How to Troubleshoot an LC200 GTO Wire Splice

GTO cables are specially designed wires for the neon sign industry. They are built to handle the necessary high voltages and the outdoor environment. When connecting these wires, a high voltage connector, such as the LC200, must be used because of the electricity traveling through them. Troubleshooting an LC200 is the same as any wire splice. You need to determine if the electricity is making it past the connection.

Non-contact voltage detector

Instructions

- 1
  Pull apart the two wires going to the LC200 connector. They need to be separated to test the wires for power.
- 2
  Turn on the neon light so power should be going through the connection.
- 3
  Touch the non-contact voltage detector to the source side wire's insulation. If the detector illuminates, or make an audible sound, there is power going into the splice.
- 4
  Touch the non-contact voltage detector to the device side wire's insulation. If the detector does not illuminate, or make an audible sound, there is no power making it through the splice and it needs to be repaired. If it does detect power, the LC200 connection is not the source of the problem.
