Circuit tester not lighting up... Fuses good


Test your 'tester' on a known live circuit first.
This way you can rule out if it is your tester that is the problem before digging away at the dash.

Pull out the fuse, test it with a multimeter on the ohms setting. Sometimes visually checking we can miss a break in the fuse.

Circuit tester when plugged into 3 pronged plug, comes up with 2 green lights and 1 yellow light. There is no code on other side of tester to access this problem


Circuit analyzer does not show all possible problems, and tester might be defective.
Use analyzer on other outlets.
Buy another circuit analyzer.
Buy a multimeter at local hardware, and test for voltage, and continuity, and compare with known outlet that are functioning correctly.
For example outlet may be 240Volt instead of 120V.
Copy following links to see typical circuit analyzer and code:

Not getting power when plugged in.


Hi,you may as well checked socket connecting the source.Now try to diagnose the problem.Try to connect other appliances using the source where dishwashers initially connected.If it didn't work there is a problem with your socket.If it does work.You can check the continuity of the circuit of yuor dishwasher using an ELECTRICAL TESTER/MULTITESTER.Set it to OHMS then connect both ends of the tester .If reading moves.or tester pointer moves at least to the maximum value or at least 90% of it.It means it does work.no problem with the continuityI but If it moves more than its maximum amount short circuit happened within the circuit..Continuity will test if short circuit happend, if there is a continues connection within the circuit .It tests if IC's inside the circuit has not been short circuited due to overheating..hope this helps..

Need operating instructions


T 101 Intermatic timer is 120Volt timer that will not work on 240Volt circuits

T-101 instruction manual
T-101 Wiring diagram:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

To set timer:
Lift and rotate yellow dial until current time is lined up with silver pointer

To set ON OFF times:
Timer comes with 2 sets of ON and OFF trippers
Attach trippers on yellow dial at the time you want timer to turn ON and OFF
Minimum time period is 1 hour.
For 1 hour, attach ON OFF trippers next to each other.

To wire timer:
There are 3 terminals: A 1 2
Black Hot wire from circuit breaker connects to terminal 1
Black wire going to Load (lights fan motor) connects to terminal 2
White neural wires connect to Terminal A
Ground wires connect to green grounding screw

If the two black wires are on the wrong pole, the clock motor will not rotate, but the manual override will turn lights on and off

How to test for Hot wire:
Stand on dry boards
Wear dry clothes
Tape tester leads to wood sticks so hands are away from electricity
Separate all wires
Turn on power
Test each wire to bare ground wire
Tester lights up on Hot wire
120Volt circuit will have a single Hot wire
240Volt circuit will have two Hot wires

How to test for Neutral wire
240V circuit will not have Neutral wire
120V circuit has Neutral wire
Make sure circuit has only 1 Hot wire as described above
Test Hot wire to each white wire
Tester lights up on Neutral

I have a bad circuit (S type 15 amps fuse) that blows every fuse I put in it. My four way voltage tester says that it runs at 110 volts. Does this mean that I have a ground or short circuit problem? If so,...


please describe what type of device or circuitry you are having the fuse repeatedly blow so that I have a better idea of understanding your specific circumstance. A constant blown fuse normally indicates a short somewhere or an overloaded circuit somewhere. The type of tester you need is a ground fault receptacle tester you can purchase them at any hardware/electrical supply store for between $10-15 that tester when plugged in will show whether you wiring is correctly installed or not. please respond with further info and I can be of more assistance

Understanding Outlet Circuit Test Results


open ground=ground wire (green) is not connected to the circuit box ground or to the earth ground.
(there should have steel rod place in the ground by the local electric company, and gtound wire is connected to that rod).
Open Neutral= same as open ground. unless you are testing 240V, which have 2 hot (110v) and a neutral (0V).
Open Hot= open 110v line (black)
hot/ground reversed= if you understand the above, then this sould be self explaintory.
same a hot/neu. reverse.

if you don't understand how electric wiring works, My suggestion is to stay out.

Usage Repair


the current reading on a tester is independent of the battery in the tester. The battery is there to provide a tiny amount of current so you can read the resistance on a circuit in ohms.

What probably happened is that the useage selector switch was in the wrong position when a measurement was made for voltage of other and being in the current position created a short and the current measurement circuit was burned out.

for more details, please follow up with questions/comments
