I was going through a scrap box and came across this. Can it be used with a 12 volt system & if so would it give a reasonably accurate reading? Also if it can be used how do you connect it & to what?
Actually it depends. Most hobbs today can work on like 8-36 volts....Depends on what you have.<br /><br />All it takes is power and ground to connect it. Most people just connect it to "switched" positive.
