Thanks guys,I understand the steps of positive to positive and ground to an unpainted metal ground or on the engine or body that does not move when the engine is cranked.
The part that threw me off was 'if recharging with the battery installed on the vehicle, be sure to discounnect the ground cable'.
I think the confusion was on my part, I think the manual is talking about recharging with a charging machine/equipment with battery installed on the vehicle,while I was looking for jump start information.
I think the ground cable does not have to be discounted when boosting from another vehicle with a good battery,my 2 cent? Should it?
