Single LED voltmeter

[Obo]

Here may be the easiest way to make a tri color single LED idiot light. (assuming you can swap the tri color LED for the 3 led's listed here)
You may also need to increase the 1kohm potentiometer.

I have an Eclipse 8 in the dash of my ST1100. Works fine, like the auto dimming and can see it in the sunlight. I mounted it opposite the trip reset button, looks like it came stock!

I have been reluctant to cut a hole to mount a voltage gauge. I recently came across this https://www.aliexpress.com/item/32788267780.html ... ADD TO CART

I have mounted a 7" tablet to the bike so this works perfect. Install the app and watch the voltage on the screen. Hopefully I will be able to overlay the voltage over google maps. Have to wait for it to arrive to be sure. It does data logging for diagnostics as well. May come in handy when my battery starts going south.

Like the ideal. App seems to have some issues reading user comments.

Hopefully this works well for you. I understand not wanting to drill or cut holes for farkles. While I drilled a hole in the ST's right hand speaker grill to mount a single LED monitor on subsequent bikes NC700X and Goldwing I found a location down in the fairing to mount the LED where the light is visible from a glance and is shaded from direct sunlight.
