    Default Truck wants to start on its own.

    Here's a new one. I shut my truck off in the drive through to order. When I went to start it up it did, no problem, but I heard a whine like the starter didn't disengage. I turned the truck off and tried to restart and, nothing. Got home, disconnected the batteries replaced the starter, went to reconnect the batteries and the truck tries to crank the instant the cables touch the battery. I've also replaced the ignition switch thinking that might be it. No luck. Any ideas would be greatly appreciated.

    Did you replace the switch, or just the lock barrel? Check that the start wire to the starter is not touching the live wire.

    So after hoping it was the starter and preying it wasn't the wiring somewhere I couldn't access (which is 90% of the wire it seems), it turned out there is a tab on the battery cable to the starter that WAS shorting against the ignition post. I was pretty certain I checked that but I was wrong. Thanks Grant.
