Can i use this tester to check for any live wires. im installed a new light fixture on my porch from existing wiring but lights not tuning on
However, I can provide guidance on using a basic voltage tester to check for live wires when troubleshooting a light fixture installation.
Using a Voltage Tester:
Non-Contact Voltage Tester:
If you have a non-contact voltage tester, it's a handy tool for quickly identifying live wires without direct contact. Hold the tester close to the wire insulation or the terminal screws, and it should indicate the presence of voltage without making physical contact.
Contact Voltage Tester:
If you have a contact voltage tester, make sure it's designed for the voltage level you're working with (e.g., 120V for residential electrical systems).
Turn off the strength to the circuit on the circuit breaker or fuse box.
Safety First:
Always prioritize safety. Make sure the power is turned off before working on any electrical components.
Test the Tester:
Test the voltage tester on a known live circuit to ensure it's functioning properly.
Check the Wiring:
Once confirmed, turn off the power to the circuit you are working on.
Use the voltage tester to check each wire connected to the light fixture. Verify that there is voltage on the wires.
Neutral and Hot Wires:
Typically, a light fixture will have a hot wire (usually black) and a neutral wire (usually white). Make positive each wires are linked properly.
Ground Wire:
Check for a ground wire and ensure it's properly connected. Some light fixtures may have a green or bare copper wire for grounding.
Switch Position:
Ensure that the wall switch controlling the light fixture is in the ON position.
Bulb Check:
Confirm that the light bulbs in the fixture are working and properly installed.
Circuit Breaker Check:
Double-check the circuit breaker or fuse for the lighting circuit to make sure it hasn't tripped or blown.

I have a onan 4000 LP generator when I try to start it it starts and then goes dead?
Here are some common troubleshooting steps to help you identify and potentially resolve the problem:
- Fuel Supply:
- Check the LP (propane) fuel supply. Ensure that there is enough propane in the tank.
- Check for any obstructions or kinks in the fuel line.
- Air Intake and Exhaust:
- Make sure the air intake and exhaust are not blocked. Lack of proper ventilation can cause the generator to shut down.
- Choke Position:
- Check the position of the choke. If it's set to "Choke" for starting, make sure to gradually move it to the "Run" position once the generator has started.
- Fault Codes or Indicator Lights:
- Look for any fault codes or indicator lights on the generator control panel. These can provide clues about specific issues.
- Oil Level:
- Check the oil level in the generator. Some generators have a safety feature that shuts them down if the oil level is too low.
- Spark Plug:
- Inspect the spark plug for fouling or damage. If needed, clean or replace the spark plug.
- Fuel System Issues:
- Inspect the fuel system for any leaks or issues. LP generators may have a fuel filter that needs to be checked and, if necessary, replaced.
- Carburetor:
- The carburetor may need cleaning or adjustment. If it's clogged, it can lead to stalling issues.
- Battery Voltage:
- Ensure that the generator's battery has sufficient voltage. A weak or dead battery can affect the starting process.
- Generator Load:
- If the generator is under a heavy load, it may shut down. Try starting it without any load and then gradually add loads.

How can I clear this because I can't recharge my prepaid meter.
rF Con means there is no RF connection.
Try this;
* Press the Back arrow on the keypad - this step is to refresh the UIU ( the device)
* Type # 75 # - this is to check the signal strength
If it does not go back to the normal display
*Type # 80 # - this is to refresh the meter
Then lastly you can repair the meter and the UIU by # 36 #
The above steps will work better if you are outside the house because the meters uses the radio frequency connection
The above error will occur in instances of bad weather conditions or if there is load shedding or power failure
If the problem persists after trying the above you may contact the municipality or the service provider."
