Test Sequence for Main Relay Circuit???

Hi All,

I'm really in need of some help. My 92 civic dx keeps having main relay issues. Even with the several new main relays. I tested the relay and it s working however I think I have an issue with the harness that plugs into the relay.

I'm looking for a test sequence similar to the one in this thread, BUT FOR A 92-95 Civic, which has a different main relay.

If anyone has this testing sequence and can post it up...it would be much appreciated.

This problem is driving me bananas. Yes i have a multimeter, and yes I knkw how to use it.

Thanks!!!!

With the key in ON(II), you should measure battery voltage (~12V) at all four fuel injector connectors. The low measurement of 0.5V tells you to troubleshoot the main relay circuit. Here are the diagrams to guide you:
