clock kits

because the clock in my car has stopped working, i pulled the clock out and I have a 3pc. auto electrical tester kit without any instruction. Help please.

Cars operate on Direct Current aka DC. The tester should have a setting to test voltage on a DC circuit. The symbol should be something like V= (the Alternating current AC symbol has a wavey line in it) Take one of the leads to whatever you're testing and the other to a ground- the frame, a screw, anything metal usually works. Read your meter and you should be around 12 volts, 12.15 or 12.25 are not uncommon.

If you don't know how to test the voltage, check the fuse, it will be marked on the fuse block or look in your manual.

If you do use the meter, put the Black probe to ground and the Red to your hot wire, set your meter to 20 v (volts) most are marked 20 - 200 - 1000 (on the DC scale)

Also its not impossible to see 13.5 to 15 volts in your battery.

(at fully charged)

Hopefully your tool kit will include a 12 volt test light.

The alligator end of "the test light should be connected to chassis ground. This can be the negative battery terminal, or any solid, non-painted, metal nut or bolt in the vehicle. When the pointed end or probe of the test light touches +12 volts, the bulb will illuminate."

I don't know what a 3pc. tester is. Get a cheap 12 volt tester and put the aligator clip on grounded part of the dashboard and test the leads to see if you have a hot lead and a good ground to the clock. It's probably the clock.

Your question needs to be clarified.
