Does Jumping Another Car Affect Battery

A common mistake which can lead to damaging your own battery when trying to jump someone elses is parking your cars so close together that they actually touch.

Does jumping another car affect battery. Be very aware of the polarity of the jumper leads when jump starting a vehicle with a flat battery as many an ECU has been damaged by short circuiting the jumper leads. If another vehicle isnt available for the jump start use one to jump start by connecting it to the dead battery following the steps above. Your instructor may have had that thought when he saw some arcing as the jumper cables were being connected.

If your engine wont spin over the battery may be the problem. Been doing carmotorcycle repairs for few years. The reason for 2 if battery cant absorb energy removing jump leads can lead to a voltage spike and this is of course harmful.

However there are a few things to note. Multiple blown diodes on the rectifier is a confirmation that an external event has short-circuited the diodes. This usually happens either because the jumper cables are too short or because one or both vehicles batteries are located in awkward locations in the engine compartment.

Since winter I helped friends about 15-20 jump starts to be exact and that was only 5 months so about 4 times a month or once a week on average. You would have same effect if you disconnect the battery of a car while engine is running. Second if the jump is done incorrectly you can fry computers fuses or.

A jump is only a temporary fix until you can replace or connect the battery to a charger. Modern batteries are meant to deliver a hefty charge each time they start the car so using it to start another car isnt that much different. This can be a dangerous myth especially if you frequently drive in rural areas.
