Bought these a few months back and finally came around to using it. When plugged in I had fuel shoot out all over the place. Made sure relay was switched to off and it was. Checked for continuity on ALL relays with the switch to the off position, there is still continuity. Be careful when using these to test thinking the on/off switch works. The on/off switch does not work and there is a constant connection. All relays work as a direct jumper.

These circuit testers are built well and fit in the appropriate relay sockets correctly. However, the current testing loop is wired wrong. With the loop intact, the switch doesn't do anything because the loop itself is providing a path for current to flow. With the loop cut, the switch works properly.

These are easy to use and cut down on the tracing time. Diagnosing electrical issues can be very tedious and time consuming. These switches are well made. They do a great job helping to narrow down the issues. I definitely recommend.
