Title: CHAUVIN ARNOUX CA 6411 Ground Tester - Repair
Post by: 2X on September 28, 2024, 07:01:06 pm

Hello,
I have the “CHAUVIN ARNOUX CA 6411 Ground Tester” and when the jaws are closed it shows that are opened and also when jaws are closed, I am hearing a noise tic tic… like a relay open and closes periodically. Ι can’t open the jaws to see what is inside… does anyone open these jaws?

Also, I made a schematic from the PCB that the connectors of the Jaws are connected but I didn’t find something and I replace all the chips with brand new except from these two (same) in the yellow circles where I can’t find a datasheet (Image 5). Any ideas for troubleshooting?
