Training Titbits .. Jumpstarting

[Gordon Brown]

Indeed - the instruction to switch-off to disconnect the leads goes against the training I've had previously, not to mention the instruction for undertaking a jump-start in my vehicle's handbook.

I'd be interested to hear the rationale / provenance of that particular approach.

[James Addy]

I agree, in that the way I was taught was to start engine and leave running whilst carefully removing the leads.

And my guess is that any 'official' training, may say turn off engines before disconnecting to try and safeguard any shorting or Engine Management Unit issues (But can't see how it would avoid any of that if the engines were off - your dealing with potentially raw electricity, so be careful, be safe, and keep the leads apart at both ends at all times until nowhere near vehicles and/or batteries)
