    Default Leaving ignition on the 'ON' position... Hurt the truck??

    i've always heard that leaving a car in the 'ON' position is bad for it... burn out coils...

    but i've always heard this from people w/ old cars.. and old ignition systems...

    In the old, pre-electronic ignition days, you could burn out the points in the distributor. But since A) Tundras don't have distributors and B) don't have points, it isn't likely to happen to you.

    I accidently left mine in the "On" position last week when I meant to leave it in "Accessories". I discovered this after about 4 hours. Except that the battery ran down, I suffered no ill effects.

    What do you mean by leaving it in the "ON" position? While parked, or listening to the radio w/ the truck off?

    When I am getting out and am going to be back in it driving away within about 3 minutes or under I always leave the truck running as to not wear the starter.. probably 5-10% of the hours on my engine are idle. I sit in it alot, soccer games, picking up friends, waiting at the grocery store while my gf runs in, loading/unloading tools for jobs.

    Probably the longest ive left it running at idle giving it no more gas is about an hour. But I will periodically rev the engine to about 2krpm and hold for about 30 seconds.

    I have wondered this too, the longest i have left mine on is about 2 hours, while i was detailing it. I havent noticed any ill effects, but now it seems like it is ok to do, just dont drain the battery all the way down! I leave it in "ON" with the doors open so i dont hear that damned warning beep while im working on the truck listening to the radio
