I'm on my 2nd battery in my 1995 Ford Explorer . The battery from the factory lasted
6 and 1/2 years before it got a dead cell and I got a boost and drove to the Ford
dealer and got a new battery which is still fine after 8 years plus
Check alternator output with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running Should read approx. 13.8-14.2 with engine running
Check alternator with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running With engine running reading should be approx. 13.8 - 14.2 volts
Bad alternator? A fully charged battery should read approx. 12.8 without engine running With engine running should read approx. 13.8-14.2 volts
Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving. You can test this by jump starting your car with another car and after your car is running you should be able to disconnect your battery and car should still run off the alternator. If your car stops than your alternator is RS. Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving.

should but what run to long because all power in/on truck running off battery
the reason its still running is because your battery has transferred some juice into it already give life for a short period of time.
Your 12 volt battery should be about 12.5 volts without the engine running. Test and verify it is. Now with the engine running test again, Voltage should now be around 13 to 14 volts. If not, then your battery or alternator are bad. To check a battery try charging it with a battery charger.
put a voltmeter on the battery and test voltage, then start the cycle and check again. A battery at rest should be at about 13 volts, with the engine running it will be at 14 or above. to be sure disconnect the positive battery terminal while running, if there is still good volts there, or the engine does not die it is ok.
Sounds like you may have a bad alternator - check with a voltmeter A fully charged battery should read approx. 12.8 volts without vehicle running With vehicle running reading should be approx. 13.8-14.2 volts
Disconnect the battery.
Check the charging system with a voltmeter to see if it is charging the battery sufficiently A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
first crank the bike. (with battery charger if need be) then disconect the battery while its running. if the bike goes dead this means that the only thing feeding your spark plugs and coil is the juice from the battery and you have problem with the magneto most likely. if the bike remains running after you disconect the battery you should still check the voltage in the battery leads (the wires you disconected, not the battery) with a volt meter. if the system is "charging" it should give you better than 12 volts. these two things should tell you if you have to look further.
