It's not unusual for Dewalt triggers to go bad and it appears you have correctly tested the trigger. You can test the motor by wiring it directly to the battery but hold on to it and only give it a short burst of power so it doesn't spin out of the case. Dewalt triggers are fairly easy to find online but shop around, they're not cheap.

Depending on how old or more to the point how many times you have already charged the battery, it may be worn out. All rechargeable batteries do reach a point where they won't charge up anymore. If you have fully discharged the battery and tried to fully charge it up again and it won't take a charge or only lasts a few minutes on a charge it may be time to recycle it and buy a new one.

Go to http://servicenet.dewalt.com/, put your model number in the "find parts" search box. A couple models of the DC825 come up, select yours and on the right side of the product page you can download the parts breakdown and manual.

Rechargeable batteries do have a lifespan, they won't recharge forever. If you have fully discharged the batteries then fully recharged them and they still don't have full power or they only last a couple minutes then they are done. If they won't charge or the charger shows them as defective, the only fix is to replace them.

it sounds like you have a problem with the switch or battery. Try cleaning the battery contacts first and then remove the battery and look into the tool and see if the switch contacts are bent not allowing battery to seat firmly. If that is OK then I would think that you need a new switch. MAKE note of how you remove it because it is polarity sensitive. Let me know if you need more assistance.

you can try and go to dewaltservicenet.com and under the left-hand side you will find an area to download manuals and breakdowns, click on this and then go to manuals in the next page, click to view or download. Let me know if you need more assistance.

I am thinking the switch or motor is bad, check the switch first. you can locate parts at dewaltservicenet.com. Make a wiring diagram before removing anything, these parts are polarity sensitive.

I would start out blowing out the chuck with high pressure air because you might have some saw dust or other item causing friction that is allowing the chuck to move. Then I would spray a lot of WD-40 down the chuck to float any contaiminents up.

sounds like you need a new motor, you can buy one from dewaltservicenet.com or ereplacementparts.com

Grab the drill head as hard as you can put the drill on drill setting and the highest number setting and put it reverse

It's probably the switch; mine judders and works kind of. Slight burning smell coming from it, dismantled it to discover that the switch has started to burn out, so far no luck finding a replacement.........

JCB are totally useless, no help from their support phone number!

Hi,
The spark you have seen inside is from the carbon brush that is arching the electric current and don't worry thats normal!

hi, put some wd40 down it, or some crc,

Hi,
The only way to tell if you can fix it is to take the drill apart...
Look for two wires melted together...my guess is that they got too hot and melted together inside the drill... separate and insulate and you should be fine...

could be 1 of 2 problems, the motor or the switch, I would think more the motor. you can get some idea of what the cost would be by going to dewaltservicenet.com and typing in your model number for the parts listing. But also keep in mind that Dewalt has a MAX service rate that they will rebuild the tool up to the MAX rate for it, that includes batterys (or it used to include them)
