    Is there a cheap and simple way to monitor my battery in the boat to see
    how much juice is left. I just moved the battery to the front of the boat just
    wondering if there is a gauge i can mount or some device i can use to check it. Thanks

    (cheaper the better the girlfriend won't let me spend to much more:wink:)

    And Remember to put the gauge on a switch so it is not drawing power all the time.

    My sonar unit shows battery voltage so I have an idea of it's health. You need a voltmeter either at the console or installed inline at the battery so you can check voltage when you check battery water. Tight lines.

    Maybe a momentary on push button would be a good idea. That way you can't accidentally leave the switch on. Just push the button when you need to check the battery voltage.

    My rv has push buttons inside - I'm sure they have them made that way for boats. I need to get a duel one beings I run my livewell on it's own bat. I figure I can do away with my speedometer - it doesn't work to well anyways - cheep plastic fin always moves up. Besides I know how fast I'm going in the pontoon - NOT NEAR FAST ENOUGH!!!!:smile2: For now I just use one of the cheep walmart bat checkers - alligator clips - at least then I have some idea.

    The easiest way is to simply lick the battery. Wait, we are talking about a 9 volt right? If not, licking could still work. You will just need a really long tongue like gene simmons.

    o'reilly's sells a pretty nice little volt meter (battery gauge) that lights up also. it is only like 12 or 13 bucks. we hooked it up to a switch and it works great.
