Anyone install a small volt-meter that displays voltage in real time? (Like 11.0 - 15.2 volt range I guess.) I've seen a couple real ugly ones with classic red or green LED segments, but none with a nice back-lit scheme.

Sparkbright

This is not what you are asking for specifically but I have installed them in my last 4 bikes. He used to sell on Ebay, but now sells only direct. He is from the UK and I have purchased from him 5 times. He has been an honest seller and they have never let me down. You could have charging problems well before you "break down" and these meters make it easy.

The thing I like about his simple design is that green is "good to go". Install by tapping into an ignition switched 12V. He states the current draw is low enough to hook direct to battery, but I personally do not want any unnecessary draw when parked.

Let me explain why I like this voltmeter better than an actual digital readout. Voltages are constantly fluctuating while you ride. With a voltage display in real time, the number(s) past the decimal are constantly changing. To me, that is a distraction.

Once installed, when I turn on the ignition (before start) it shows amber (normal). After firing up the bike, it turns green. That's it! I have verified these are very accurate with a variable voltage power supply and his chart is spot on with the voltages he sets them to.

Since seeing this post, I just ordered an 8mm Eclipse for my R3!

Ride safe,

That's pretty cool, didn't know such a product existed. But yeah I'm looking for digital read-out, to see pre and post ride voltage, and what's happening precisely during charging when the bike is running. In interest of my lithium battery pack, specifically over-voltage which I don't think the Spark Bright would catch.

Yes it will flash green/red for over voltage...

>15.20v ■■ Green / Red alternating over-charging – regulator problem not applicable
>13.20v ■ Green steady normal charging exceptional battery charge (uncommon)
>12.45v ■ Amber steady under-charging – alternator problem normal battery, charged and in good health
>12.25v ■■ Red slow flashing not charging – battery low fair battery charge
>12.05v •• Red 2 flashes, repeating not charging – battery low low battery charge
>11.80v ••• Red 3 flashes, repeating not charging – battery very low very low battery charge
<11.80v •••• Red 4 flashes, repeating not charging – battery very low consider renewing battery

I understand this is not what you are looking for, just listing the specs.

Ride Safe!
