More information:

75 2.0 - just started driving it to work daily last few weeks, has been running perfect.

yesterday on the way home i got caught in a major downpour but other than a few drips at the window, stayed fairly dry - not a drop in the trunks, engine area dry as well,- but i did try to use the fresh air fan that other than the low speed does not seem to really work at all, even at low, its hard to get it to go, so

- the alternater red lite comes on, tach goes to zero, and volt meter is on not reading anything. - checked all connections to the coil etc , fine, and no fuses popped.
- this is the weird thing, when i slid the fresh air fan controller over to off position the tach jumped back up-kind of, but not fully as i reved the motor it jumped up, but on idle dropped again, i didnt think they were supposed to be on the same circuit, but they must be. -lights all turn on fine, car runs idling fine, - so i dont think its the alternator or coil- has to be some kind of short at the fresh air fan?

anybody else ever have something like this before? one time i remember that fuse blowing, did not ever figure out why, but i just put the new fuse in and everyting went back to normal, but now that was like a year ago, and it leaves me wondering, did i turn that fan on at that time, blow the fuse? i really never use that fan since it doesnt really work anyway, but i was desparate for some air flow with it being 90 degrees, and raining.

i'm going to take a closer look at lunch time, hoping i can figure it out because i have to driving it tonight about 30 miles to a meeting then home 45. i dont want to be stranded on theside of the road somewhere with some wierd electrical issue.
