1999 gmc safari van wipers wont work


check fuse, then run a ground wire to the wiper motor and ensure the ground is good. if the wipers start to work then the motor just needs a permanent ground connected to it. if it doesn`t work then check for power at the motor if you have power then tap the motor with a hammer to see if it starts if so then the motor is bad.

Where can I find a 240v Bosch 11240 SDS Max Rotary Hammer drill that I can take and use in Ghana


You'll be hard pressed to find one that doesn't run on 110v. You might be able to look on ebay and buy something from the UK like this for example:
http://www.ebay.com/itm/Bosch-GBH4-32DFR-NEW-Multidrill-4Kg-Rotary-Hammer-With-Accessories-240V-/160648807099?pt=UK_Home_Garden_PowerTools_SM&hash=item25676a42bb

Or you could just get a power adapter. Make sure they will work for the amount of amps that the tool will be pulling.

Fuse Panel iagramfordcontourlx1


use a test light with the circuits turned on as some fuse won`t show being good unless the circuit is on to send power through the fuse.if the fuses are good then run a separate ground wire to the wiper motor and make sure you have a good connection at both ends.if it starts to work then you will have to connect a ground wire to the wiper motor.if it doesn`t work then you can tap the motor with a small hammer with it turned on if it starts to work then the motor will have to be replaced as there is an internal problem with it,

Hi, I hope both of my problems are related. The chisel is "stuck" and won't release. Also, the unit does not "hammer". The motor runs and when I select drill the unit spins. I...


you need to get that chisel out. If it was hammering with it before the end of the chisel might have broken and not coming into contact with the striker, if it did not then the end of the chisel might be damaged not allowing it to seat fully, either way get the chisel out and put in a regular bit and it will probably work.

Motor works and spins but as soon as the drill touches the wall drill stops but motor keeps going.


Check the speed switch on top - sometimes it doesn't fully seat in the 1 or 2 position. Switch it to the opposite setting, run it, then switch back, until it seats properly. Also check the clutch control ring for the same issue.

Windshield wiper will not work for a 2006 ford taurusjohnwalku16-umail@yahoo.com


check the fuses in the fuse panel(under dash drivers side),with wiper motor on tap the motor with a hammer to see if it starts,if it does then the motor has a bad spot in it like a bad starter.if this doesn`t work try attaching a ground wire to the body of the wiper motor just with your hand(make sure you have good contact at both ends of the wire)if this works then permenatly attach the wire as this indicates the wiper has a bad ground.also check the plug connection to the motor to see for good connection and no corrosion.

I want to run this drill at the end of a 250' AWG 10 extension cord. How much voltage drop can this tool tolerate?


Most ac motors will run with a +/- 10%. Quick calculations say you drop will only be 2.3%. You should be just fine.

Dewalt d25940k is a demolition hammer whith drill too?


No, the D25940K is not a Rotary Hammer. It is just a Demolition Hammer. (Jack Hammer). You can turn the chuck to adjust how your bit sits but that is it. Follow this link to the manual for this tool. http://www.dewaltservicenet.com/documents/English/Instruction%20Manual/581735-00,D25940.pdf
