@LoneTinaja Месяц назад

If a donor vehicle is running when giving a jump start the excess voltage going into the recipient vehicle causes the circuit board in the ECU to overheat. If the excess heat doesn't kill the ECU, it at least degrades it. Excess voltage causing overheating can also degrade resistors, capacitors, diodes in other electronics.

Never knew two alternators could spin against each other. Usually they spin with each other (meaning they increase the amperage output capacity but still remain within a 12-volt system). They don't short each other out.

@AshSiddiq-id4ly 4 месяца назад

Scottie is a typical old fashioned mechanic...he wouldn't understand electronics/electrics if it smacked his bottom for him. You want the donor car running before you connect the jump cables and you want to rev the donor car to normal driving revs before trying to start the other car

@thomasschwarting5108 4 месяца назад

Usually the car being jumped, the cables are being diconnected as soon as it's running. I don't really see the issue here. The systems are connected for a very short time. I see your point, but people have been doing it for years. I know, you'll say cars have changed and yes they have, but for those couple moments that cars systems are connected, can any real damage occur in such a short period of time?

@mrfixitusa6165 4 месяца назад

I think what he's saying is, if there is a problem in the electrical system of the car being jumped, it can cause damage to your alternator if you have it running when you engage the starter of the dead car. I always try to check the voltage with my multimeter, to make sure I'm getting the full 14 volts through the cables first, and to the battery second, before I ever even bother trying to crank the dead car. Because most of the time a jump fails, it's because there's a poor/incomplete connection, and there's no way to really know that without checking the voltage with a meter. You can waste a lot of time waiting for a battery to charge, when you're not getting full power flow, through the cable to the dead battery.

@jeffquinlan4064 Год назад

Yeah, I'm also curious as to why this is bad. The amp draw shouldn't do anything bad to the donor alternator. The alternators don't make alternating current that would be out of sync with each other, they make dc current. The batteries do a majority of the load. I suppose you could say that a dead battery could be a sign of other things that could be seriously wrong and you wouldn't want that to affect your vehicle. I don't get it yet.

The difference between Alternators and DC Generators is that the Alternator only gives you 1/2 the sinewave. The DC Generator might rectify the output to give you DC. The DC Alternator puts out DC but it will Pulse, which is bad for Electronics and your meter thinks it's AC. A DC Generator has Brushes that wears out. So they use a Brushless AC Generator and rectify it to give a DC output. With an Alternator they just chop off 1/2 the wave. To save money.

@dubmob151 Год назад

It's really best to charge the dead battery offline to bring it back to full charge, because if the battery is really bad and draws an excessive current from the started car's charging system, it could overload it from the excessive charge current and cause damage to it. But, being an unlikely situation and in interests of time, no one will ever go that route and simply start and go. Millions of people can't be wrong 😉
