What's your volt meter reading when cruising around town? Options

[raynekat]

Just curious what the typical volt meter reading is:

1) when you're sitting at the stoplight

2) cruising down the boulevard at 3-4000 rpm

Trying to see if I'm seeing typical or low readings
Thanks

I just recently noted a low charging issue that I believe came down to an alternator/voltage regulator mismatch.
I was using a Bosch VR with my Motorola alternator.
Now I've switched to a Marchal VR and the charging voltages look better.
About 13.75 volts while cruising.

Superhawk....again some great comments and insights.

The Antigravity Rs-30 has 1200 cranking amps and weighs 11.5 lbs (one of important reasons I chose this battery....possibly the wrong one).

The Optima 34R has less at 800 cranking amps and weighs in a whopping 37.9 lbs. Obviously this is necessary (the added weight) to get the higher amp-hr rating.

Actually, after the current (or voltage) drops low enough in the Antigravity battery, it turns itself off saving enough power to do 2-3 restarts. Supposedly you'll never get stranded. ??? When I was driving around at night with all the lighting on and the wipers going, my little LED gauge plugged into the cigarette outlet was dropping down to 10V. That got my attention as well as the lights dimming quite a bit while idling at the stoplight.

Sounds to me, a larger amp-hr battery may be in my future.
You are likely right that this would be a great battery for a race car.
It's very lightweight and starts the car.

Wonder if this Antigravity will fit in my Vespa??? (IMG:style_emoticons/default/idea.gif)
