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.

Hi Edy,
I'm using this BGB schematic: http://bgbonline.celicatech.com/94_6gmanua...0four%20cyl.pdf It's for a 1994, but I'm guessing it applies to my '97. Fan relay no. 1 is supposed to have continuity across the pins shown on page 3, without power. With power, pins 30 and 87 loose continuity. The relay I'm pulling is the green topped one closest to the driver, on the outboard side of the engine compartment fuse panel. I thought about putting a paperclip in the slots for 30 and 87 to see if that would shut the fans off when the engine is cold, but I'm not that desperate or crazy yet. Edit: according to the BGB above, the engine main relay is supposed to be tested as well. This post has been edited by FrankB2: Sep 14, 2013 - 12:57 PM |
