The inductor component has broken off the pcb inside
I have identified a component which has dropped of the main pcb inside my dewalt light, it is a dewalt dc527. It is called an inductor but I am unable to locate a part number anywhere. Please please can you help.

Re: The inductor component has broken off the pcb inside
DeWalt Service Net does not show this individual part. What I would try is to contact the nearest service center and ask if they have a scrap one that you can get for parts or maybe try Radio Shack and see if they can match it up. Good Luck. Dave

It sounds like you need a new charger I'm afraid. If you want to double check though, take the housing apart (4x security torx screws in the underside corners) and check the little glass fuse on the pcb. If either main fuse or glass one is blown you have a problem with the board and it's not worth repairing. If both fuses are ok I would suggest you might have a dry solder or broken leg on one of the pcb components. You could possibly resolder it if you can find it and it has enough contact left.
remove dash to the bulb components (the layer of dash with only bulbs[looks complicated]) turn dash lights on and identify wich bulbs are not working, replace them with the correct bulbs. if this is unsuccesfull find the connection from the bulbs to the wire and also the connection from the wire to switch. ensure the components inside the connextions are clean(pull apart and check for rust, dust, dirt ect..) you can buy connection cleaner from most car orrientated shops.
Had exactly the same scenario. Must be a production flaw that L2 sticks to the GPS piggypacked board. Looked into another TT and found a 100 (µH assumed) on the same spot for this backlight P/S. Took an old Vodaphone/Arcor DSL Modem apart and found three coils 101, 2R2 and 100 ...... The 100 is working fine - had to shift it aside by some jumper wires. Light is on again.
Go to Dewaltservicenet.com and type in your model number in the middle of the page at the bottom. From there you should be able to download a schematic and some of the parts are component parts and don't have a lot of replacement items. It sounds like you broke the clutch or gearcase and both are components.
L2 is a Surface Mount Technology (SMT) inductor. Component marks by convention: L inductor, C capacitor, R resistor, F fuse, D diode, Q transistor, X crystal (xtal), U Integrated Circuit (IC).
L2 is probably a wire through some bulk ferrite for EMI filtering from the power controllers/invertors/CPU/GPU to stop the battery broadcasting the system hash/noise far & wide.
Holding the original L2 inplace while attempting to power up the device worked, but soldering it in didn't. A scavenged similarly sized & shaped L marked component from an old harddrive PCB - from the 5 volt line off the molex power connector - worked fine. Paul Coucher
L2 inductor comes out sometimes when dropped and the DS keeps in fixed amber light when charger is plugged in. But you found it fast so good luck. Its pretty sure your DS will work again after soldering the L2 again in its place near the power switch. Just get the battery and charger out before doing anything to avoid a blown fuse also.
