Hi Frank,
I'm glad I can help - this board has helped me out many many times, so I'm glad to be able to do my part.
As far as the current stuff you're looking at, it sounds like your fuse was the problem for the instrument and wipers.
For the fuel level sender, I'm going to go out on a bit of a speculative limb - I'm pretty sure that the sender is set up the same as most and that the current that flows is larger when the tank is full - extrapolating from this, it sounds like you've got a short in the white (tan with age I am guessing) wire, so it reads full because there's no (or nearly no) resistance to the flow of the current.
So I guess I would check two things: check the connector on the tan wire (which probably was white originally) and make sure that it's not grounding to the frame somehow - this wire supplies the voltage to the sender, and then the sender grounds through the black wire. If the connector on the white wire isn't obviously touching anything else, then do the following check to see if there's a break in the insulation:
1 - Disconnect the battery
2 - do a continuity check with one test lead on the connector at the end of the white wire, and the other lead grounding to the body or the negative post on the battery - check several different ground-to-body points just to make sure your reading is correct
3 - if you get any continuity between that white wire and ground with both the battery and the wire disconnected, that would indicate a probable break in the insulation on that wire somewhere along its length.
For the issue with the fans, check the connections at fuse socket 6 - there should be one red and one blue wire on the "downstream" side of the fuse, and the red one trips the relay for the radiator fan and the blue one is the power for the ventilation fan - check the fuse itself for dirty connectors.
If your ventilation fan works, but your radiator fan doesn't (even after cleaning the connectors at socket 6), then check the fatter yellow wire that comes off the downstream side of socket 7.
If none of this works, let me know and I'll see if I can think of anything else - also, just FYI, the brown wire at the fuel sender is the "low fuel" light, and not continuous with the brown wire that comes off of fuse socket 4 - just the same color.
Please let me know what you find.
regards,
Rowan
