the HL good, means
the main power in the fender box was good, (not necessarily the FI there)
it also means that power made it to the Ignition switch.
that is why wiggling the key , finds a bad Ign switch. here.
the Ign. switch is complex in that it power 3 main feeds in the, not only EFI.
finding bad feeds is always hard on cars. they make them hard to diagnose. I hate cutting wires to make T-Junction, ever time there is a failure.
that leaves only 2 choices, back probing , a live failure or the sneaky wire , using tiny wire , inserted at any connector pin of choice.
in the factory or shop that have breakout boxes (an intermediary connector that allows testing) not sold .
watch out for relay reversals on the heater box. the pink wire is pump and blu-red relay is MAIN.
bug 2 comments.
more to come , will send , the Ignition switch page next.
my comments are all for bug 1 ,post 29 and not bug 2 , start line dead (clutch switch)
all speedo lamps dead but, not parking lamps (2 dim bulbs in speedo work )
the main relay red-black wire (FI) is hot at all times. not going thru, key switch.
the main distrabution , shows, the ignition switch feeds blue-black to 3 fuses, wiper, turnback and IG coil. if the wipers and turn sigs work then the wire is hot here.
when the idiot lamps in the head go dead this means,(only them not wiper and turns) that means the IG-coil line is dead. the is black-white. and runs all speedo lamps , except (park dim)
that leaves the IG-COIL feed or loss of Blk-white power, this loss kills main relay dead, so the FI is not even used, with Blk-white dead.
i read all my huge section on 96 schematics, ill compress it and send it later.
the key switch was suspected, but is not that if wipers work and turn/backup.
that leaves only those connections exiting IG-coil fuse., black-white.
for sure , all that counts , runs off this wire, including MAIN. relay.
if pull glove box. and monitor this color wire there. this wire is failing , not main relay, because the dash lamps fail, main can not work at all.
a new IG-coil fuse, may be it has a hair line crack inside. it.
