After jumping my landcruiser...it runs while connected to the jumper cables, but when i disconnect the cables...it dies automatically...is this a battery or alternator problem?
Quick check for a failed alternator: Take a screw driver that can be attracted by a magnet. With the car running (and presumably with the alternater spinning), touch the screwdriver to the middle of the rear of the alternator. If the screwdriver is attracted, then the alternator is at least producing current. If there is NO attraction then the alternator is definately dead.
Hi,if all your connections are good,it sounds like the alternator. I would take the battery out and charge it,then load test it.If it checks good.Take the alternator to autozone or advance and have it checked.Good Luck!!!
