Okay.... I recently tested a relay for continuity, and two terminals caused my meter to beep, and the other two terminals caused my meter to read .064 without beeping. I came across a car forum question, in which the poster was using a 4 pin toyota relay on his hot rod, and was testing continuity. This was the same normally closed relay I was testing, and he got the same results. One person said the .064 was continuity for Toyota relays. I'm not an electronics wizard, so if anyone has any knowledge here, that'd be great. I broke a relay case yesterday tugging it out, and picked up a new relay this morning. It's supposed to have continuity across two pins and no continuity across the other two (fan relay no. 2) without power. Both the new and old relay read .061 ohms across the pins that are supposed to have continuity, so I'm guessing that's continuity without the beep.

 1997 GT Convertible diagram. 3 switches that feed ground to the various relays, it's a somewhat complicated system at first glance but once you trace it all down and look at it as a BASIC AND/OR sort of operation it's not so bad. -------------------- |
