Added a battery voltmeter

We recently had trouble with our CO/LP alarm while camping without a shore tie that turned out to be low voltage ( Emergency CO/LP Alarm Cut Off Switch ). Our a-frame did not come with a voltmeter so we had no idea what the actual voltage of the battery was until we got home (I brought some tools, but no multimeter). I had planned to install a voltmeter even more we had the alarm issue, and had ordered the meter and momentary switch (from E-bay). Total cost including shipping was less than $6. I installed it today using the wiring harness behind the paneling at the entrance of the camper.

It's hard to see in the photo, but with the momentary switch pressed it shows 13.6 volts dc. It's plenty bright enough, even in daylight.

I like yours so much better than mine. Looks like I have a new project to add on my list.
This is what I have now.
Thanks for the post

me too

Very nice install job! I like the momentary switch too. I used the other style voltmeter that plugs into a 12v outlet but have found it was inaccurate. Here's where I put my voltmeter on our Surveyor Sport 220 (I will add a switch later on)

Happy Camping !!
