My long build of a 1940 56S

Recommended Posts

I took a break yesterday and went through the last box of stuff from the shop that did some work on my car. I found more parts for the wiring harness (I thought I was close to being finished), including the fuse assembly for the cigar lighter (see illustration from shop manual and part). Bob's shows this part in the catalog, but when I called him he stated, "sell when I get 'em, but don't have 'em now and nobody makes 'em".I called before I found this part and have no idea where it came from. Now I need to find the bayonet terminal. Called YnZ customer service yesterday and they are very knowledgeable and willing to spend as much time with you as you need to answer any questions. I also spoke to the customer rep about the wiring from the instrument light switch to the instrument lights being very short. He said that he would make a note in their files to make this a couple inches longer. There is a bulb right above the steering column that snaps into the speedometer housing and this gave me quite a fight. 

 

While I was taking a break from my frustration with the wiring harness, I showed the jack and lug wrench a bit of love. I sanded all with a 1000 grit sand paper then used a rattle can to hit it with two coats of gloss black and one coat of clear. I have enough material left from doing the trunk to make a small cloth case so they will not rattle around in the back of the car. 

 

I will declare this a study day, to see what loose ends are needed to finish up the wiring, also a garage cleanup day.

After my study day, I worked on the instrument switch and light switch. If I had worked on this from the start (seven years ago). This would have been much easier, as the wiring was all numbered real well and everything matched with the wiring diagram in the Buick manual plus the hand drawn diagrams really helped. The problem came in when the numbers were removed from the wires, or were worn to a point where they could no longer be read. At times a wire would exit a loom without a number and I used a wire tracer to tone it out to locate the other end of the wire. At other times I used a wiggy to test for continuity (such as the #12 wire that exited the loom in the trunk next to the tail light). 

 

The instrument has six connections and two fuses. I thought it would be a good idea to make notes stating what the wire colors were and where they were going, as some of the numbers were missing.  Two connections come from the light switch, one to each end of the fuse. One connection goes to the dash lights and one to the map light above the ignition switch. Two wires go the the clock and light for the clock with a split for the switch that operated the glove box light ( still working on what the switch looks like and how to mount it. Any suggestions). Another wire goes to the light for the ash tray. I would love to do three or four more of these to get more comfortable with this (just kidding). Working as a volunteer at the hospital today, so I will be back on this tomorrow.

Today I decided to put on the glove box door and to install the glove box. I really thought that I was going to have an easy day, well I was wrong again. I started by putting the glove box in first, that seemed logical. I carefully put the u clips on the box taping the material with masking tape so when I put the clips on it wouldn't shred the cloth liner. The right side of the box went smoothly, but the left side took some massaging to get everything tucked in right. Next I tried to put the door on, you can't make any adjustments to the hinges once the glove box is in. So, take the door off, pull the box out and start over. Put the door on and line everything up (make sure it closes and latches). This was a bit of a challenge, but most of the car has been. I tried using the bumpers that I bought at Bob's, but the door would not latch even after several adjustment to the latch. Now put the glove box in and fasten all trim screws. Small hole on the left side of the box is just large enough to bring the braided loom for the clock and the light for the glove compartment. Tomorrow I will wire the clock and connect the wires on the other end to the instrument switch. When I work on the clock, I will refer the the third image below.

It appears from the diagram that the wires exit the liner on the left like the picture I shared from my car.  But then it looks like a clip holds the wires to the left side of the glove box door.  Do you have that clip?  I'd like to see a photo of it.

Hello Ken,

 

Thanks for the information, I do not have this clip. It appears as thought it is part of the the wiring harness that connects to the instrument switch on one end and the clock on the other. My original thought was that this clip attaches to the glove box door hinge on the left hand side. It appears as though this not only makes the installation neater, but also serves as a ground. I very well may be looking for an aftermarket clip that at least finishes off the install. There is a ground wire that attaches to the clock.

I was studying Gary W's post on finishing off his clock and lamp install on his glove box and it gave me some ideas and more questions. If you go to his post "37 model 48 restoration on page 26 he describes the mechanism for making the light come on when the glove box is open. I am a bit confused by this, it seems as though it is part of the lamp, I have to read this again and maybe it will sink in.

It was a good day, the left side of the steering column is complete and all wiring is done. On the right side the enclosure for the ignition switch, light switch and choke was installed and the dash should be finished off. The two screws that secure engine turned portion to the dash were quite a challenge, one hand behind the dash and completely by feel alone. I still have to put the light in the  glove box and the light for the clock. When I get the proper light sockets for this hopefully I will have a solution for the switch that makes the light come on when the glove box door is opened. 

 

The picture to the far right is of the seat brackets. I put them in some Evap-o-Rust over night and gave them a wire wheel treatment. Then I gave them a coat of primer and will add a coat of gloss black tomorrow. 

 

Looking ahead, after the dash is complete, I will give the floor the same treatment that I did in the trunk with a coat of primer and a coat of gloss black.
