The Amprobe Digital Megohmmeter, Model# AMB-45 is an insulation tester that checks to see if conductors are leaking current to ground or the shield in a coax, for example. It will not check the output of a modulator, it may actually damage the modulator.

Add a comment with more information:
1) Brand and model number of fan and remote so expert can access product manual. Without product manual, we're guessing. If product manual has a phone number call it.
2) Attach clear in-focus photo of existing switch with all wires for best possible guess.
3) get a tester and find which wire inside the box is hot. Turn off switch and test each black wire to bare ground wire.

Resetting a tripped kitchler low voltage transformer

Model number is not known.
I did not know that Kitchler transformers have a circuit breaker.
Usually they have an override switch.
Did you set the timer to override, what does your product manual say?
Is the transformer humming? Kitchler transformer are supposedly non-audible, but there should be some indicating sound. The humming sound indicates the transformer is working.
Does the unit have photoeye? Cover photoeye with black tape.
Test outlet with circuit analyzer.
Check outlet voltage: if you have 120Volt then output is 10% or 12Volts. If you have reduced voltage, then output is still 10% but might be lower than needed to operate bulbs.
Plug timer into different outlet.
Test output terminals with low voltage tester.
Did you have power outage or nearby lightning strike? Transformers are not protected from surge.
Suggest you contact kitchler. website is useless

Kitchler products are probably warranted through the seller.
Kitchler product manuals are almost non-existent.
Scan your product operating manual and parts list into .pdf format and post on web for others to access.

Wireing diagram do not no were thay go three wires

K4221C photo cell page at Intermatic:

Photocell has black, white and red wires on photocell.
Black goes to Hot from breaker.
White goes to Neutral from breaker box
Red goes to Load (light)

Electricians don't guess, they test.
You should have one wire coming from breaker box, and another set of wires going to light.
Separate wires for testing.
Since you are outdoors, stand on dry boards and tape tester leads to wood sticks to keep hands away from power.
Turn power ON
Test each wire to bare ground wire.
Tester lights up on hot wire. This wire should be black.
Hot wire connects to photocell black

Hot is identified.
Test Hot wire to all wires except bare ground.
Tester lights up on neutral. This wire should be white.
Neutral wire connects to photocell white

Now the other cable goes to Load. This cable has a black and white wire.
Connect photocell red to black Load wire
Connect white Load wire to Neutral, along with photocell white.

Ground wires are twisted together.

New intermatic T101 timer problem - timer is not

Manual override lever is good overall test of T101 120Volt timer.
T101 timer has 3 terminals: A 1 2

See wiring diagram on following link:

Electricians test, they don't guess.
So test your wire:
Separate all wires for testing.
Use ordinary 2 prong tester.
Tape wood sticks to tester leads to keep hands away from power.
Stand on dry boards. Do not hold or touch anything metal.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. 120V circuit has only 1 Hot wire. If you have 2 Hot wires, you might have 240Volt circuit and need T104 timer. If circuit has 1 Hot wire, then that Hot wire must connect to terminal 1.
If you have NO Hot wire, then check circuit breaker.
Hot wire is identified.
Now test Hot wire to all other wires, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire must connect to terminal A.
If you have NO Neutral wire, then additional wiring is needed, or circuit needs further testing to see what type of wiring you are working with.
Bare ground wires connect to green ground screw.

Notice there are small white wires also connected to terminals A and 1. These small white wires power the 120V clock motor. With Hot on terminal 1 and Neutral on terminal A, the clock motor will run, and yellow dial will rotate.

If timer dial does not rotate after connecting Hot ans Neutral, then test voltage across Hot and Neutral to make sure it reads 120V.

Your circuit should have 2 wires remaining.
These wires go to 120Volt load (fan, light, motor)
Connect these two wires to terminals A and 2.
Try manual override.
If Load turns ON-OFF, then timer is wired correctly.
If Load does NOT turn ON-OFF, then reverse Load wires on terminals A and 2.

Add a comment any time.

The manual switch works but the timer does not rotate. The timer knob is properly placeed into the geared drive but the timer motor does not seem to be operating.
Half of the online manual is upside down.

According to the manual, the clock motor that operates the timer requires a separate Neutral wire.
The clock motor is a separate circuit, just like your alarm clock.

The wiring is:
Black-hot-from-breaker connects to timer-black wire
Wire-to-Load connects to timer-red wire

Timer-white wire connects to Neutral.
The Neutrals are white wires twisted together and covered with a wire nut.
Not every box has Neutrals ... in that case, connect timer-white wire to bare copper wire.
Bare copper wires connect back to the Neutral busbar in breaker box.
Attaching your white wire to ground is not code, but it will work.

How to test your wires:
Separate wires
Turn on power
Test each wire to bare ground
Tester lights up on Hot wire from breaker
Now test Hot from breaker to each of the other wires, except ground.
Tester lights up on Neutral

The problem will more than likely be your transformer. To test you can go get a cheap voltage tester from home or hardware store it to the lowest alternating current voltage setting and put the leads across the output of the transformer. Anything less than 12V and your transformer is shot. Its not expensive for a new one either if you just want to swap it out rather than messing with a tester.

Megger testing of wire insulation. what represents a good reading and what is a bad reading. Using a AMB45 (Amprobe) Is an "OL" good or bad?


OL is a good reading, it represents a reading of greater than 400Mohm, with any insulation testing the greater the value the better.

There should be a drain hose that takes the melted ice (water) out the back and down into a pan under the refrigerator where it evaporates. Check inside the lower part of the freezer for a small hole-it needs to be clear to let the water run through the tube and down into the pan. The tube can usually be disconnected behind the unit to clear it out with a wire or hanger. Good luck
