    Scored this at work for free.

    Its for measuring exhaust temps to determine catalyst efficiency(obsolete).

    It appears to be unused, but as soon as I put a battery in it, it turned on and won't shut off.

    I was thinking about trying to replace the on/off switch.

    Now I'm thinking it may be easier just tapping into the battery circuit(wire) and adding a small external switch.

    Whaddya think?

    A donor switch finally appeared(aftermarket remote car starter take off).

    So I spliced it into the battery circuit, and mounted it to the case internally.

    Now the battery should last more then a day. :lol:
