Re: Jumper cables and possible surge issues to electronics with new vehicles

Have you ever looked at how noisey the rectified output directly from an alternator is?
Can't say I have. The issue he spoke of was 'surges', not noise. I do know from reading computer forums that two hard track down problem areas are power supplies and processors that have either overheated or were over taxed. Down the road, weird things start happening (most would blame viruses or corrupted programs or the O/S itself) even though the computer is actually working.

Over the past several years though they have seemed to get more commercial with less focus on his technical experience.
I have noticed this also, especially with This Old House that I have watched almost from it's beginning. One thing both programs don't always do is name the actual product, just a description and/or showing the item. Many times you can't really see the name of the product unless you can recognize the item from either using it yourself or from seeing it in a store.

The problem of using one of those portable power solutions is keeping it charged. For myself, this is the first time in I can't remember how many years I had to 'jump' one of our vehicles (three total). The time before that was equally as long (5 years each?). So it would make no sense for me to go that route.

Would it be of help to not have the 'donor' vehicle engine running when 'jumping'?
