Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.
