Have you done a voltage drop yet? If you already know this then feel free to ignore Find the ground for these switches and put one lead on the battery ground and one at whatever point these are grounded. Meter should read zero or close to it. If it is higher than .5 V (rule of thumb) than your problem is in the ground termination. If it is zero, than do the same thing but from the ground side of the switch to the ground termination. Repeat on the positive side as well. If you suspect the switch is corroded as you say, than a voltage drop across the switch with the switch closed will tell you for sure. A non corroded switch should have zero voltage (potential difference) across the switch when it is closed, and ~12 when it is open.

Awesome thanks!

Hello all! I bought a Brat a couple years back and she has been really good to me, except one of the previous owners installed an aftermarket turbo with a sidedraft Carter YH carb off an old corvair (it was a pretty cool setup). I however, live in California, and am trying to get it to pass smog. I am bringing it back to stock, and have it running with the Carter-Weber. The line marked in the first picture was originally running as a feed line for the turbo. I am planning on removing it and just installing a plug, but I am not sure what the stock condition was. The factory service manual is not immediately clear, Picture 3 shows a pressure switch installed on the non-GL models. However, Picture 4 seems to imply that the pressure switch is installed where the relief valve plug would be located (the line is coming from the block though and the relief valve plug is on the oil pump housing cover). My best guess is that on the GL models with the pressure gauge instead of switch, this port is plugged. TLDR: Can someone with a EA 81,1800cc, GL model; Send me a picture to see if that is plugged or if there is an oil line there that feeds elsewhere? Thanks!
