Connect the negative lead from the multimeter to the positive lead you removed from the battery

Connect the Negative Lead from the Multimeter to the Positive Lead you removed from the Battery. The multimeter charges the capacitor.

Make sure the Positive Lead you removed from the battery does not touch anything grounded like the car frame etc.

Connect the negative lead from the multimeter to the positive lead you removed from the battery. Connect the Negative Lead from the Multimeter to the Positive Lead you removed from the Battery. You should now see current drain measured in Amps. Move to the lower Amp setting on your multimeter if the current is lower than the setting on the Multimeter Low setting.

Connect the Negative Lead from the Multimeter to the Positive Lead you removed from the Battery. You should now see current drain measured in Amps. Move to the lower Amp setting on your multimeter if the current is lower than the setting on the Multimeter Low setting.

Connect the positive lead of the multimeter to the anode terminal and the negative lead of the multimeter to the cathode of SCR. Now connect the gate through a wire to the anode. If you recall this is the forward conduction mode of the SCR.

The SCR must be turn on. The resistance measured across anode and cathode should be zero. Loosen the battery cable on the positive pole of the battery but leave it connected.

Set your multimeter to DC AMPS 10A scale. Hold the red meter probe on the positive battery pole. Hold the black meter probe on the outer part of the positive cable connected to the battery.

If you suspect it might be assembled wrong just check it with a voltage source of which you know which pole is the positive and which the negative. Connect the positive to the red lead and the negative to the black lead. If the reading is positive red is for positive.

Turn on the digital multimeter DMM to the setting for DC volts measurement. Make sure the negative black lead is plugged into the COM terminal and the positive red lead is plugged into the V terminal as shown in the picture. COM stands for common or in other words the termin al that is the point of reference for other terminals.

The free lightbulb lead is then connected to the negative side of the battery using wire. Current will flow from the battery to the multimeter and then into the lightbulb. Measuring the current through a lightbulb by attaching a multimeter in series.

Current flow is represented by the yellow arrows. One lead from the digital multimeter is connected to the metal washer and the other lead is connected to the negative terminal of the battery holder. With the DMMs positive red lead touch each of the conductors in the tray and record your findings.

And you can accidentally hit that body with the positive lead. So connecting the lead first is safer. Whole car except a few parts like the positive pole are connected.

Any mistake with the other lead will lead to a short. And car batteries are very good at shorts. You really do not want this.

Connect the alligator clips. There should be a black clip and a red clip. Take the red or positive cable and attach it to the positive terminal of the battery to be charged.

Once you have ensured you have a solid connection connect the black negative wire to your ground location located in step 2. Connect the leads to meter input jacks. Insert the known battery to the meter leads momentarily.

Note which lead is attached to the positive side of the battery and which is the negative -. If the meter reads negative voltage on the digital readout or the needle goes down scale on the analog meter remove. Connect the Positive Multimeter Lead to the Battery Positive terminal.

Make sure the Positive Lead you removed from the battery does not touch anything grounded like the car frame etc. Connect the Negative Lead from the Multimeter to the Positive Lead you removed from the Battery. You should now see current drain measured in Amps.

I removed the battery and did some cleaningre-grounding of terminals and thought Id take a multimeter reading for continuity between the positive and negative terminals to ensure there are no shorts one would not expect there to be continuity between the positive and negative terminals. Connecting Base to the collector. In this step you will need to keep your digital multimeter positive lead to the BASE B and then place your digital multimeter negative lead to the COLLECTOR C.

For a properly functioning NPN transistor your digital multimeter should. Connect the Negative Lead from the Multimeter to the Positive Lead you removed from the Battery. You should now see current drain measured in Amps.

Move to the lower Amp setting on your multimeter if the current is lower than the setting on the Multimeter Low setting. It is certainly possible that you have continuity even with the alternator removed. Things like clocks digital radios with memory alarm system and even some modules always pull power from the battery when the vehicle is turned off.

That will be why you see continuity they are essentially turned on all the time. Place the Red lead into the red inlet and Black lead into the black inlet of the multimeter. The other ends of both the leads connect to positive and negative ends of the battery.

Turn on the Fluke 87 voltmeter and press the minmax button. It will show the battery strength suppose 128volts. Now start the vehicle and turn it off.

I got a new multimeter in today and i wanted to test some batteries. I plugged the positive lead into the DC10A and the negative into the COM. I went to test a Battery Station 3V 123A.

I switched the dial to DCV and connected the leads. Almost immediately the battery started to get warm. I removed the leads as soon as i felt the battery heating up.

This is a simple way to find negative wires and positive wires on a 12 volt system. This is a simple way to find negative wires and positive wires on a 12 volt system. Now connect the other end of the multimeters red probe to the capacitors positive terminal.

Following this connect the negative terminal of the capacitor with the black probe of the multimeter. In case the capacitor is working well the multimeter will show0 initially. The multimeter charges the capacitor.

Attach the negative black lead from the digital multimeter DMM to the negative terminal of the battery holder using another jumper cable. 8 Set your DMM to the 20 DCV DC Volts setting. 9 Using the red lead test the voltage readings of your conductors.

A Touch the negative conductor. This should result in a zero reading. B Touch the positive conductor.

Make sure to connect the red multimeter lead to the positive battery terminal and the black multimeter lead to the negative battery terminal. A reading of around 12 volts will tell you that your. To confirm this hypothesis I flipped the battery leads around and found further evidence this may be true.

So it appears that if you connect a multimeter postive lead to positive and negative to negative on the circuit under test the meter will give a positive measurement. If the connections are reversed you will get a negative voltage reading.
