That is telling you that your alternator is putting out way to much power and is over charging your battery. There are a few remedies to solve such a issue. One is to replace the ground wire going from the battery to the engine block wire a thicker wire. The second is to replace the Positive wire and down grade it that runs from the battery to the alternator. That last option is to replace the alternator. Alternators can have really only a few problems and the most common is of course just not charging the system at all. The second most common is over charging the system and causing the issue you that you are having. Basically your alternator is throwing out to much volts and needs to be kicked down a notch by one of the options that I gave you. Of course going with the new wiring is cheaper then replacing the alternator but that is of course a possibility for you to explore.

Kubota B 1700 not charging


With everything connected and the engine running, you should see a charging voltage of about 13.5 ~ 15 VDC on the battery terminals. Engine off and and lights / or some other load on the battery should show around 12.5 VDC.

If the 14 ~ 15 VDC charge voltage is present when running, and the battery fails to start the engine; it could indicate a poor connection at the battery posts, dead or failing cell(s) or failing starter.

Have a look at the video below - even though it's about cars charging systems, it applies. Good luck!

My 1999 Chrysler LHS battery drained why is this happening


Tons of possibilities here. Corrosion on terminals builds up over time, causing higher resistance for the electricity going back into the battery from the alternator, causing it to charge more slowly. Moisture (or moisture in dirt) on top of the battery can cause a slow discharge between the poles (worse in humid areas). Short circuits (from bare wires, corroded connectors, etc.). Devices such as phone chargers plugged into power outlets that stay on when the key is off (some do, some do not). Interior lights left on. Remember, also, that alternator recharging will typically not take a maintenance free battery to 100% charge once it has been severely discharged. That means that, even though the car may seem to start fine, it may reach the point of turning the engine slowly (or not at all) much more quickly. It will only reach 100% again if trickle charged (with a battery charger). Probably 4 out of 5 of my battery issues have been solved with a good terminal cleaning and an overnight trickle charge, and my batteries rarely last less than 5 years. My truck battery is still going strong at 9 years. Regardless, though, batteries eventually stop charging, even expensive ones. Hope it turns out to be something simple.

It sounds like you have a defective alternator. The diode in the alternator my be bad and therefore not charging the battery. Have your mechanic test the alternator to confirm that that is the problem. If not the alternator, than your battery may be bad and not able to hold a charge. How old is your battery? More than 4 years old?

check the condition and tension of the drive belt. You say there is nothing wrong with the charging system yet the battery light comes on which indicates that there is something wrong. Check for loose battery terminals . Have the alternator checked for a failed diode in the rectifier.

Just changed my battery, my indicator lights and headlights come on even with the old battery, which was 8 years old, but I don't get any power. Do you think its the starter or altinator


What indicator lights? the headlights should come on when they are turned on. If the battery light is on, the alternator isn't charging the battery. I dont know what power your not getting??

13.2 volts is all your tired old battery can hold.anything above the 12 volts it's rated at indicates it's charging OK.it may increase again,but nothing beats new.consider a battery tender to keep it fresh if it sits for long periods.
