What's the polarity of my EPC96 H19.6V Drill please? Charger adapter has broken down, Have a multi-meter, but require polarity to

The battery may have failed. You need to add more information so we can determine what your problem is.

test the battery with a multi tester then if there is power your drill is the problem.

i bought a new makita cordless drill in united states of america brought it home to the republic of ireland got a 110 adopter to recharge the battery but it will not hold the charge would it be the flight home have wiped the batterys what do i do?

centre pin on plug socket is usually positive...
think I would **** it and see ....if the replacement charger has a charge light it will probably not light if you have reversed polarity. Had the same problem with VHF portables ...I just cut the wire on new charger and tried both options ..reconnected and a bit of tape...voila.
There is little danger to your drill from getting it wrong as long as a the timing is relatively short.

Hi,

Have you tried removing your battery for a minute then plug it in again?
Check also your charger if it has a voltage output using your multi-meter. the expected voltage you will read is indicated on your chargers name tag in DC volts (observe polarity).

When you press the power button does anything happens to your laptop or nothing happens at all even indicator lights?

Don't forget to rate me...
Thanks..

look for a travel converter or 240v to 110/120v converter usually the adapter will plug into ur outlet and the charger[or whatever] plugs into the adapter and can convert the power down to the lower i have used mine every time i go to europe the adapters cost between 10 and 15 dollars mine is a one piece multi-use 8 different outlet designs- its easier than rewiring the charger

if you have one check the battery and charger with a meter. if there both fine check the prong's on the battery and the power tool. if charger is'nt charging check the fuss in the charger.. good luck let me know.

Center pin is generally positive - outer ring is negative. But you can use a 9v charger just as easily; in fact, the one supplied with the cordless drill is a 9.0v, 200mA output charger.

A commom power problem with laptops. To determine if it is the power socket on the laptop is the problem, plug in the adapter into the laptop and wriggle the plug and look at the charge/power LED on the laptop. If the LED flashes as you wriggle the plug then :-
The problem is the power socket on the laptop, it may caused by a dry solder joint and needs to be resoldered or the power socket may be faulty and needs to be replaced. Either way to fix this, it requires the laptop to be dismantled to get at this power socket. Get a quote to repair, as it could cost a few dollars.
If it is a faulty cord/plug on the power adapter, this can be checked with a multi-meter. When you connect the multi-meter probes to the power plug the voltage should be steady and the reading should be slightly higher then the voltage that is printed on the label on the bottom of the power adapter. If the voltages fluctuates as you wriggle the plug then you have a broken wire in the plug. Replacing the plug would not cost much.

If these tests did not resolve your problem, then you could have a motherboard problem. A replacement motherboard may not be a cost effective solution. It may be better to put your money towards a new laptop.

Look on the charger itself & it will have the correct output voltage & polarity stamped on the charger. Then get a volt meter to verify if the correct output voltage is present. If the volt meter reads less than what is stamped on the charger, then I would recommend replacing the charger at that point.
