Bought this when my 1978 John Deere lawn mower starter quit working and it wa super easy to switch out. It was slightly bigger than the original opening so we had to drill a bigger hole. But overall worked great. Much cheaper than taking it into the dealership to have them change it out.

When I received the meters, I tested both and adjusted the calibration, easy to do. I installed one meter in a small power supply project, the second one hasn't been used yet but I know it works and is calibrated. Bright display, very satisfied.

Worked perfectly you replace the old school analog meter in my jump starter with a nice new digital meter. Do be careful of the plastic LCD cover, it can crack easily if you are not careful. I was not careful... It works perfectly to keep an eye on the charge level of my jump starter and acts also as a car battery tester as when I turn on the jump start leads it instead checks the charge of what those are connected to.

Amazing . It was delivered the next day I ordered . Love it.

Perfect fit
