Am I overcharging??

I Just purchased a new gel battery and before I put it in I wanted to throw on a multi meter to see what my alternator is putting out.

I tested it and its putting out about 14.6 volts at idle. I know normally an alternator should put out 14.4 volts so is 14.6 too much or not a big deal?

This is really not a big deal, your multimeter probably has a greater degree of error than that

I agree, that difference is well within the margin of error for a digital meter, especially if it's a cheap one.

Doc here,

14.6 is not an over charge..It's well within the window for charging, However if it worries you, and you have a 3 wire alternator, you might try moving the remote sensing wire The small red wire) to the solenoid "BATT" terminal .

This will turn the regulator on later, and shut it off sooner than it would were it at the "End" of the load..

However, I suspect you may be looking at different resistance levels of the cell structure between a gel, and Liquid H2SO4 Cells..which may account for the .1 Volt verify, after running for a while, shut it off, remove a battery cable and measure..IF it reads 14.6 , it's cell structure differences. Either way it will have no effect on the battery or charging system.

The ONLY time you should worry is when it starts approaching just under 15 , 15.5 Volts..then it's over charging.
