Question about Drills
I have a Delta shopmaster wood workers kit. I have not used it that much and when I went to charge the battery I noticed it would not charge. I tried to diagnose the electronic problem (along with a friend who fixes this stuff) and the cause of the problem was indeterminable because we had no schematic of what we were supposed to read on the ouput. There is power but when you plug in the battery it disappears.
Carefully take the charger apart - I had the same problem - use an allan wrench to take the charger apart - and on the circuit board is a fuse 4A 250 volt - my was blown - replace it and it should work - mine blew most likely from either water or dropping it. You have to carefully remove the fuse - they have tried to glue it in place but it will come out of the holder and the new one will go in easily.

Using a voltmeter on DC check the pos and neg terminals in the charger. It should read more than what the battery is rated if its quick charge. If not, it should read slightly lower than 18. If so, it sounds like the battery is bad. How old is it? DeWalt/PC/Delta has a pretty good warranty program. Lemme know. Please rate me

I have the same problem with my 18V Delta. Yellow power light is on, stick either battery on and all LEDs go off (pre-charging) but it NEVER goes into charging. Limited use on the batteries, strange that both exhibit this behavior at the same time. Fuse is fine, removed and tested. I see 18.1V across two terminals, 7.5V across another two, third combination is 25V. One battery shows 10.6V, another is 8.6V. Both have been discharged and sitting for more than a year now.

It's likely the battery. .. do a quick recharge to the battery using leads to a car battery. . A quick spark cleans the iods within the rechargeable battery which is just a series of batteries linked together. .. any dirty contact prevents recharging. .. after a quick spark. . place the newly cleaned battery on its charger and it should start charging.

I have the same problem, and I find out that one of the resistor was loose and getting really hot and burning the board. I'm not sure whats the value of it, because the colors got erase. I hope this can be replace and hopefully it works....

Well i have had the exact same problem, i plug in the charger and the yellow power light comes on
i slide in the battery and all lights go dead as if in the precharge mode but as above it never ever goes into charge mode . the last time i went to use this kit i was able to slide the battery back and forth on the charger until the yellow red combo , indicating chareg came on very tedious tho. this seems like a reasonable recall item if you ask me, does anyone know of the fix for this?

Check to see if the battery contact in side of the battery pack is lose. my charger burnt one of mine into on both batteries.
