02-06-2025I installed this on my tractor dash to monitor battery and regulator/alternator voltages. An added bonus to have USB receptacles for phone charging. Also looks like it was factory installed.

> 3 dayInstalled on motorcycle, grounded properly to frame, turned bike on and the cheap fuse blew. Once I replaced the fuse and metered the wiring, unit was inoperable.

> 3 dayThis is the third such unit that I have purchased, from different vendors, that shows the voltage as 19-20 volts when the motor home its installed in is running off the 120 volt converter at an actual 13.5V. Other than that, its fine and most convenient.

> 3 dayIt‘s not great. Does what you need, just don’t expect the connectors to hold up. They tore out after a light tug. Wouldn’t buy again.
