Voltmeter to bike

Another DIY project of mine, how to add a voltmeter to the bike. Original posted on my blog.

I have few things on my V-Strom 650. And because I want to do long trips, itís good to keep an eye on the battery from time to time. As such, I decided to add a voltmeter. Here is how I did it.

Iíve purchased a voltmeter for about $5 from eBay. Just make sure itís waterproof. I chose the color of the LED to be yellow, just to match the yellow dash. I decided to cut off the small ears from the sides. This is what I was left with.



After adding some more extension cables as seen in image above, Iíve threaded the cable through the dashboard and the plastic thatís holding it. Looks like this



To have the voltmeter start when the bike starts, I decided to mount it to the horn. This way, it only gets power then the I power up the bike and itís only 0.5v off.



I have added the negative pole to a screw I found on the handlebar. Could have been any screw for that matter. It works.



And this is the final result. I used some double sided tape to fix it to the bike. How well it holds ? Well, since Iíve mounted the voltmeter, Iíve been through rain and 40+ degrees temperatures. The bike stood in rain for days and stood in bittering sun for hours. Iíve been through some rough roads and 8+ hours of continuous rides. Never had a problem, never moved, never fell since the first mount. What tape did I use ? I think itís an ordinary double sided tape, very very thin in width and unbranded.



Total costs: $6

That probably won't cause any problems because the current is low, but grounding there can be a problem. Current will be running through the aluminum bar clamp, the steel handlebar, the aluminum triple clamp, the steering stem, the steel bearing inner race, the steel ball bearings, the the steel bearing outer race, the aluminum frame and to the grounded engine. That doesn't include the steel screws connected to aluminum castings. When current passes through the junction of dissimilar metals, especially if that junction is wet, it can cause chemical corrosion of the more active metal, the aluminum in this case. It's best to ground accessories to the negative battery terminal or to a black wire with a white stripe, the ground wire system on V-Stroms.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Somehow, I prefer the comfort and accuracy of looking at real numbers rather than leds.
Having any indication is mo bettah than wondering.

I ran both leads from my datel voltmeter to the Eastern Beaver PC-8 fuse box.
Running current through steel and aluminum will cause the aluminum to be a sacrificial anode, quite unwise actually..

Sacrificial anodes are used in marine applications to protect valuable propellers from the corrosive effects of saltwater

I have to give a shout out to Clearwater.

Clearwater Voltage Sentry Review - webBikeWorld

https://www.clearwaterlights.com/infopg_cvs.html

Accuracy
Without strapping a high quality Volt meter onto the triple clamp and monitoring voltages around town, the CVS allows instantaneous monitoring of your battery/alternator system. This system is the most accurate voltage monitoring device of its kind anywhere. Accuracy is better than 1/4 of a percent!


I don't need a number.... "Green is good".

Rock solid!

I made mention of that same thing on his Facebook post, but not nearly as thorough as you did.

Had one and I "hated it", show me numbers......I want to see numbers. When hooking up my DVM, I found that stupid LED to not be very accurate at all.......those are my observations.

Is green 12 volts or 14.4 volts?

Your $5.99 DVM?

I'll roll with something tested and proven accurate.... I have faith the Clearwater products. Lots of my friends have years of experience without issue.

I will have you know that my cheap Chinese made waterproof LED voltmeter is practically dead accurate, and this has been verified with a "several hundred dollar" annually calibrated biomedical department Fluke DVM. Just like Notacop said........"Is green 12 volts or 14.4 volts?" I can assure you that a charging system is on it's way out, and that stupid LED is still going to be green. Just sayin......
