When testing the 6-Pin PCIe connector with a multimeter what should the voltage read?
Wiki User
∙ 13y ago
The 6pin PCIe connector supplies 12v DC on pins 1, 2(optional), and 3 (yellow wires). The other pins are ground.

When testing for current draw your digital multimeter should be set on?
When testing the current draw your digital multimeter should be set on the current.
Why diac should be tested with power supply and cannot be tested with digital multimeter?
It's like a spark plug, it needs higher voltage to transmit the power.
What megohm reading should you get testing a low voltage cable?
Greater than 1 Megohm
How much voltage for 132kv UG cable high voltage testing?
it depends on the specification,,,,,,in saudi arabia as per sec standards 152kv voltage should be applied for a period of one hour.
If you attempted to read the voltage across a car battery with the multimeter accidentally in ammeter mode?
A multimeter when used on voltage, has a very high resistance/impedance to limit the current flowing through it. However when you set it to read current, it has a very small resistance to encourage the current to flow through the metre so can be measured. So ig you put a multimeter across a voltage source (in parrallel) when its set to current, you will normally destroy the metre. Although more expensive metres will have a fuse to protect the instrument should this occur. Hope this helps Always switch back, should you do this on the mains, you can quite easily set the metre on fire!! CB Eng

When measuring voltage how should test probes be connected?
First connect the positive terminal of the voltage line to positive terminal of multimeter and negative to negative terminal of multimeter. Select voltage in multimeter and measure the voltage
Which multimeter setting to test power supply of a computer?
That depends on what you're testing it for. You would mostly use the volt meter settings to test for proper voltage output at the connectors coming out of the power supply. After verifying the expected volt output from a suspect connector, You should, in case you are wrong or a short is present, start with the highest voltage AC settings first and then reduce to lower settings and DC to confirm proper outputs.
Which mode is use in digital multimeter for testing of diode?
A: For a digital meter to test a diode it must have a scale for resistance for it to work, If not a 1.25 v cell with series limiting resistor will work. If you measure across the diode the reading should be .7 volts reverse the cell polarity then the diode voltage should be 1.25 v .7v is forward voltage 1.25 is reverse voltage.
1991 Cherokee no spark?
make sure ignition primary is connected to distributor or coil pack, whichever is used. if it is connected and still no spark, unplug primary connector. use a grounded testlight or a multimeter set on dc volts to check for voltage. if voltage is present, test light will glow or meter will give a digital reading. make sure key is turned to on while testing. check for secondary spark by removing a plug and grounding it on the engine while cranking. a strong spark should be present. if not, replace dirty plugs or open plug wires. to check plug wire, remove it and set the multimeter on ohms it should read 0 meaning wire is not open. make sure distributor has no cracked cap or corroded parts. refer to a manual for coil pack testing terminals. Unplug and reconnect the CPS connector at the rear of the engine. If it starts, plan on replacing it soon, as it will fail again.
How do you test a 220 volt breaker?
You will need a multimeter to check a 220 volt breaker. You should unplug appliances that go to that particular breaker. Use the multimeter at the breaker to check the voltage. If it shows 220, then the breaker is okay. If it doesn't, then the breaker is no good.

How can you know if your alternator is bad?
Check the voltage output at the battery posts with a multimeter set to DC voltage in the 20 volt range engine idling. You should get from 13.5 to 16 volts. Any more or less and the alternator is bad.

Why would your AC not come on when you turn the knob?
You either have a bad switch or you need to check your fuse or relay for your a/c. To check your switch: you need a multimeter or voltmeter. You'll need to get to the back of your switch, keep it plugged in and find your power wire to the switch. Then put the positive end of the voltmeter in the back of the connector into the power(don't push to hard or you'll damage the connector). Then put the negative end of the voltmeter on a good ground on your frame or something that touches your frame. You should get a voltage reading of 12 volts. If there's no voltage than somethings wrong with the wiring up to your switch. If there is voltage, than you need a new switch.
