. As the day went on, I noticed the meter and the battery was slowly draining. Within a couple of hours the the engine just quit. From my understanding, the stator and voltage regulator are the things to look at in this situation. Is there any tests I can do to eliminate either/or, and is it recommended to replace both?

Re: Draining battery

The first thing I would be looking at is the regulator/rectifier as the culprit. Generally, if your system isn't charging, that's what it is. This is not to say that is it definetly, but just a good guess. At over 100.00, it's not a cheap fix, but nessesary.<br /><br /> Rectifier <br /><br />Some electrical reading numbers;<br /><br /> web page <br /><br />This may help, too:<br /><br /> web page

Voltmeter should read a bit over 12 volts with ign on and go to between 14.1 and 14.7 running.<br />Any less and it's not charging enough and you need to do what rick has said.

Re: Draining battery

I just replaced both the stator and voltage regulator and all seems to be working well. The voltage is climbing on the meter and it's time to go fishing!!<br />Thanks for all the help!
