Is there an easy way to troubleshoot an electrical problem?
There is an easy, straightforward way to approach electrical troubleshooting, and it’s astonishing how many people don’t know it.
What should I do if my electric motor is not working?
If a device—say, an electric motor—isn’t working, first determine if voltage is reaching it when the switch that powers the device is turned on.
Do you need a wiring diagram to troubleshoot a car?
It is close to catechism in the automotive electrical world that 1) you need a wiring diagram to begin troubleshooting, and 2) most electrical problems are due to bad grounds, whose locations are listed on the wiring diagram.
Why does my car turn over but not start?
Car will not start,,,car will turn over but not start…often happens when car is hot from abient tempature. The car will only start intermittently. You have to turn it on several times before it turns on

What to do if your car has a voltage drop?
If voltage is present at the device’s positive terminal, test for continuity between the wire to the device’s negative terminal and ground (first the body of the car, and then the negative battery terminal). If it passes those tests, conduct a voltage drop test to check for a high resistance failure.
How can I find out if my electrical track is bad?
Next, connect the constant current source to the rails with the jumpers. Use the digital voltmeter to measure the voltage across the rails. The meter should be set to read millivolts. Then slowly “walk” the voltmeter leads down the track. The reading should be very low, in the millivolt range.
Sometimes troubleshooting is easy and extremely obvious – like a switch that was forgotten about or yes – the darn light bulb was just burnt out. You may even discover that a GFCI receptacle or breaker was tripped. There have been times when the tripped GFCI Plug was behind a pile of boxes in the garage and no one ever knew there was a plug there.
What to do if you have a loose electrical connection?
Make sure these receptacle circuits are turned off before removing the cover plate and receptacle for inspection. Make sure your connections are well made. A loose connection will also cause shorts and create burnt wires which could result in a potential fire hazard.
