You don't.
The same way as jump starting a car, only beware that the lorry may have 24volt electrics. Use jump leads, connecting + to + and - to -. Red to red and black to black. Use a donor lorry with the engine running, or a donor battery, using two 12v batteries connected in series if 24volt system.
Yes you can!
As far as I know you can only do it if your lorry has two 12volt batteries connected in series, ie with the positive of one battery connected to the negative of the other. If so, then you connect the car jump leads to ONE of the lorry batteries in the normal way (car positive to lorry battery positive, car negative to lorry battery negative). Try to start the lorry like this, with the car engine running at a fast idle, with all electrics on the car turned off. If this doesnt work, try again with the jump leads connected to the other lorry battery ONLY. If this doesnt work, then both lorry batteries are too flat and you'll have to jump off a 24volt lorry / charge or replace the batteries. Jumping off a 12volt car usually only works if you have one lorry battery which is ok-ish, and you use the jump leads to "help" the weak one with the car. Good luck from Norn Irn!
Yes, you could but you would damage any electronics on the truck that were on when you jump start the vehicle. I would advise against it.
Yes, as long as they're of matching voltage. You can't jump off a truck with a 24v electrical system from one with a 12v system.
Jump the circuit in the keyswitch to the "on" position, jump the starter with a starter button.
yes as long as it is a 12volt battery - i have done it many times.
You ask someone to jump your battery, or you call AAA or a tow truck company to perform the battery jump. Typically, you'll be on the road within 30 minutes after the jump.
Can you not use you key to unlock the truck?
Are you positive the battery is dead? Have you tried to jump start it? That clicking could be the starter relay.
Nope, not enough current. Tried it yesterday and failed.
cheating no
