How do you check a grounded coil?
Bench Test (Coil Wire is Uninstalled)
- Connect your ohmmeter or multimeter to the primary studs of the coil. When you look at the coil, the primary studs will be sticking out the top and look something like two bolts or poles.
- Make note of the reading on the ohmmeter.
- Connect the ohmmeter to the secondary winding.
Is the ignition coil the same as the ground wire?
In other words, turning off the key is the same as touching the end of the ground wire from the ignition module to the mower frame. You have answered the question in a way that doesn’t make sense to me.
How to test the power transistor and ignition coil?
Connect the black lead of the LED light to the wire identified with the number 1 in the photo. NOTE: The power transistor must remain connected to its electrical connector for this test to work. You’ll need to use a back probe or a wire-piercing probe to access the signal in the wire. You can see an example of this tool here: Wire Piercing Probe.
Do you need a non contact ground wire tester?
That said, as mentioned, non-contact testers are good for what they are good for. You need a real meter for actual diagnoses. 60VAC neutral to ground and 120VAC black to ground.
Why does my ground wire keep getting hot?
That electrician did not do a good job because this means that the ground was open all this time. We just took over the lease, so who knows how many years it has been that way. On a side note, this 15a circuit I found to install the light on needs to be redone too.

What should I do if my electrical tester says its hot?
Get yourself a real tester and test from hot to neutral and hot to ground anywhere possible. Find the open neutral and you’ll find your problem. My real advice is to call an electrician. This would be the safest bet. Like @Petey said you need a different kind of tester, and one of those plug-in testers with the 3 lights is great for receptacles.

Why is a 60vac neutral to ground wire hot?
Dollars to doughnuts you are using a high impedance meter and the 60VAC Neutral to Ground is induced voltage (a.k.a. Ghost Voltage); very common. Connect some type of load (120VAC relay for exsmple) and induced voltage will disappear. Yes, they could lose their license, if they have/had one.
