The speed switch on my dewalt drill got switched while the trigger was engaged. I've noticed a flash in the back of the drill when it stops now from full operation. Is that normal and I didn't notice

The speed switch on top may be in between speeds. Try it in a different speed. If not the top switch, the the trigger may be bad. Does reverse work?

This replacement battery was a great find. We searched for batteries for our Dewalt drill and this is the only site(www.drill-battery.co.uk) that had it and at a good price. Works fantastic and is a great deal.

Change the trigger.Look at eReplacementParts.com and the parts diagrams.

Thumbs back!

Your speed switch is between gears, pull the trigger lightly and slide the speed switch back and fourth until it is fully engaged. Also turn the clutch setting all the way down then all the way back to lock it is not uncommon for them to get dodgy.

Check the speed selector switch on top of the drill... it can get dirty and not fully engage. Cycle the swatch a few times back and forth and stop in your desired indent (1, 2, 3) when you feel a real positive click.

If the battery is OK then the problem will be in the variable speed trigger switch.

Ok, first check to see if the trigger lockout has been engaged, it's a small level at the top of the trigger ( I know this sounds silly, but it happens sometimes). Flip it side to side to see if you can hear the selector moving the switch inside the drill. If the selector moves freely without engaging the switch, you'll have to disassembly the drill housing to put the selector back into the lever so it will work.

Just take out all the screws in the housing and carefully remove the one side and look at the switch lever and make sure it is inside the slide selector lever.

If that isn't the issue, I'm afraid that the electric trigger/switch has failed and this isn't a part that can be disassembled and repaired by a DIY'er. I've attempted it when mine failed and found out it's a sealed unit and wrapped in a copper heat shield that dissapates heat when the variable speed is utilized and you end up destroying the switch housing in the process.

However, any DeWalt authorized repair center can do the repair for around $20 +/-, and if your drill is under the 3 year warranty period, it should be a free, warranty repair. Just contact DeWalt's customer service or your local Authorized Service Center (listed in phone book usually), or check the link for finding one near you.

If you noticed this sound the first time you tried the drill, it is noise of the armature brake.  This noise is normal and not a problem at all.  Michael Mittelsdorf
