1936 wires cut/ where they go ??

[Oldog3]

I have a running motor from a 1936 car , when the motor was pulled these wires were cut , I would like help identifying them and where they go before I reinstall in my 1941 truck

The first picture shows the wire as they come out of the left hand metal wire loom ..

The next picture shows the wires the color I believe they are ...wires 1 and 5 are heaver gauge and "Y" in some wires means yellow

I have a copy of 1928-48 Ford Chassis Parts Manual and I still am having problems with the schematic and routing of these wires
Thank you
Dan

Ok, not sure you have the wire colors ID correctly, but close. Here is what they should be per the wiring diagram:

Yellow/Black - to the cut-out on the generator
Red - to the ignition coil
Yellow/Red - to the light control switch
Black/Yellow - to the oil pressure sending unit on the engine
Blue/Black (or Black/Blue) - from lighting switch back to instrument lights.
Yellow - power from the battery at the starter solenoid (this one goes through the amp meter)

Thank you JS....... I am going to take this info to the schematic and see if I can figure out how to get this motor running again ..any other hints along those lines... I did not get the coil and will search what the cut out on the generator does
Thanks Dan

If you need a copy of the '36 wiring, I have the diagram and can scan it for you. It isn't unusual for someone who is removing an engine for salvage to cut wires and all else that run between the engine and the vehicle. Fortunately, the early cars are fairly simple. Modern cars are a nightmare!

If you are asking what the cut-out does, it is an early version of a regulator. If you are familiar with the rectangle boxes on later cars with generator (and some alternators) with the three connections, the cut-out serves the same function with one connection. It sets on the generator and should have one wire, the Yellow/Black, going from it to the terminal by the fuse. I will attach a wiring diagram if it helps any, VanPelt has a lot of them on his site. I might attempt to draw this out for you, sometimes the wiring diagrams are a little hard to follow if you are not accustom to them.

See if this helps. I believe the cut wires would route as follows:

Two wires go into the engine conduit - Coil (Red) & Cut-Out (Yellow/Black)
One wire goes to top of bellhousing - Oil Pressure Sender (Black/Yellow)
Two wires go to/from the steering box - Power to light s/w (Yellow/Red) & Instrument Lighting (Blue/Black)
One wire goes to the floor starter switch - Battery Power (Yellow)

Note: some of the color coding can be switched, such as Yellow/Black vs Black/Yellow. For some reason Ford seems to switch them back and forth.

JS , I have the book that I believe that schematic appears to come from and I agree that these are sometimes hard to follow if you do not do it everyday . What I was going to attempt to do is draw my own based on the info you supplied and the attached drawing . My guess is that the cutout is on top of the generator or in the Voltage regulator[?] on the firewall of my truck that is already there .
What I wish to do is get the motor in the truck and running using the axillary start switch on the firewall solenoid . Once I do that I will replace wires one at a time and add extra circuits and switch's for lights etc.

If you have a simple diagram that you could spare or link to it would be greatly appreciated . One day I will be able to "rip it all out" and rewire and help the next person but today is not that day
Thanks

Super , I have the Ford book that have the diagrams attached above , I know there are basic wiring principles that apply to all these older engines of any type and I am going to try and put one together that is easy to understand and pass it along with the help that you and others are so graciously supplying . and I will never try this on anything later than my 1966 Chevy truck... promise

Ok, now you changed everything! The stock 36 wiring is not going to go straight across to the truck wiring. That is a whole different topic. The cut-out on the 36 engine is the voltage regulator. If you are going to attempt to wire it to the truck regulator it will have to be setup differently. The 36 uses one wire to the regulator (cut-out) the truck uses three, a Field, Arm and Ground wire. The 36 used a floor mounted starter switch, your truck uses a starter solenoid. Believe the light switch is totally different. Your best bet would be to forget about how the 36 was wired and work on how the truck is wired. So, for a start, what year truck and and what engine was in it originally?

JS , once the 36 is in the truck running all the truck wiring is going to be history and I will wire each circuit separately from there and use a start button . At this stage I just need the truck to run as it is 3rd down on the list of projects . If I had not found the engine I would have gotten to next year ...maybe

You can not just wire it up! Needs to match the truck wiring. What year truck? Can't help you if I have no idea what your working on. If you want to use the 36 generator and cut-out you will have to by-pass the regulator on the truck. But any way you go you are going to have to change a few wire around.

JS . It is a 1941 truck , when I bought it there was a frozen motor [ since freed and apart ] Someone had ripped all the wires off the engine and what were left were laying in the engine bay . Under the dash was a nest of splices with 4 after market toggle switches attached......also the switch in the column had been replaced with an after market drilled through the dash ... and I really appreciate your help on this

Ok, some of these will end up trial and error, but hear goes. First I am assuming that you just want to get the engine wired so it will run. The 41 Truck should have a Circuit Breaker (CB) & Ignition Resistor next to each other under the dash. You need a Yellow wire from the Battery side of the starter solenoid to the amp meter then on the to the far right side of the CB. This assumes that the CB in the truck matches the wiring diagrams. It should be the post on the CB with 3 or 4 wires connected to it. Two large yellow wires, a yellow/black wire to the ignition switch and a cigar lighter wire (this was an option). Then you need a yellow wire from this same post on the CB to the BAT post on the Voltage Regulator (just using this post for a connection point, the Voltage Regulator will not be used). The yellow/black wire on the 36 engine harness connects to this BAT terminal on the Voltage Regulator. This wire goes to the cut-out on the generator. The generator will use the cut-out for voltage regulation. Back to the CB, from the same post with the yellow wires you need a yellow/black wire to the BAT terminal on the original ignition switch, on a universal switch it should still be labeled BAT. On the original ignition switch there is a coil terminal, there would be a black/red wire from there to one side of the ignition resistor (next to the CB). On a universal switch this would be the RUN position. From the other side of the ignition resistor run a red wire to the coil. The last position on the original ignition switch is gauges with a black/green wire running to the temp gauge (the terminal with the strip connection it to the fuel gauge). On a universal this could also connect to the RUN. The same terminal of the temp gauge then connects to the oil pressure gauge, also with a black/green wire. The other side of the oil gauge connects to the sender with a black/yellow wire. Backing up, the temp gauge connects to it's sender with a black wire (don't think you had this sender on your 36 engine, might move it over from you 41 engine). The starter connects to the other side of the starter solenoid. The starter solenoid is activated by pressing the start button, which connects to the solenoid with a black wire. The other wire on the solenoid (yellow/green) is a horn wire and I wouldn't worry about it. That should do it, I hope!
It is possible that it was rewired to not use the start button and with a different type of starter solenoid. If so, let me know, it will wire up a little different.

JS , I believe I am up to this challenge ..... give me a couple of days for an update
Thanks

Ok JS I started fishing through the rats nest of wires , there was everything from factory to 12-2 house wires in there ....after I separated circuit wires for lights / wipers etc. I started to work on your suggestions.

Below are some pictures that may or not be as described in JS's post above

1] circuit breaker { fuse box ?}
2] Ignition resister ? Or ?

the third picture ?
I am assuming the cut out sits atop the generator
