The motor works, the battery seems fine (has 1.02 V.+-). When I plug the cord in and turn the shaver on there is a tiny buzz like a stalled motor, but that isn't it. I applied a 1.5 V. battery to the motor for a second and it spins just fine.
Where can I get a schematic? I suspect either the transformer or a diode (because I get no reading either way across the diode).
You might try the original type battery (rechargable) Batteries Plus has them for less than 3 dollars, and they will solder the leads to the battery FREE! If you were lucky enought to get the 4501 apart, you may have problems getting it back together. Be sure front and back panels are free from the sides and it wont go back together unless you put the TOP snaps in first. Good luck...I got mine going for $ 2.78...

Start by removing the foil and cutter. Then remove the swivel frame by removing the two tiny screws on each side of the inside of the swivel frame. To open the shaver you will first need to remove the two round screw covers on the bottom. Then remove screws. You can then gently pry the two halves apart from the bottom
to open the shaver you will need to remove the two round screw covers on the bottom. Then remove the screws underneath. Next, remomve the foil and cutters and then remove the swivel frame be taking out the tiny screw on each side. Pay attention to which way the swivel frame goes on.
You can now seperate the front and back by gently prying apart at the bottom. Inside you will be able to lift out the circuit board. For easier replacement, it is sometimes suggested that you use a modified installation technique. This is to break the tabs off of the old batteries rather than unsoldering them from the circuit board. This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can then solder the tabs from the new batteries to the old existing tabs.
Reassemble in reverse order
This problem is usually cause by a worn out shaving head (foil and cutters). Braun suggests that you change these every 12-18 months for best performance. You will find replacements at shaveroutlet.com for your model 4501 Braun shaver. See link below.
It is also possible that your shaver is running too slowly due to an old battery if you've never replaced it. If you require a new battery, it can also be ordered from shaveroutlet.com. See link below.
To change the battery you will need to be able to do a little soldering. Open the shaver by removing the two round screw covers on the bottom of the shaver and then the screws underneath. You will also need to remove the foil and cutters and then the swivel frame which is attached by two tiny screws. Once removed, you will be able to open the shaver from the bottom and seperate the front and back. Remove the circuit board to easily get to the battery.
Note: The tabs on this type battery will work for most applications however they may be slightly different than some original equipment. For these instances, it is sometimes suggested that you use a modified installation technique. This is to break the tabs off of the old batteries rather that removing them from the circuit board. This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can them solder the tabs from the new batteries to the old existing tabs
If working properly, model 5510 will work either from the internal rechargeable batteries or directly from the cord. If your shaver no longer recharges, it needs to have the rechargeable batteries replaced.
Your battery has degraded to the point that it won't hold a charge and also won't pass voltage/current and thus doesn't work even when plugged into the outlet.
You need to replace the rechargeable batteries to get your razor working again. If you want to do this yourself, check my other posts on how to access the internal circuit board and unsoldering the faulty battery and replacing it with a new one.
You can also contact Electric Shaver Service at 1-888-476-1785 to get an estimate for them to do the repair for you. They are reliable and quick with repairs usually done within a week from reciept.
There are 2 removable plastic plates on either side of the power entry connector> Pry these off with a knife and remove the 2 screws. Next slide the razor out of it's case. The batteries are soldered in.
