can leaving ignition on flatten my batteries?

Folks,
Today at our club flying site I left the ignition on for 5 hours by accident.

When i returned to the truck it was as dead as a dead thing. Just a glow from the lights on the dash and a click from the solonoid.

Do the glowplugs keep coming on waiting for me to turn the key or is there some other big current drain you know about??


I got it started with the help of fellow club members but it seems very odd that this would happen just by leaving the ign switched on!!!!!!1 Noi lights/no heated screen had been left on, in fact nothing!

Any ideas please

Yep , just the ign on will flatten the batts as relays are switched in and the fuel shut off will be held open and the ECU's energised .

Great, Thanx for that. At least i now know that there is nothing wrong with my vehicle.
