I have one of these installed on my Versys to help keep an eye on the charging system. It is a simple 3 color LED with a mini circuit board in the back. There are only two wires to hook up - Black to Frame/Ground and Red to switched +12V.

I really like the simplicity of Sparkbrights voltmeters as they can be inconspicuous in the mounting. A simple LED to glance at once in a while. I don't care for the array of LED style meters or the digital display as they flicker and change every .1 volts.

I ordered the 5mm Eclipse (auto dims as it gets dark out - very cool).

The LED displays the following as standard:
>15.20 Volts Green/Red Alternating (overvoltage)
>13.20 Volts Green (Charging)
>12.45 Volts Amber (75%)
>12.25 Volts Red Slow Flashing (50% to 75%)
>12.00 Volts Red 2 flashes repeating (25% to 50%)
>11.80 Volts Red 3 flashes repeating (25% to 50%)
>0 Volts Red 4flashes repeating

Basically, underway after engine has been started and a little bit of throttle it will stay green indicating that the bike is charging. Sometimes at idle, the voltage will drop down to Amber because there are not enough RPM's to keep the voltage above 13.20 Volts.

You can order from Andrews Website or from his Ebay store. I have no affiliation with Sparkbright but have ordered 2 of his voltmeters for my bikes and 22 of them for monitoring 12V batteries where I work. All of them are working properly and verified with good quality voltmeters.

Andrew can program custom voltages if you don't care for the standard programs listed above, just send him an email.


voltmeter, battery monitor items in Sparkbright Products store on eBay!

Here are a few pix of my install.

Nice, and a very neat installation. Can I assume you wired it to Earth and the headlight or was it to somewhere else?

While seated in front of the bike with the headlight assembly completely unplugged and set aside, there are another 2 connectors to the left under the big black plastic cover. These go up to the right hand controls of the handlebar. Slide the cover up and there is a 9 pin connector (not all populated). I probed the connector and found a wire that appeared to be black with dark green or gray dots that was a switched +12V. If you unplug the connector, there is a green dot painted on the outside of the white connector. That was the wire I soldered onto. It was a corner socket.

I didn't cut or splice into the wire, I did not want to disturb the flexibility of the wire so I did a little trick that I have done many times in wiring and has never failed me. I used a dental pick to use as an extraction tool and I pressed the locking tab down so I could eject the socket.

I soldered the red wire to the strain relief portion of the ejected pin. I cleaned off the flux with alcohol on q-tips and reinserted the socket back into the connector. Now the red wire comes out beside the OEM Switched +12V.

I did not try to splice into the headlight wiring because when I remove the headlight assembly and set aside, the voltmeter is still attached completely to the bike. I did not want extra wires to unplug.

I connected the black wire to a ring terminal and attached it under the horn attachment bolt (frame).

I just made a 20 mile test ride and everything works as it should. There is almost zero current being used by the voltmeter so there is not a load being created.

Thanks for the wiring tip, good to know. I have also, in the past, removed about half an inch / 1 cm of insulation, pushed the wire thru and relied on the plug/socket holding it all together - but yours is a more professional and sensible way!
