14.9 volts - too high?

Alex · Mar 10, 2015

Hey folks, I've been noticing for quite a while now that my truck seems to be pretty high on the voltmeter. I've checked it with a voltmeter and the gauge on my tuner, and at idle or driving, warm or cold outside, it stays right around 14.8 -14.95V. And any time there's a sharp pull of power such as the ABS kicking in, it will spike up into the 15 range (highest I can remember is 15.5)

Any other 4th gen hemi drivers that can chip in? Tried searching but wasn't able to get much info

That voltage is nothing to worry about. When you charge a 12v battery on a battery charger it's voltage will reach a max of 15.3V while taking current. Ideally your alternator will run at 14.2v. Is your battery low on charge?

Nothing to worry about, it's normal. If it was too high the battery light would also come on.

Awesome, thanks for the responses guys. Only got about 6000km left on the bumper to bumper warranty so figured if it was a problem I'd better get on it
