I got a PH3980 sitting around the shop. It came with a truck purchased last year. I have no idea how long it was sitting behind the seat(Humidity?). I know the box is old because they all state how many miles they are good for. This one does not. I wonder if its even worth running anymore.
The code is C10743. How can I decode this number?
