Sorry to double post--first time here.


1986 Ranger with 2.9 V-6, manual trans.


Fusible link going to a relay near the computer has burnt up. A yellow wire The fusible link) goes to the relay. A yellow wire goes in and out, along with a red wire, and what looks like a yellow wire with a blue tracer. THIS wire is heating up when I attempt to start the engine (which does run, but barely).


I assume there's a short somewhere causing all this, but I don't know where to look (or for what this relay is for). The Haynes manual had been of no help.


Any help would be really appreciated! I love my little truck.

There are 2 maybe 3 relays on the inner fender in 1986 Ranger engine bay

Brown base Relay is EEC relay(computer power relay)
Green Base Relay is Fuel Pump relay
Black base relay is Air Conditioning cut off relay(optional)

Yellow wire is most likely on the EEC Relay, its the main power in from Battery(fusible link)
Red wire on this relay feeds power to computer(EEC), IAC valve, Fuel injectors, Fuel Pump relay(not fuel pump), spark system, and transmission

 

Right you are, and thanks.


I solved the problem--it was a bad high pressure FP. It was drawing so many amps it fried the fusible link.


And I was off on the colors of the wires: it's tan, yellow, red and orange with a blue tracer.

PS: Thought it may have been a short in the inertia switch, but it was not wire dup! It was there, but the factory apparently never wired it up.
