Dewalt DC920KA Heavy Duty Xrp 18V Cordless Drill/Driver - Answered Questions & Fixed issues

This is indicating the battery is too hot to charge, usually after coming off the tool right after some hard work. During the charging process the battey heats up so if you charge a hot battery, thereby making it hotter, you shorten the lifespan of the battery considerably. If you are getting a hot/cold pack delay indication on the charger, it should automatically start charging once the battery has cooled down sufficently.

Most likely you have a bad switch - the other issue can be worn brushes or brushes that are getting hung up in the brush tubes.

most likely the switch is bad . you can find a break down and buy the part from ereplacement.com

There may be a short in the motor or wiring, or the gearbox is broken or otherwise seized up. Dewalt provides replacements for most parts at reasonable prices, so it's worth taking the drill apart to find out what is going on. I suspect you will find damaged wiring inside due to overheating; you may be able to identify the problem by seeing where the wire insulation is charred or melted. Unless you have a good drill of the same model so you can compare electrical resistance, it's a bit hard to ID a bad motor with an ohmmeter. However, you can try visual and olfactory inspection - if it looks and smells burned, it probably is. You still should check the transmission to make sure it isn't the source of the problem.

Its is about a 2 years modified the XRP chucks In Netherlands the model 950 is not QS made for europe but all the XRP machines have had a special solide looking Chuck For the original Chuck there was a special tool to remove the chuck the gearbox must be open to and a special N119912 a complete unit of repair tools to remove the chuck and replace , BUT the new modificated repair is by get a normal standard keyless chuck , asked them for about the modification because of the older repair tools and chuck http://www.2helpu.com/world/map.aspx it's about much more cheaper to choose for modification the N119912 is possible renumbered thats possible the right same tool because of the model DCD 950 is not selled in Netherlands . the DCD945 instead of but it means the same kind of modification .

Tighten chuck.

You may have a failing capacitor on the secondary side of charger power supply circuitry. The output voltage will be low or have a lot of ripple; this would cause the error detected. Pictured below is a bad electrolytic capacitor next to several good ones (this is not from a battery charger). Notice how the top is bulged upward instead of being flat - it indicates pressure caused by the capacitor burning out. There are other failures that could cause this error code, but this one is highly probable.

please clear the contact of the battery and charger, charge the battery again. If still no help, please use a good battery to see if it is the problem of the Dewalt DC920KA battery or the charger.

Yes, when a battery is being used for a long time, you need to let it cool down and take it to charged. Although there is many fast charger now, but in order to protect the battery, I recommend you to buy a second battery for replace. And, if you do not know where to find the right one? Here is some suggestion for your Dewalt DC920KA Battery

won;t come on all the time

if its like my DC925,you have to remove front of trans. toward chuck! its a plastic piece with a s.s. flat spring washer. if washer falls out install from bottom of plastic when removed from trans. bearings stand in gear grooves. make sure if nut falls out match 1 with 1!

sound normal you smell carbon burning and spark came in that as well

When a Dewalt charger is showing a fast blinking red light it means the battery is no longer chargeable. It may be because of a bad cell or short inside the battery. Whatever the reason the charger will not charge the battery and it needs to be replaced.

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.
