Fuse Panel from the Depths of Hell that haunts my dreams

Everyday for two weeks ive been trying to get this working,
I removed the panel in a bid to remove unused unneeded wiring

Lots of different symptoms since trying to hook it back up
Now i am only looking to be able to start the car and run it so i can drive it safely to an Auto electrician and get them to do the lot

I took photos lots of them before and i labelled every wire

At the moment when i even connect the battery the starter runs and sparks fly.

If any elec gurus please give opinion looking at these wires what do i need to change
to

1 start the car
2 run the car

without melting anything

I don't care about headlights or heaters or any wiring that is not neccessary in the actual driving

I know i must be close because this morning when i connected power the ignition lights came straight on i dont know what ive changed, i took photos of all of it but then i cleaned the wires and now with my eyes they all look the same to me

I just need to be able to drive it Asap to an Auto elctrician


I hope someone can make sense of it, if you cant at lease offer opinion on something to try?

Theres a Blue wire off the fuel relays thought it went osmewhere but theres another blue there now..
plus ive got about 5 red wires i know they go near the start of the fp if i dont need to hook them up to drive ill let the auto elec do it.
I took out the 3rd relay in my quest to get it running i dont think its needed for driving.

I cant see if the Multimeter is on or not it doesnt beep it never has, waste of ten dollars


This is getting close to causing divorce with the late nights

there must be only 3 or 4 wires i need to hook up correctly to drive it?






I did the right thing before but then i cleaned the wires

Heres update, pls see pic,

The Yellow wire was causing the short i obviously had it in the wrong plac,
i mocved it over to the bottom side of number 14 fuse, (8 from the right)

ignition lights are on when i connect the battery so i guess i need to find ignition leads and locate correctly,or are they correct?

heres pic of current setup i will post more pics as i make the changes

That's quite the nightmare ya got there.

I have an easy suggestion fer ya; run independent hots to fuel pump, ignition, and whatever other CIS needs straight from the battery, and let someone else tackle that beast!

Voila...

Yes thats my Plan

But can you tell me which the ignition is?

the Fuel pump relays are already individually wired but there is a blue wire off them that i dont know where to put>

It would be nice if you could find someone with the same year 930 you have and then look at theirs and take pictures and stuff to try and figure it out if they let you. I don't know, I guess maybe there aren't many of them where you live.
Good luck with it. It looks like you're off to a good start with labeling wires.

One of the things I hate about working on that fuse box is you're bent over the fender looking at it upside down and after a while it just drives me nuts. Wiring is not fun unless you make it all look nice and neat and it works afterward.

take the gas tank out and sit there while you rewire it

I wont do that for the sake of one misplaced wire no matter how comfortable that will be

Ive got it all sorted now except that when i connect power ignition is (always on) and the fuel pumps wont run when turning key but when i bridge 30 and 97 they will run as soon as i connect power, ?

so im sure it is just one wire (ignition) in the wrong place

21 fuses over 42 wires (42 x 21x21x21 etc squared) mmm i think i better buy a lottery ticket while im doing this

Was there any fuse "jumper bars" that you may have removed and forget to put back?

Hi not that im aware of, but will check that next, At least im no longer shorting fuses when i connect battery so the flow is correct but the switching power has me confused, I think its the Blue and or the Yellow wire that need to be located in the right positions.

cant get my head around this, ive read books, pics easier but don't have for months im on this, keep going back to it, I drove it last week got lucky but don't know what I did,, was hard as the Duct tape holding roof on wasn't sticking well so I had to hold it down with my hand while driving it.. anyway that's another story...
I am looking for things like red wire with white stripes go to number 6, that sort of thing, or some photos or anything that could help me start my car, its been a while and I need to drive it, soon..... im getting withdrawals

Ive stripped out relays leaving fuel pump relays to help me start,
I have gotten them working at least but ignition is hit and miss, I don't want to send the wrong power to the wrong place

see circled,

Theres 4 black wires one with plug on end, wtf?
If the black ones don't need to run car ill worry about them later,

I only want to turn key to each stage and have correct sequence of events happen in each key stop is all I want to achieve this month and ill be happy.

also in casing theres thich Red with white stripe in tubing with Black wire and also thick green wire with plug

If anyone could offer advice on at least one of these? I could get closer to finishing?
MR Fairman, Billjam, Ronnie anyone???

NO Laughing or Jeering

this is a serious matter!!
No stupid pics of non related stuff unless its porn ,

Ps note the blue sqauares to highlight the thick one in casing with three wires coming out...black, red with white stripe, and a thick green with socket?





Theres this really thick red wire its always live im guessing first fuse location cos its the biggest?

I don't think there is any specific fuses for ignition or starter in there.

Has the car got an alarm in it?

This picture is of my 76 ROW 930.

Do you have your fuse box cover with the details on the back?

Word of warning though I found my fuel pump wiring to be somewhat different to every wiring diagram I could find.

Excellent thanks,
Yes my car has an alarm it is part of problem im sure also.
I just went to start my car earlier by bridging it all and going strsight to the starter motor to give her a kick, I think I need to check the groundings as even with full charge to starter it is turning over very slowly,
Anyway thanks for pic ill see what I can get out of it tomoz.

Rob

Boy do I ever sympathize with you. My car had an 80's alarm from hell installed that had to be surgically removed. It was like a parasite with tendrils encasing the nervous system. What a nightmare.

Your alarm will have 1 or 2 kill circuits. If they have made the cuts around the fuse box you should be able to tell as a pair of wires will go back to the alarm box. Maybe even an external relay attached to the alarm.

They cut one or more of the fuel, starter or ignition. Generally these cuts are done under the dash. But in a 911 the fuel pump wiring is accessible and identifiable at the fuse box. So hunt around for an obvious cut connected to after market wiring.

Can you determine the voltage at the battery when cranking? Can you verify the sluggish cranking with another battery?

Take no notice of the fuse allocations in my picture. I am going to get all new fuses. I chucked these in as I was testing after a clean up.
