Hi all,
I'm trying to revive an 86 GTV6 that has been sitting quite a while. So far we've cleaned all of the various ground and sensor connections and the motor spins over fine. Cleaned all of the fuses in the fuse block.
We cannot get power to the green/black wire to the coil nor can we get power to the fuel pump. I can hear (1) relay under the dash and one on the pass side fender well clicking on when I turn the key to on position. When the key is turned on there is power to the green/black wire at the main fuse box but not at the coil. We've even tried to replace the computer with another one of the same number but no go.
Any suggestions on what to ckech next? thanks.
jtferris what I would suggest you do is remove the bottom plastic cover on the steering column (the screws holding this together are hex-head) and follow the wires from the ignition switch to the 3 pole connector further down the column.Closely inspect the connections in this connector.I have seen them overheat and oxidize.If you look at the attached wiring schematic you'll see the green wire that I've highlighted runs from the ignition switch to a coil ballast resistor.From the ballast to the coil the wire is green/black.I have no idea what year GTV6 this diagram is from but on my 86 GTV6,Alfa no longer used an external ballast resistor but instead the wire which is green/black on my car goes directly to the coil + and should show 12+ with the ignition on.
13 = ignition switch
14 = connector
6 = ballast resistor
7 = coil
5 = ignition module (attached to the coil chassis)
