    Default New with a few questions

    Hello all,
    I recently purchased two c7500 topkicks, one is a 99, the other a 2000 model. They are both bucket trucks, and we use the 2000 nearly everyday. The reverse lights stay on all the time. That's problem number one. Second problem is the high idle switch doesn't work, it lights up, getting power to switch, but it will not idle up. They are both gas engines, and both came in from northern ill so there is some rust. I tried a search and didn't find anything. Thanks for your help and time.

    For reverse lights try the connections and see if rust from salt is causing the issue. Also check your back up alarm cause if the lights are staying on so should the back up alarm. I would track the wiring from back to front and look for any corrosion any where. Feel the wire as the corrosion can be hidden within the casings and not visible. We had several problems with power cord failures and found hidden corrosion. Have your mechanic test the wire till he finds a break
