Butcher Mechanics on electric wirings

[vizail]

Hi Guys
First of all my gratitude to J.Walker, Gunter and Jim with his rennnlist CIS page. I have alot of work in my Car and all the help will be apreciated. This pix will help understand my nightmare.
Back in Oct 2004 ,I posted a topic on Frequency Valve. After having a small "Stroke" that send me to the hospital for quite some time I retake the RESTO work with my 911.
The search keep's on and on and I hope that this information can be an advice for Porsche and almost every car owner. "Search for a good Qualified & Certified, Mechanic", and be willing to sue your Mechanish or shop.
The Pix will say more than words..!
The Fuel Pump Relay Cables were cut clean from the relay socket harness.

Then a VW 4 terminal relay was Jumped and Instaled Intead of the proper 901-612-333-00

Here is the sucker

Then I replaced the 3 fuse carrier 911 612 093 03 , notice that # 18 fuse is burned and that happened because there is a short in the Total Interior Ligths circuit.


The # 18 fuse burned as soon as I found that the red/white wire was cut .That wire comes from the FP rellay to the WUR and then to the OXS rellay. I re-connect and the OXS rellay is now Clicking, but the # 18 fuse burn.

I keep on searching my 911 wiring and I still find so many discrepancies ..take a look at this fuse wirings

Take a look at this FP clipped cables

Talking about strange conections and wires ,I found this useless wire that runs from a live "fused" to one of the ventilation hoses


Hope for good imput.

Any chance of tracking down the factory wire harness from a wrecking yard or donor vehicle and installing those? The wiring diagrams are pretty helpful. I bet you'd be better off installing new harnesses rather than cleaning up that mess. I am doing some similar cleanup of my own, but my wires are factory and not such a disaster.

Good luck,
Doug

Vic,

There comes a time (and I think that you are well past that time) that its better to find a salvage car and get a good wiring harness to transplant into your car.

I have done this several times just "harvesting" wiring harness's out of wrecked cars for spare wires and pieces. Its best to do it yourself, as the yard monkeys that sometimes work in salvage yards do not care and just rip and pull the harness out. If you do it slowly and carefully you can end up with a complete harness and it might be easier than trying to patch up the mess that the PO left you with!

For smaller patching job. Eagle Day sells original style German wires. I was feeling pretty good the other day to find I had some new wire "in stock" to duplicate the damaged blue-with-green-stripe wire for the temp sensor on a motor I'm working on. It's very satifying to be able to do the job "right". www.eagleday.com

And Then I found the rout of the misteroius cable
And then there was a useless fuse carrier hiding inside the ventilation Hose


I cut the unnesesary wire and reconnect

Now take a look at this A/C replacement rellay...! A masters work

And the wiring with a melted(not burned fuse) Great

Live from the Battery to the A/C rellay .. a fire hasard.!


As I said before, be very carefull when selecting a mechanic for your Porsche. After working on Aircrafts for so many years, I take this 911 RESTO as a great Challenge . I don't have to do it myself, but I've lost my confidence in the so call local experts and even the local Porsche Certified Mechanics, from Garage Gomes in San Juan. Even one has more information when ordering a Part or discusing a problem with one of the so called Cert. Mech,s.
In short I rather have your comments and advice and they are very Welcome..!

I still have to get curren to my FV, and checking the continuity from the conector T12 (#1 Male/Pin) & (#2 Male/Pin) to the FV connector I get continuity from one side of the FV Connector in both #1 & #2 Male Pins..!

At least the guy used electrical tape to wrap the, ah "nodules" in -- it _could_ have been wrapped in masking tape...

[FrayAdjacent911]

Some of my wiring is pretty boogered up. The headlights were wired weird, probably because at one point, there were foglights, but they were deleted. I still have the mounts, but no lights.

The fuse blocks are intact, but pretty dirty, so I may take them out and clean them up. There was a relay with a socket and some cut wires hanging off of it laying in the boot... I suspect maybe it was used for the fog lights? Anyway, I'm going to save the socket and relay in case I need them (say, for an H4 headlight upgrade?)

I'm gonna try to get pictures to document it all.

This is all in stark contrast to the beautiful ATO style fuse update done by Fred Cook ( more threads like this...) --->

Fuse panel upgrade to ATO type

Ok now ..!

The cables travel from the Battery to the fusebox, then from the fusebox ..some go the the Gages and switches and some go trough a gromet right under the fuel filler rubber connector trough the tunnel.
Right or wrong..?

Vic,

I had a friend/customer who drove his 930 from Guatemala City to Denver in about ’77. Somewhere in rural Mexico there was a melted wiring harness behind the instruments. The entire repair was done in situ with all yellow wire. It drove to Denver and everything worked perfectly. He decided to leave it alone and I think still owns the car today.

Of course he also flew his (smallish) helicopter from Guatemala City to Denver and survived. He is a German car collector par excellance. He has an executive MB touring car from about 1941 from you-know-who and many others including F1.

Best,
Grady

I'm not Mexican, I've been to Mexico City and other sites like Acapulco, and Merida.
I admire the Mexican inginuity and talented mechanics .
When I visit a country I like to get toguether with working class people ,among them mechanics. In this case Mexicans really know their thing. They rebuilt and re-rebuilt the cars and buses over and over again because is very expensive to buy newones.The same goes to the rest of Latin America ,it's strange to see automatic transmisions. They even re-built their brake calipers,cilinders ,brake pumps etc. etc.
Back in the States and PR they don't even like to sell the repair kit's, they like to sell you the China-rebuilt Part.
Many times people don't take the time to really re-built a part.
"THE COMODITY OF CAPITALISM"

In regards to the yellow wiring and my car , I have to repair it properly because it has to be done the right way.
Thank's to God and other friend's that I have the Bentleys and set of copies of the original Factory Wiring Diagrams , this will be a great help in my Porsche RESTO.

Thanks for the Reply

Don't take me wrong.. I have nothing against Mexicans..!

Vic

[Grady Clay]

I hope I wasn’t misinterpreted. That was praise for the Mexican ingenuity in some rural community where the 930 found itself in distress. If I had been there and the only wire available was a reel of yellow, I would have done the same thing. I appreciate ingenuity. It could have been the States, Canada, or some other place in the world. The 930 works and got to its destination.

Best,
Grady

In regards to Car wirirngs my destination is,in every direction as long as it's ahead and forward..
Is great that I can get pieces of the same wire from <www.eagleday.com> or <www.vehicle-wire.com.uk>

The wiring in my car was completely shot. Before I bought it it had a fire in the power windows. That was my first wiring repair on the car. I have since done all the wiring except for the wiring in the dash. that seems to be doing fine.
Go over the wiring diagrams and rewire the circuits one at a time. the wiring diagrams are fairly easy to read, and if you change a wire color then mark the change in the wiring diagram. that is what I have done. best of luck.

Grady,

Grew up in Mexico as a kid. 4 fun filled years in San Miguel.

Driving back to Texas one year our '61 Chevy blew a head gasket. No spares anywhere. Mexican shadetree mechanic told my Mother to come back in a few hours, that the car would be fixed. We did, car was ready and we continued our trip. We finally sold that car 5-6 years later with that repaired head gasket still in place and still working.

The mechanic had no parts to repair the engine, but he was re-doing his floor that week. He hand cut a head gasked out of linolium, bolted it on and away we went. Compression? Who knows how much it was down on the other side but it ran and ran well. Would have loved to see the look on whoever ever pulled that head off and tried to figure out what was going on!

They are a lot like the Cubans in that they make due with whatever they have at hand to keep the car going. Nothing wrong at all with yellow wire in my house as long as it gets you home. Wish you luck with the wiring! Been there done that with old Viscount airplanes... that was a nightmare, hope the 911 is easier!

When I was restoring my '70 big block Corvette years ago I found a similar mess in the engine compartment. Someone had cut every wire to the engine prior to removing it, re-installed the engine and re-connected every wire with what I affectionately refer to as a polish connection - copper twisted together and finished off with masking tape.
Needless to say I bought a new harness from my Chevy dealer.

[Diesel_mp5]

I had that problem on my 79-Sc. And I found the MAGIC tool to repair....

[Willem Fick]

This looks all to familiar. Didn't have so many wires cut, but someone had obviously rewired the fuseboxes without the use of a wiring diagram Took me forever to get sorted out, but gave me the opportunity to remove and re-wrap the harness, and then also to fit newer "blade" style fuseboxes.

[vizail]

All electric seems to be running weird in this 911. Just yesterday the starter began making a strange noise after starting. To late and dark to look and check now.
Will check tomorow. Strange thing do is that this rebuilt starter don't even has 200 miles on it.
