I have a Bruno SRE 2700 chairlift and the batteries are not charging.

sounds like the back-up batteries are totally discharged and the charger is not charging them. either old batteries that need replacing or baterry charger not working

Hi Flaggy. I know it's been almost 5 years but did you ever get this fixed? I have the same issue with a Bruno 3000. It will go up or down a very short distance stop and beep 4 times. Hope you have an answer for me. Thinking it may be a bad switch or relay. Thanks.

1. No red light? Fuse replacement may be required. Follow instructions for a self-test.
2. Does the yellow light come on when the chair is parked against the charging contacts? Bad connection between wire and battery or over discharged battery.

When the red light is on it is to indicate that the charger is getting power from the wall outlet. If there is a second light that normally comes on Green when charging pay close attention to it when you first plug the charger in. See if it blinks even once then turns off. If it does that means the charger is not seeing any battery voltage at the plug that goes into the chair. If the green light does not blink at all then it usually means the charger is defective. Also most wheelchair battery chargers will not charge the batteries if the chair is to dead to even turn on.

Stuart iy\ts indicating low battery voltage charge the batteries and see if it goes away if it doesn't then the batteries need replacing or your charge is not working correctly If after charging overnite when you get up in the morning the charger should have a green light on and the battery level should be full. If after just a bit it goes to the red flashing light then your batteries are bad and need replacing. If the chair is less than 6 months old then the batteries are under warranty and your provider(where you got your chair) must replace them at no cost Hope this helps

After you changed the batteries, did the power chair sit unused for several weeks? It sounds more like a battery or fuse issue than a charger issue. If there are blinking lights when you try to turn the power chair on (not while attached to the charger), or it comes on then goes back off by itself quickly, there may be something else going on.
1- The green light on the charger is telling you that the batteries are not accepting any more power, either they are fully charged or they have oxidized/gone solid from sitting without being put on the charger for too long.
2-The scrolling lights on the controller when the charger is plugged in just confirms that the chair is connected to the charger, so it sounds like everything is connected properly and working. The horn will work fine when it is attached to the charger as it is getting power from the wall outlet.
3- If it was a fuse issue, the lights would not come on at all when the charger is NOT attached, even after the battery has been fully charged, which is what it sounds like is going on. The fuses can blow if you operate the chair on a slick surface or one of the drive tires spin out. The batteries will be fully charged but because the circuit is not complete, the chair will not power on.

I recommend checking the fuses and changing them if necessary. You are in luck because this is a relatively easy and inexpensive fix as they are standard automotive fuses found at any auto parts store or even Walmart for around $2 each (you need 2). The fuses are located inside the gray battery covers under the seat, attached to the leads connected to the battery cables. The straps holding the covers on the batteries are tight, you may want to use a flat head screwdriver to help release the clips. While you are down there, inspect the tread on the tires, if it is worn or slick it may need to be replaced for safety.
I hope this information is helpful to you- good luck!

If you plug the charger into the wall, turn on the power switch and the light comes on, the charger should be working properly. Here is a way to test it-
Attach the charger that came with the power chair to the power chair controller firmly and turn the power chair on, while the charger is running. What should happen:the lights on the controller will scroll back and forth. If this does NOT happen and you can confirm the charger is turned on, the charger handle is fully seated inside the controller receptacle and the wall outlet has power, then the charger may have a problem and needs to be replaced.

If the charger is OK, then there may be a problem with the batteries. Here are some sypmtoms:
1-You connect the charger but the light on the charger never goes red, it just stays green.
2-You connect the charger but the light goes from red to green VERY fast.
3-The charger light goes from red to green but when you disconnect the charger and press the power button on the controller, you only have one flashing red light, or the batteries drain within just a few minutes of use.
4-The power chair has been stored or sitting idle for several months.
5- The power chair has been connected to the charger 24-7 for several months.
Any of the above examples indicates that the batteries are oxidized or damaged and will most likely need to be replaced. The MPV5 takes two, U1 12 volt 33 amp batteries which can be purchased at any battery warehouse store like Interstate Batteries or Batteries Plus.
Good luck!
