As my headlight suddenly stopped working recently, (see two posts below) I spent the afternoon in the garage for troubleshooting. I got a very good troubleshooting guide from a fellow Cadillac enthusiast from the USA.
Glen wrote the following:
“If you take the panel under the steering column off I think you can reach up and disconnect the connector from the light switch. Or you maybe able to get a meter probe up there to check voltage. The battery connection to the switch for the headlights is on the 14 gauge yellow wire. This only supplies the headlights and front parking lights. If you have 12 volts there then your problem is in the switch. There is a circuit breaker in the switch and it may be bad or the contacts in the switch are bad. IIRC these switches have a vacuum switch on the side that operates the headlight doors. This makes them hard to find. They do not interchange with the 68 Eldorado because in 67 the parking lights only come on when the switch is pulled out to the first position while in 68 the parking lights come on with the headlights also. If you do not have voltage on the yellow wire then you should check the fusible link on the starter. It is an 18 gauge dark green wire that changes to a 14 gauge red with white tracer before it gets to the connector. Check for 12 volts at the connector and check the contacts in the connector. “

Glen was spot on with his diagnose and it turned out that the green 18 gauge fusible link was the culprit for my headlight problem as it came apart for unknown reasons.

the green wire once was a fusible link - it fell into pieces when I slightly pulled on it

As a follow-up Glen recommended the following:

“You might want to look closely at the break in the link. See if it is melted or did was it broken by mechanical means. If it was just pulled apart or cut then you have to check what caused that. To trouble shoot this if it was actually melted due to over current, I would unplug the headlights and front parking lights, and temporarily connect a headlight or other big light bulb, in place of the fusible link. You can then try things without blowing fuses. With the troubleshooting light in place it will light up brightly if there is a direct short. With the headlights and front parking lights disconnected the test light should not light up at all under any condition. You should be able to move change the position of the headlight switch, switch from high to low beam (light switch in the headlight position); wiggle the wire harness anywhere and not light up the test light. If it does you have found the short.”

I did this procedure today but it did not show any shorts. I then reconnected the front lights and everything did work again. I will now have to find a replacement fusible link which is very uncommon over here in Europe. I will replace it together with the positive battery cable where the clamp is almost falling apart. I hope the issue wont come back. It looks like the fusible link maybe only fell apart due to age as it did not show any signs of burning. Its located very close to the starter and the exhaust manifold - so maybe 42 years of dirt and heat just made it crumble into pieces....

When I drove the 67 Eldorado home from the shop last tuesday (see report below)- I stopped at the park deck of the local shopping mall to shoot a couple of quick pictures.
You can find them in the Eldorados gallery.

I took my 67 Eldorado to my restoration shop yesterday to have it checked for the Austrian registration.
When I arrived there the headlights did no longer work. They did not have any problem before.
When the inspector wanted to turn them on - the headlight doors did open but the lights did not come on.
Also the parking lights and high beams do no longer work. The taillights did come on though and the cornering lights and turn signal do work as well.
Very strange. Checking the fuse panel I found out that there is no fuse for the headlights. My guess is now that it must be the headlight switch - can this be repaired? The shop manual mentions a 25amp circuit breaker in the switch but it does not mention how to repair it or check it.

The other thing which stopped working yesterday was the Automatic Level Control. The vacuum operated compressor in the engine bay seems to work as I can hear a ticking noise, but the car does not raise. I also added some pressure (100psi) to the service valve at the compressor but the rear of the car did not raise at all. When I depressurized the compressor the car did not come down any further either. Very strange. I really need to get this fixed - non working parts are making me crazy!
The car lost the yellow plastic cap which is located on the top of the regulator valve while driving it into the shop. Unfortunately it landed directly below one of the tires and was crushed to tiny little pieces. I will have to try to find a replacement. I have no idea how this could have come loose.

The car did not pass the inspection for some other reasons as well , like a sticky front disc brake, worn ball joints and pitman arm and some other minor things . It will keep me busy repairing all this for a while. Whats worrying me most is the headlights and the ALC as I do not have any clue at all.
On the positive side - the car was a pleasure to drive the 60 miles to the shop - its so much different to the “regular” Cadillacs - Big, silent and powerful and no big boat ride ;-)

Today I once again tried to fix the low pedal issue on the 67 DeVille´s brakes. I recently replaced the booster and master cylinder and had a low pedal problem then. The brakes worked fine, but the pedal travel was way too long. I first suspected air in the lines, but we really thoroughly bleed the whole system multiple times. I then thought that the push rod of the new master cylinder might need some adjustment, until I found out that the Delco Moraine boosters are not adjustable, whereas - the also used - Bendix boosters had an adjustable rod.
As I replaced the complete front end including the entire front brakes last year, I did not think that the drum brakes might only need a simple re-adjustment. As it turned out the front brakes were out of the range where the star-wheel can adjust itself while driving the car backwards and applying the brakes.
I now adjusted the front brakes pretty tightly and the pedal is now pretty firm again. I hope it will stay like this. If not - there must be something wrong with the automatic self adjuster, but I´m very optimistic that the problem is now solved. I also gave the rear drums a check - they turned out pretty fine. I just wished the DeVille had front disc brakes like my 67 Eldorado...

While my wife and I were on holidays in Vorarlberg, we shot this music video for the local band “MAGUAMS”.
We shot this „no budget“-production on a rainy sunday morning in a storage facility - the cars in the background were the perfect backdrop for the band. The musicians are a great bunch of guys and we had lots of fun during the shoot. Our Buick Roadmaster also served as a background props for the shooting - thats why I´m posting this video on my website.

While my friend Tayfun was in town to help me with my Cadillacs, it was time to exchange the still original brake booster and master cylinder of my 1967 Cadillac DeVille.
Everything went pretty smoothly at first - only bleeding the brakes was a little complicated and it did not help either that I spilled some brake fluid into the engine bay. Some harm was done to the black paint which had to be repainted immediately. So it took us some unplanned time to get everything back in working order. As it was raining heavily we could not even test the brakes. In the meantime I did a test drive and found out that the pedal travel is way too long. Looks like the push rod in the booster needs adjustment... D*mn this means removing the master cylinder once again... I hope I will find the time to do this soon.

My buddy Tayfun came to visit me for three days to help me with detailing my 1967 Eldorado and to exchange the brake booster and master cylinder of my 67 DeVille.
The Eldorado got a wet cleaning treatment of the carpet and trunk and a full detailing of the interior - which looks like from a new car now. We also started to clean and polish the original paint but ran out of time. We only finished the hood - but the before and after difference is amazing. More work will be done soon.

...they turned out as if they just left the factory - awesome - this Meguiars rubber treatment is more than fantastic!

Tayfun - wet cleaning the carpet and trunk - looks like new now as well - the low miles are showing on the interior pretty well

The hood´s paint came out really fine and smooth - unfortunately we ran out of time and could not finish the rest of the paint

My 1967 Eldorado originally came with an AM radio only, which is basically useless in todays world. The seller of the car put an FM/AM unit in the trunk which he had for the car but never installed it.
Today my wife helped me trying to replace it. It is always a pain to get the old radios out, as the electrical connectors are pretty hard to reach if you have big hands like me... After some fiddling and lots of bad cursing, the radio eventually came out. During this procedure I found out that somebody messed around with the speaker cables which go to the rear speakers and installed new ones - which were connected directly to the front speaker. They cut the wire going to the front speakers and spliced in the rear speakers. Not very well done...

When I finally managed to install the “new” AM/FM radio I found out that it does not fit at all... It either comes from a 66 or a 69 Cadillac?

So I installed the old AM radio coming from my convertible where I did the same procedure 2 years ago - only to find out that non of the 2 speakers seem to work anyways...
I now have to find a good used 1967 AM/FM radio and 2 speakers - the list of things I need is getting longer everyday. I will also have to repair the wiring of the rear speaker back to original.
Thanks to my wife Afra for helping me!

The US-CAR-SHOW in Dornbirn is held every second year and is Austrias finest car show.
I always exhibited one of my Cadillacs at the indoor show in the past years, but this year I decided to take the Roadmaster for the trip and just take part as a regular visitor.
The show itself is a class of its own. You can find hundreds of Hotrods, Classics and Muscle Cars there which you do not see at any other shows in Austria. We really had a great time there and are looking forward to the next edition of the show in 2011.

I shot 2 hours of footage at the 2 days of the show, which my wife Afra and I edited down to a 11 minute film, which is now available on my website.
It features some great Cadillacs like a 53 Eldorado, 57 Biarritz or a 1959 Biarritz and many other great cars.
The film is pretty big as the quality is very high - so be patient while downloading. It was shot in Full-HD in cinemascope.
You need the Quicktime player to be able to watch it - if you do not already have it you can get it for free at Apples website.
