I'm in the process of chasing down a cooling fan issue. The cooling fans stay on continuously anytime the ignition key is on (just started doing this). I was checking the cooling fan relay just to see if its contacts might be welded closed when I noticed an alteration of the fan fail relay done by the previous owner (PO). It looks to me like the PO pulled the fan fail relay and put individual inline fuses to connect to each fan. I'm guessing this eliminates my fan fail feature but perhaps the PO felt that the individual fusing was a good trade-off. Any concerns with this?
By the way, the cooling fan relay is just fine. I'll be checking the otterstat next. I suspect it may be stuck on.
Oh, while I'm here... I also noticed the fuse #7 looks like it may have gotten hot (see close-up of fuse panel). Kind of surprised since this fuse is listed in the owners manual as Lambda control unit and fuel pump. I wouldn't expect excessive current. Is it common for this fuse to get hot?
My final peeve is with the wiring schematic. Many of the relays are shown as blocks and you can't actually see their coil circuit and contacts. The operation of the fuel pump is an example where it's hard to tell how power gets thru the RPM relay to the fuel pump. On the other hand, I'm more than pleased that we have a seemingly very complete electrical schematic as a reference.
Thanks,
Ron
