Review on Waterproof Digital Car Voltmeter: 2 Pack LED Display Panel for Vehicle Truck Motorcycle Boat Marine ATV UTVeter by Raffy Baer

The truck has no oil or tension sensors. The truck was fine until one morning it wouldn't start. I thought I had a serious problem as the battery is only a year old. It turned out to be the battery! I didn't want to check the baht already. daily with a meter, need something to tell me if it's been charged. two wires and this sensor provides the information I need. Also indicates that the generator is running. A switch has been installed so you can turn it off when not needed. Next I want to install an oil level sensor. Debate between digital and mechanical.
