Sounds like one or both of the batteries has a high internal resistance. Bad batteries, perhaps? Have you LOAD tested or tested for internal resistance? Could be why charger is shutting off so soon.
Voltage isn't the only test for these types of batteries.

Unit goes to "overload" and quits


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

In your case it is obviously not heat, speaker load or excessive volume at the moment.

You could unplug it then turn it upside down and shake it to see if something metallic is rattling around inside it. Maybe open it up and sniff for burnt components, but even if you see something obvious and replace it you migh not know what the original cause for failure was, so you may just be wasting time and sacrificing new parts.

I have changed the backup battery, i have charged it for about 22 hours, but when i turn off the electrical supply, it goes off! ( the ups) MUSTEK POWERMUST 800


Remove batts, Check battery connector, fuse and batt volts, if you have dummy load (car headlight etc) check batts are working and measure voltage under load.

Also check if UPS needs to be told there are new batts read manual or check support for maker.

Let me know what you find, hope this helps

Thanks for using FixYa

Overload Red button is on even after pressing reset button @ back


Try unplugging some equipment from the UPS. The total load should be less than 865 W. Printers and scanners often are culprits.Some gaming desktop computers can have a power supply that will be too much for this UPS. (I've found that even having the printer on the surge only part of the UPS can be a problem. I have the printer on a separate surge protector.)

Since the overload is new, did you add any equipment to the UPS recently or upgrade components?

If you reduce the load, and the problem continues, the UPS may have a fault in the circuitry. If it is under warranty, contact APC.

I hope this helps.

(I have replaced APC units after 3+ years when they can't properly recharge the battery - with a new battery. The symptoms are 1) getting a overload when a small load is on the UPS. Small load - desk lamp, 13" TV or 2) not keeping the item on when the power goes off.)

Overload prblem of inverter


PLEASE MAKE SURE THAT ALL THE LOAD CONNECTED TO THE INVERTER IS NOT MORE THAN ITS CAPACITY, BUT IF IT SHOWS OVERLOAD WITHOUT ANY LOAD CONNECTED TO IT MIT IS POSSIBLE THAT THE OVER LOAD CONTROL IS BAD

Battery will not fully charge but will run with partial charge


Two things can be wrong, first your batts may be old and need new ones. Have them load tested at an auto part store. Most powerchairs use two 12 volt batts. If you batts are good you should have between 12.5 and 13.5 volts on a surface charge and 11.5 to 12.5 on a load test charge. Second, if you had your chair stored away for a couple of months then your batts died and need to be replaced. If you are luck a "boost charge" might work. If you are planing to keep it stored for months at a time, you must charge the chair once every couple of weeks to keep batts fresh.

Could be a bad overload protector in the motor. Some machines have a circuit where the machine rapid advances to the end when the motor overload protector kicks in. This would also make sense that it started happening in the Spin cycle when the motor draws the highest voltage.

Electricity goes off when machine start turning


it may be the motor if you unplug the motor then try again,if the power doesnt turn off then its the motor.also check for water leaks

PROTECTION MODE


The unit may be experiencing an overload caused by a short circuit, internally or externally. Try disconnecting all the speakers, then turning up the volume. If nothing happens, connect one speaker at a time and turn up the volume to see if you get more sound. You may have a speaker that has shorted internally and this will help you discover the bad one. However, if when you have all the speakers disconnected, and the unit still goes into protection mode with the volume up, then there is a problem with the unit itself.

Hope this helps, and please rate my advice, good OR bad.

Good luck!
