Well, I got to drive my 320i for about a day after replacing the headgasket :rolleyes: . This afternoon after getting back from Sac. I went inside grabed a soda and watched a little tv. Went back out side to wash my 320i and noticed the fan was still on, I did an eletric fan conversion. So I put the key in to see what the temp was, and it showed just under 1/4 so the fan should be off. So I pull out the realy and the fan turns off, as expected, put the relay back in fan comes back on. I take the relay back out and take the cover off, noting looks burnt or broken. So I plug the relay back in and now the fan doesn't come on, so I thought I fixed it. So to test it I flip my over ride switch on which will make the fan come on whenever the key is on, but the fan doesn't come on :mad: Now I break out the test light and make sure I have my 2 powers comming into the relay holder and I do. So tomorrow instead of setting the A/F ratio I have to track down a new relay and hope that fixes my fan issue:rolleyes: So hopefully Tuesday the fan will be fixed and my A/F ratio set.
