Rated 5 out of 5 by from Very NiceI have used more than 50 of these without any failure. There were a few that had reversed power/ground wires but just double check your set-up when installing. Nice quality unit.

This just arrived in the mail yesterday. I hook it up to a 12 VDC battery and it displays OL ?? I double checked the polarity and it is good.  Tried a different battery, same thing Any idea what is going on here ? Pete

Asked by: hawkeye10
Usually OL will display when there is no temperature probe attached, or it is attached to the wrong terminal. I had this happen until I plugged the probe into the "CH1" terminal, right next to the power input.
