I brought a three wheel scooter for my wife and the next day i had to buy two new batterys for it as the other ones did not hold their charge but when i put the new ones in and charged them it still will not charge as on the scooter there are three lights on it they are red yellow and green the green light tells you that the scooter is fully charged but the green will not light up and it as not blown as if i put it into neutral all the lights will flash and i charged it overnight and took it out in the morning it whent flat in about 5 min of putting the key in so you see it as had two new batterys in it and it seems to be the same as before if not worse and the green light always comes on the charger

Re: batterys will not hold charge
Right off the top of my head I would suspect the charging circuit. The way to check this is to measure the voltage at the batteries while they are on charge. The voltage reading when they are supposed to be charging should be higher that what you would read at the batteries when they are not charging.
These charging circuits are not complicated and any electrician type should be able to trouble shoot the circuit and find the problem

I've broken a couple of Rotozips. They say there is a replacement part available from the company, but I found it much easier to just replace it, as they have hidden springs and little parts that are real easy to lose ( I tried to fix 2 of them and now have lots of spare parts for the next one I break!). I paid $25.00 and about $10.00 for shipping for the button and lost the spring, and the button is very model specific - meaning it will only work on that model! Hope this helps!!
I have the same problem. I have 2 ,1 on each of my daily chop saws. I have had them for about 10 years so I will just buy a new one. For the record a few times I had a wood chips blocking the lens.
surley nothing wrong with fixing old one.If bearing is a easy one to get.Another thing to consider how much does he use it if for his every day work new would give less prob and warrenty.lookup make online should find part from the maker.hope helps
The shaft threads seemed to be stripped and you may have to get a set of Torx bits or if not then one bit for the torx screws to take them off. If the threads are stripped on the shaft then you may have to replace it. Ken S.
I looked at a breakdown and there is no clip. Sometimes the bearing is tough to pull out of the gearcase. Do you have a dead blow hammer? Sometimes I have to apply pressure (pulling) to the armature and tap the gearcase make sure that I hit a solid thick piece of it and generally it will jump out of there. Also in the past with the fan bearing on the armature it is so close to fan that you have to crush it in a vise and use a bearing splitter to remove the inner race, or if you buy the parts from Dewalt you might take it with you and ask them to remove and press the new ones on. Let me know if this doesn't work and I will research further.
Mine did the same thing. I think it's a bad contact situation. I ended cleaning all the contact springs in the battery compartments and also putting a small dab of silicon on each battery before re-fitting the cover plate. This made sure the batteries were nice and snug in their housings. Make sure the batteries all have have the positive symbol (+) upwards when you refit them. You can also check the centrifugal switch. This is located under a triangular plastic cover. If you hold the batteries in place with your thumb, you can gently push the tiny weight against its contact and the laser should light up. DON'T LOOK DIRECTLY INTO THE LASER WHILE YOU DO THIS!!! This worked for me but I can't give any guarantees but, hey, what have you got to lose? Good luck.
take a pair of good vise grips and hook onto blade tightly, slide uo against back braket. that will hold the blade from spinning while you remove the nut, try bumping your ratchet/ wrench w/ a rubber mallet or hammer. hope this helps
