Usually a short to ground will cause a slight magnetic field. To find this and avoid expensive repairs use a compass to locate the short.
If a megger test fails you have a short between the two wires or the wire to ground that you are testing. This short circuit has to be repaired before the equipment is placed back into service.
There is an overload or short to ground in the circuit.There is an overload or short to ground in the circuit.

Not just the biggest test ground, but the biggest cricket ground; the Kennington Oval.

Testing for 12V DC power using a 12V DC test light, clip the test lead to a known ground (preferably battery negative post) then probe with the test light tip for power. Test light will illuminate when power is touched.Testing for 12V DC ground, clip the test lead to the positive post on the battery then probe with the test light for grounds. Test light will illuminate when a ground is touched.
Install a test lighb in place of the fuse--it there is current flow (to ground) light will illuminate Disconnect each light and/or socket until test light goes out--that will determine where "short" is then you can determine how to fix
After a short period you can take another test in 2 weeks.
There is either a short to ground or an over current condition in the circuit.There is either a short to ground or an over current condition in the circuit.
No
If there is an electric short, the resistance of the circuit would be zero. So you can use an ohm meter to test it.
