Jump starting how to jump start with dead battery

When Connecting jump leads ALWAYS Positive first, (Red), Negative last, (Black).
When Removing jump leads ALWAYS Negative first, (Black) and Positive last, (Red).
ALWAYS make sure you DON'T touch the negative to the positive at any time! (Loads of sparks and you risk damaging the battery).
Safest way I have found is this.
With the engine on BOTH vehicles turned OFF. Connect up to the flat battery first, then connect to the good battery. ONLY start the vehicle with the good battery. Wait 2 or 3 minutes to let some charge cross to the dead battery then start the vehicle with the dead battery.
The dead battery will need to be fully charged as soon as possible.

taking the battery leads of a running alternator is one sure way of destroying the alternator
if you think a battery is dead you have it load tested and replaced if it doesn't meet the test
what you should be doing is taking the vehicle to an accredited auto electrician and having the battery load tested and the alternator and voltage regulator professionally tested for proper operation

double posted, why?
JUMPS OK
AFTER JUMP WORKS AND DRIVING, AND STOP AND KEY OFF
IT WILL NOT CRANK.
did i guess right?
that means ,
check all fuses first. even the alt fuse (large)
1-battery bad? #1 top failure all cars.
2-Charge system bad. (is the charge/ batt warn lamp glowing when running car, bingo.????

3-or phantom drains. (if no crank just after stall then it not this) if drains while sleeping yes.

the tests are easy, a dirt cheap voltmeter
13.3v to 15v running is good charge system.
if 12v and falling not.

if the battery is bad, the charge system can shut down, so, the best practice is to try a know
good battery out of 2nd car, do you have battery to barrow, this is TOP CHOICE< not thinner wallet.

if the good battery fails then the charge system is failing (note I said system and not a part)
or the belt missing or slipping to the alternator.

btw the 4.3L PCM runs the alternator
PCM is engine brain.
btww, same true 2.2l engine.
the regulator is in the PCM.

so is the charge/bat lamp in cluster
on key on, lamp test
the jump start it , it runs
does the charge./batt.lamp go out.
id be all over that lamp, costs nothing to look.

Dealer ! Battery Disconnect or Replacement Problems Dead battery same as disconnected battery . Electronics go night - night !

place the positive lead from the jump battery to the positive terminal of the dead battery. take the negative lead from the jump battery and place it on the engine or other metal point--- NOT TO THE NEGATIVE TERMINAL OF THE BATTERY-- If you do then you run a real risk of a power surge that will fry the ECM
However with a dead battery if the cells are failed then the power from the jump battery will probably feed the dead short in the dead battery and it may not work
Best have a load test done on the dead battery to see if it is faulty (cold weather) or just flat

Change the battery. Newer batteries sometimes go all at once, and are so dead even a jump start won't work. It has happened to me twice. Once you put in the new battery check the alt output with a volt meter should read about 14.5 volts at the battery. If it does problem solved just reset the clock, radio etc.

Probably the battery. Take it the chain auto parts place and they will test it for you.

Well if you cant jump start it thats a good sign that the battery is dead so replace it and you should be fine, and another way you can try is hook the battery up to a charger overnight and if it doesnt hold its charge then you will know if its dead or not.

Some German cars have anti-theft device inside to make it useless to steal...check at the dealership to see if jumping the battery will activate this(the car thinks its being stolen) .
