Why did the red flashing alarm light stop flashing? Alarm and remote working fine


Most likely the 12 volt led light burned out.. all bulbs LED too don't last.. Find the 2 wires usually Black and red and check for 12 volts with the alarm set and if you have 12 volts,. you need to go to radio shack and see if they still have 1. 2 volt led bulbs.. Good luck.

COLEMAN INVERTER PMP1200 JUST BEEPS WHEN TURNED ON


It is most likely the low voltage alarm. Suggest connecting when the car is running with no load (110 volts not connected). If the alarm continues turn the unit off and on to reset.

Hope this helps?

Inverter Protection Features
• Short Circuit Protection. The inverter will automatically shut down until short is removed.
• Low Voltage Alarm. An alarm will sound when the voltage from the battery discharges to 10.5 +/- 0.5 volts DC. This is an indication that the battery needs to be recharged.
• Over Voltage Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the input exceeds 16.5 +/- 1 volt DC.
• Under Voltage Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the input is less than 10.0 +/- 0.5 volts DC.
• Overload Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the continuous draw of the equipment being operated exceeds 1200 watts or the surge draw of the equipment exceeds 2400 watts.
• Thermal Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the circuit temperature exceeds 150° F

While I was charging the power chair all the indicater lights came on and with a block lights went from all green to 2 red flashing lights, w/ 2 red lights flashing I stopped and shut it off 4 five se


Two red lights blinking means the electronics on the chair think the batteries are low. Test the voltage on the holes marked 1 and 3. Hole 1 is positive and hole 3 is negative. Your meter must be set on DC volts and the meter leads must be in Common and Volts. If your meter has to have the voltage range set, put it on 200vdc. The red lights will blink if the voltage is approximately 22.5vdc or less. The green lights turn on about 24.5vdc or higher.

How do I know it's charging


if you can get your hands on a volt meter attach the meter to the charger clamps, red to red and black to black, turn the volt meter to DC volts (20V scale on most) and turn on the charger. You should be reading at least 12V.

Pheonix plus batery flat,charged up,now it is mobile but all i have on dial is single red flashing led.


John the red flashing light indicates a low battery When you charge the battery your charger should be showing a red light for power and a yellow light. When the batteries are fully charged you should show a red and green light on the charger. Now if you have a voltmeter plug the leads into the two outter holes of the charger port located under the front of the joystick.Without the charger plugged in you will be reading the battery voltage. Fully charged it should read 27-30 volts if you are only reading 20-24 volts then the batteries are low. If you have an onboard charger plug it in and you should read the charger voltage of 29-32 + volts If you aren't getting that voltage then you have a bad charger if you are getting the charger voltage then you have bad batteries and they need to be replaced Hope this helps you

The battery backup beeps and the service light is on. The battery tests good with a volt meter


This is battery related. On top of your unit is a battery pack with three colored led lights. You can tell what is going on by looking at these. This information is in your manual or here it is.
GREEN LED: All systems are normal. A solid LED light indicates the batteries are fully charged. A flashing LED indicates the batteries are being charged. NOTE: Batteries do not have to be fully charged to operate the motor unit. YELLOW LED: The motor unit has lost power and is operating off of the BBU. A solid LED with beep, sounding approximately every 2 seconds, indicates the motor unit is activating the door and is operating off of the BBU. A flashing LED with beep, sounding every 30 seconds, indicates batteries are low. Once the power is restored the BBU will recharge. This is indicated by a flashing green LED. RED LED: An error has been detected and the BBU will automatically shut off. The BBU will attempt to restart by reconnecting to the batteries. If the error is still present it will shut itself off again. This process will repeat every 5 minutes or until the error has been resolved. This is used to prevent further draining of the batteries. If a red LED remains on when the power is restored, and is accompanied by a beep sounding every 30 seconds, please call for service.

I really don't have any idea as to what you're talking about here other than a battery and maybe a charger. Seems as if you're saying that you have a 12 volt 1.5 amp automatic battery charger connected to a 12 volt, 8.5amph battery but the red light on your charger is blinking. The blinking red light indicates that the charger is not seeing a proper connection such as crossed polarity connection or simply a poor connection. You say that the battery voltage has dropped from 12.5 volts to 9.1 volts with the charger connected. If this is the case, the battery is badly discharged and the charger is not charging the battery for some reason. The charger may be bad but check the connections to make certain they are correct and good. If they are, I'd replace the charger.

Good luck

I have been charging my 2 million candle power spot light for last 2 days but full battery charge indicator (red light) does not flash yet. the led white light is working but the main lamp doesn't work....


It should take 10-12 hours, any longer the battery is no good, you can test the battery using a Volt Meter, the battery should be reading 12 volts, any less and the battery will need to be replaced. You can order a new one from Black and Decker, they purchased Vector in 2006, here is the link;

Upon power up, 3 red LEDs flashing rapidly continously, no power.


The control systems on power mobility equipment have a "prevent" circuit that immobilizes the equipment while it is plugged into a charger, so folks won't take off with it plugged into the wall outlet. When you turn it on when plugged into a charger, the display will flash constantly, or sweep constantly, depending on the manufacturer. This is normal. Your off-board charger should have a red light to indicate power to the charger, and another light for the charge status. Yellowish means it is charging, when it turns green, you are fully charged. If the status light is green all the time, that is an indication that the charger is not functioning properly, or that the batteries are below a chargeable state. Check charger output, which should be 26-28 volts dc, and each battery should show at least a 12 volt reading, but around 13.5 volts with a full charge. If one or both of the batteries drops below 12 volts after a short period of time, it's time for a fresh pair. Fully charge new ones before using the chair.

Charger red lite flashing. Camera comes on for one second and shuts off


Hello,
Here's a copy from the owners manual:
■ Charging LED 
Red LED is on = Being charged 
Red LED is blinking = Charging error 
Green LED is on = Carging is complete


● If the charge indicator blinks as red, it indicates a battery charging error.
- The battery is not properly inserted
- The terminals of battery are dirty or damaged
If the battery is inserted properly and the charge indicator continues to blink, contact the
nearest Samsung Camera Service Center.


Another charging error is when the batteries are so depleted, they won't charge up to 100% anymore = red light doesn't go out and remains on for too long, means get a new battery.
