Sounds as if battery has internal short. Also have charging system checked. If doing yourself check amperage also. Charging volts and no amps wont work or overcharging. Over charging will ruin a new battery. Also make sure you have clean solid connections between cable ends and battery. Take cables off and clean very good poor contacts will give false readings when checking system.

2010 flhx battery fully charged but starter drags bad then clicks. Jumped power from car, still does the same thing.


Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12 volts or better after charging.
3. Make sure all connections are clean and tight especially the negative cable at both ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor. Good luck

Battery wont charge, battery/ABS/SRS/BRAKE lights come on while driving and flicker. voltage increases to dash lights/fan speed/headlights periodically.


Get a volt meter, start your car and see how many volts your car is producing while running. Should be around 14 volts. May want to watch the meter for a while since your electric seems to fluctuate. Most voltage regulators are internal of your alternator. If you are getting a lot more or less than 14 volts while running, replace the alternator. If it is not charging, voltage will drop as vehicle runs, until battery is dead.

My riding lawn mower turns over but not fast enough to fire cant figure out whats wrong please help


I assume an electric start. Slow cranking could be low battery voltage or capacity. Check battery voltage with a digital volt meter. It should be 12.6 volts. (Unless it is a 6 volt battery which should read 6.3V when charged.) Under 11 volts it is dead.

To check capacity see how much the battery voltage drops while cranking. It shouldn't drop more than a volt.

Battery dead. recharged, car started. drove 20 miles. parked 8 hrs. drove back home. after parking 15 minutes car wont start. Which is problem, alternator or battery?


Don't know.
You would need to have both components tested. It could be a dead cell in the battery. Or a bad connection. If the alternator were at fault it should discharge when the engine is running and slowly go dead.

Need Homelite Mower UT13122 wiring schematic to check switch problem. Battery fully charged


Check the switch for current flow with and without the key. Then make sure the ground switch is disengaging when you pull the handle.Possible stretched cable.

Tractor wont start unless I jump it


How old is the battery? When you get it started put a digital volt meter across the battery terminals and with the throttle about 1/2 open check the voltage. If should be over 13 volts DC if your charging system is working ok. If it is over 13 volts your battery has probably just given up. Lawn mower batteries are only good for 2-3 years. A trickle charger can extend the life if used.

I hope this helps.

1985 dodge powerwagon, lights went dim driving home now wont start, just replaced battery 6 months ago. starter clicked at first then nothing.


The alternator may not be charging the battery. Jump start it, and use a volt meter at the battery, red lead to positive and black to neg. The meter should read between 13 and almost 15 volts, any lower than 13 volts, the alternator is no good. (this is done with vehicle running).

Husqvarna Mdl YTH2448 Riding Mower - Electric PTO Not Working


It sounds like your charge system is not working. If you jump the battery the engine will run with a weak battery but the pto clutch needs a strong battery to stay engaged.Try this to test it,after you jump it leav the jumper cables hooked up and try to engage the blade clutch,if it runs it is either a battery that wont take a charge or a charge system not working. If you put a volt meter on the battery while the engine is running and the voltage is 13 volts the charge system is working and the battery is bad.

Battery wont stay charged


HAVE YOU CHECKED THE CHARGING SYSTEM? YOU COULD HAVE A BAD VOLTAGE REGULATOR. ITS REAL SIMPLE TO DO.START THE MOWER,PUT IT AT FULL THROTTLE.TURN A MULTI-METER TO VOLTS AND TOUCH THE BATTERY.YOU SHOULD READ 13.5-14.6 VOLTS.IF NOT GOOD CHANCE THE VOLTAGE REGULATOR IS NO GOOD.
