1986 Fusible Link Question - Fan Relay
On my 1986 Convertible 4+3 manual, I used the Factory Service Manual to trace down an inoperative cooling fan, and I've found out the there is no power to the red wire (Terminal "E") going into the fan control relay, so it looks like the fusible link is bad that is supplying power to the relay; I was able to get the fan to run when I installed a temporary fused wire directly from the battery to the red wire going into the relay; my question is what size/rating fusible link do I get to replace it? I couldn't find it anywhere in the manual; also, can I pick one up at Pep Boys, AutoZone, etc.?
Thanks, Chris

Manually spin the fan blade and verify the motor doesn't have a lot of resistance which could have caused the fusible link to blow.
If you look at the schematic you need to cut out the blown part of the fusible link and solder in a new piece. In the schematic the Link O is the one you say is blown. If you notice it says its .5 Color of the wire is Orange.
The .5 is the metric wire size. So at the auto part store ask for .5 mm or 20 AWG fusible link wire.
Notice where the arrow points in the schematic is a splice where there is another Red wire that goes to another fusible link. Make sure you don't damage that wire at the splice when you do the repair.

Great work on the troubleshooting. Much better than the innumerable "please help!" threads where the first sentence starts "So...." and contains seven "lol".
