You have to test current by putting multimeter on Amps setting in series with the load - very dangerous and since you are asking question like this I would suggest to get someone experienced to do it for you (not worth risking your life)
If you insist on doing it yourself get someone to supervise (someone with knowledge)

Does anyone repair multimeters?


junk it as the parts would not be available
new ones are now better equipped to handle what you did and the cost of a good unit from places like Jaycar start around $40.00 up
these measure capacitance, resistance , voltage ac/dc, show polarity of the current, test diodes ,measure up to 10 amps current, and a host of other functions including range settings for all readings all of which come in handy for a shade tree mechanic

Can you wire up the heating element in a hot water heater wrong


you can indeed here are the steps to check you eliment

Turn off the breaker inside your main electric panel providing power to the water heater. Most electric water heaters use a 30-amp double-pole circuit breaker.
2 Look for the panels attached with screws to the side of the water heater. Depending on the size of the water heater, you will have one or two panels. Remove the screws from the panels to release them.
3 Remove the insulation you exposed when removing the side panels. Depending on the age of the water heater, the insulation is fiberglass or closed-cell extruded polystyrene foam. Wear safety goggles and gloves when removing fiberglass insulation.
4 Pull the plastic safety cover from the element face. This cover snaps on and off the element and thermostat.
5 Hold a noncontact voltage detector next to the wires connected to the element face, and next to each wire connected to the thermostat. If electricity still is present in the water heater, the voltage detector emits an audible alarm and its light flashes.
6 Loosen the two element screws. Remove the wires from beneath the screws. Make a note of the element wattage printed on the side of the element face.
7 Turn the dial on a multimeter to Rx1k (resistance times 1,000 ohms). Touch one of the screws on the face of the element with one of the multimeter probes; place the remaining probe on the remaining screw. A 3,500-watt element should register 16 ohms, a 4,500-watt element should register between 12 and 13 ohms, and a 5,500-watt element should register between 10 and 11 ohms. Replace the element if it does not register on the multimeter.
8 Leave one of the probes touching one of the screws on the element face. Touch the other probe to any metal part of the water heater. If the multimeter needle moves, the heater element is grounded, and it must be replaced. Make sure you test both screws on the face of the element.
9 Touch each screw with one of the multimeter probes. Place the remaining probe against the metal base attached to the element where it enters the water heater. The element is bad and must be replaced if the needle on the face of the multimeter moves.
10 Attach the wires back to the face of the water heater element. Snap the plastic cover back over the thermostat and the element. Reinstall the insulation and attach the panels to the side of the water tank. Turn the breaker on to the water heater.

Things You Will Need
  • Screwdriver
  • Safety goggles
  • Gloves
  • Noncontact voltage detector

Dear Neil:

Thank you by your request, I hope you are very well.

I am sorry for my delay.

You must proceed with this:

1) Check C. Breaker from your home if tripped, resset , and try again.
2) Check the power cord, for some cable loose or broker, repair or replace the power cord.
3) Now turn on the treadmill, if it does is o.k if doesnot proceed with C.BREAKER of the Treadmill, reset, and try it again.

Of course you must have some DVOM(digital voltmeter) for to Test this.


How to Check AC Volts with a Multimeter


The multimeter is an essential tool for electrical troubleshooting.

A multimeter is a versatile tool for measuring voltage and current. Electricians use multimeters to measure alternating current, or AC, and direct current, or DC, voltages and currents. Many multimeters also measure resistance, capacitance and temperature. For example, an electrician uses the multimeter's AC voltage setting to determine if a wall outlet has power or if a power supply is functioning. This knowledge helps the electrician pinpoint the cause of an electrical problem and select the appropriate repair.
Instructions

1.

    • 1

Plug the black voltage probe into the voltmeter jack marked "COM."

    • 2

Plug the red voltage probe into the voltmeter jack marked "V."

    • 3

Rotate the range selector knob to the highest range setting, which is marked "VAC."

    • 4

Turn the voltmeter on. Slide the power switch to the "ON" position.

    • 5

Touch the probes to the device for which you measure the AC voltage. Use extreme caution. Ensure that the probes do not come into contact with anything but the surface you are measuring.

    • 6

Read the voltmeter's display. Turn the range selector knob to a lower range if voltage is less than the currently selected range

Yes you can use this instrument to measure. It needs to be put on the AC voltage and to be on the highest value. Voltage is measured with a fuse included (be careful). It is better to use a screwdriver tester to find a phase (hot wire). Wires are measured ohmic and should not be turned voltage on(or it may burn the instrument). If you measure current it can short circuit if the installation is under voltage (because of this reason the current is measured in series connection).

Got a 62600 dryer and the power wont come on got power to the unit


Working with live electrical current can be very hazardous. Testing voltage output requires working with electrical current. Do not attempt this measurement without the proper tools and safeguards
.
To measure the voltage at an electrical outlet requires the use of a multimeter. Always test your test equipment for proper operation before use.
Set the multimeter to AC voltage. The markings may appear as VAC, AC V, or a V beneath a wavy line. Choose the AC voltage closest to the voltage you will measure. Standard current in home and businesses in the USA is in the range of 110 to 120 volts. Some circuits used for equipment such as dryers, air conditioners, electric stoves, ovens and other large equipment may use voltage in the range of 220 to 240 volts. These heavy-duty circuits can be identified by their non-standard outlet plugs.
While grasping the insulated portion of the probes (never touch the metal conductor during testing) place one probe into each of the two terminals. The multimeter will display the voltage.
Carefully remove the probes, being careful not to touch the metal part of the probes to anything or each other.
The voltage should typically test in the range of 108 to 121 volts for most circuits. If voltage is higher or lower, professional electrical service may be required.


Good luck;

2005 Hartford HD-125S electrics not working


Hi, Ratbag1488 before testing any electrical component in the Charging System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test because your battery may have 12.5 volts or more but little or zero amperage and must be replaced AGM types more so than lead acid batteries.
1. Battery Test:
The battery needs to be a fully charged and load tested to ensure proper readings, connections need to be clean and tight. If you are not working with a fully charged and functional battery, all other voltage tests will be incorrect. Standing battery Voltage should be 12.5-13.2 DCV.
2. Charging System Voltage Test:
Start motorcycle, measure DC volts across the battery terminals you should have a reading of approximately 13.2-15 DC Volts.
3. Connections and wires:
Inspect the regulator stator plug, and check the battery terminals for connection corrosion. If everything seems to be in order, move on to number 4 below to determine if there's a failed component.
4. Stator Checks/Rotor Check: Each of the following tests isolates the Stator & Rotor. If AC output and resistance test fail and stator test passes then the rotor is at fault (Pull Primary covers and inspect rotor for damage).
5. AC Output Check:
Unplug the regulator plug from the stator start motorcycle and change Voltmeter to AC volts. Probe both stator wires with your meter lead. The motorcycle should be putting out approximately 18-20 ACV per 1,000 rpm. Reading will vary depending on system, check service manual specification
Generic Specs:
22 amp system produces about 19-26 VAC per 1,000 rpm
32 amp system produces about 16-20 VAC per 1,000 rpm
45 amp system produces about 19-26 VAC per 1,000 rpm
Stator Resistance Check:
Switch your multimeter to Ohm x 1 scale. Probe each stator wires with meter leads and check resistance on the meter.
Resistance should be in the range of 0.1-0.5 Ohms. Reading will vary depending on the system, check the service manual for specifications.
Generic Specs:
22 amp system produces about 0.2 to 0.4 ohms
32 amp system produces about 0.1 to 0.2 ohms
45 amp system produces about 0.1 to 0.2 ohms
Stator Ground Check:
Switch your multimeter to Ohm x 1 scale.
Probe each stator wire with your positive lead on the multimeter and the negative to ground.
There should be no continuity to ground on either wire.
If there is continuity your stator is shorted to ground and must be replaced.
5. Regulator Test:
Each of the following tests isolates the regulator only, so if any of these tests fail, the regulator is at fault.
Identifying Wires:
Battery Charge Lead- Wire going from regulator to battery positive.
AC output leads- Wires coming from the Stator to the regulator.
Ground- Wire from Regulator to ground or regulator may be grounded via the physical bolting to chassis.
Regulator Ground Test: Ensure the regulator body is grounded or grounding wire is fastened tightly to a good ground (you should verify this by checking continuity from regulator body to chassis ground).
Fwd/Reverse Bias Test/Diode Test:
This check is testing the Diode function to ensure it is regulating the AC current for the stator into DC Current.
Switch multimeter to Diode Scale.
Place your Multimeter positive lead on each AC output wire.
Place your multimeter negative lead on the battery Charge wire.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the AC output wires and the Positive lead on the Battery Charge Wire. The reading should be Infinite. With your meter on the same setting, place your multimeter positive lead on the regulator ground wire or to the regulator directly, and then place your meter negative lead on the AC output leads.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the regulator ground and the Positive lead on the AC output wires. The reading should be Infinite.
Note: Below is a table to show the readings:
Positive Lead Negative Lead Reading
AC output 1 Battery charge lead Voltage
AC output 2 Battery Charge Lead Voltage
Battery charge lead AC output 1 ?
Battery charge lead AC output 2 ?
Ground AC output 1 Voltage
Ground AC output 2 Voltage
AC output 1 Ground ?
AC output 2 Ground ?
