Re: battery question
while we are talking about charging a vehicle and boosting etc I wanted to mention that when we boost a vehicle using a vehicle with electronic fuel injection we should first connect the boost vehicle and allow it to run for a bit to charge the dead battery some but then we should shut the boost vehicle off for the time it takes to try and start the vehicle with the dead battery. this is because when the boosted vehicle starts it's alternator may produce a spike in voltage that the booster vehicle voltage regulator needs to work very fast in order to control the voltage it is also putting out. if that takes a second then the voltage that is produced and uncontrolled for a second may fry some sensitive electronics in the boost vehicle.
