Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.
The other possibility is the charging circuit may be faulty.

Low beams dont work and only one high beam works


Do you know how to do voltage drop testing ? Leave the blubs in there sockets turn the low beams on , measure voltage on the power side , LH low beam yellow with black stripe an for the RH low beam dark blue wire . If you have battery voltage there, power side is good . Then check ground side both are yellow wires , test with lights on . if you see 6 volts , 12 volts .anything more then .03 millivolts you have a ground side problem . The lights ground through the light switch .
Low Beam
Voltage to the headlamp switch is available at all times from the HDLP SW fuse 7 through CKT 1940 (ORN). When the headlamp switch is turned to the HDLP position, the headlamp power relay coil is energized through CKT 352 (WHT). A signal is also sent to the body control module (BCM) that the headlamp switch is ON. When the headlamp switch is in the AUTO or PARK position, the ambient light sensor (located in the right speaker grill) senses either daylight or darkness and sends the signal to the BCM. When the Ambient Light Sensor detects a dark condition, the BCM produces a signal that will energize the headlamp power relay through CKT 352. The relay coil is grounded through terminal F7 connector 2 of the underhood fuse block to CKT 350 (BLK) to G102. When the headlamp power relay is energized the relay supplies power to the LT HDLP and RT HDLP fuses. The RH low beam headlamp receives current through CKT 198 (DK BLU) from the RT HDLP fuse. The LH low beam headlamp receives current through CKT 712 (YEL/BLK) from the LT HDLP fuse. Both headlamp low beam bulbs are grounded by CKT 524 (PPL) through the underhood fuse block to the multifunction switch (low position) contacts through CKT 10 (YEL) to the headlamp grounding relay in the body relay block through the normally closed contacts to CKT 1850 (BLK) to G200.

1. Four beeps every 30seconds (On Battery LED will be illuminated)
This alarm indicates that the Battery PowerSupplied outlets are now supplying battery power as opposed to power from theutility. If the UPS determines that the input utility power is unsafe for yourcomputer equipment, the UPS will switch to battery power.

2. Continuous Beeping (On Battery LED will beilluminated)
This alarm indicates that a Low Batterycondition has been reached and that the UPS will soon shutdown. Once the UPStransfers to On Battery operation, it can only stay on battery for a limitedamount of time. The UPS will sound this alarm about two minutes before thebatteries are totally exhausted. Once exhausted, the UPS will shutdown and turnoff its output power to your equipment. If you hear this tone you shouldimmediately shutdown your computer to prevent data loss or corruption.

3. Continuous Beeps for 30 seconds (BackUPS OFFICE 250 and 280 ONLY)
This alarm indicates the unit has detected anOverload condition after it has performed a self-test during start-up.

I have an Symmetra RM APC and there is an amber light showing and a beeping about every 30 seconds.


Hi Ewiesemann,

The amber light on the UPS usually means that the unit is 'on battery' -- meaning that input power is affected. Check to make sure that unit is plugged in and check to make sure that a breaker on a panel feeding the UPS power hasn't tripped.

Hope this helps.

I have had my whirlpool dryer about 4yrs + (geq9800pw2) has always worked fine. Last week it started tripping ckt breaker toward the end of drying cycle. As of this morning, it blows ckt breaker...


leave off the oven and a/c breakers and plug dryer and reset the breaker. if not tripping occurs then one at a time trip back the oven first. if no trip then trip off again and trip the a/c. if no trip then trip the oven back. if trip you may have a wire problem. if dryer trip any way then possibly you have a short in dryer. check the heating element wires,power cord at the dryer side(terminal block).

APC ES-350 won't turn on; all I see is a blinking light.


Try looking for a small circuit breaker on the side that says "press to reset" - you could have tripped it accidentally when you unplugged the iPod.  Also, try pressing and holding the UPS power switch for 10-15 seconds.  That should force a power on as well.

Unit is switching to battery power for now reason.


Any UPS monitors the incoming AC level to determine if it is needed or not.  I think the APC unit doesn't know any more when it is needed; it's sick.

APC Smart-UPS 1400 no power


Better late than never...

The older Smart UPS models are peculiar in the way that they appear dead (will not power on) if the battery is completely bad.

Replace the battery, and the UPS should come back to life.
