• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

74 scout 2 lock position for key power stiil on?

Got my 74 Scout 2 about 8 weeks ago. runs good but now i keep having a battery drain issue. I noticed this weekend that when i take the key out in either the lock position or the ON position, the fuel gauge seems to be on. I can also turn the fan on, the headlights and other electrical switches like wipers etc.. Should all of that work with the ignition in lock or ON? when i say on, its the first position after lock. i can remove the key on this rig with the motor running or not and in any position.

So to my questions? should power be available when the key ignition is in the lock or next position? do i need a new ignition so the key just doesnt come out when its running? also noticed that my blinkers didnt work during an evening drive when they worked earlier. now they work fine the next morning... Any help here would be appreciated.

1974 scout 2
345 V8 motor
Holley 2 bbl carb... fairly black in the inside.

New queston. should this motor and year have a choke? starts hard and usually have to use starter fluid direct into carb. parked on a downhill driveway most of the time.. not that i know if that matters.
 
Sounds to me like you need a new Key tumbler installed. They are cheap but you need a steering wheel puller and lock plate remover to get to it.

1) Key in 'ON' position: all electrical gauges and functions will operate.

Key in 'LOCK' position: all gauges inoperative (except ammeter), and only the interior lights & exterior lights will operate.
No fan or radio or wipers etc.

I agree, ignition lock cylinder & key are worn excessively.

2) Choke....yes your carb should have an automatic choke of some type.

Typically a divorced choke on the right side of the carb/intake manifold with a vacuum operated choke pull-off device on the right rear of the carb would be standard for that year and carb.

It may need adjusted/repaired or it may be missing or it may have been replaced by a manually operated choke cable or something else, .....?

Orientation of the vehicle should not matter.

Please take photos of the carb from each side and post them up on this thread.

Thanks for the quick reply! I will take some photos this evening after work. The pictures will make more sense for the choke as I think the previous owner has some spring jerry-rigged on to the carb.

For the new ignition tumbler.. Do I have to get new keys as well or do I want to stay away from the semi worn out ones? I want to replace the steering wheel anyway so I guess it's the time.

I saw somewhere that you need a conversion or adapter kit to change to an aftermarket steering wheel? True?

Thanks again!

If I recall correctly, the actual ignition switch is located down near the bottom of the steering column inside the truck. There is a long skinny rod type thingy that goes from the key lock in the column down to the actual ignition switch. If the switch itself is sticky, the rod may be deflecting and not really activating it. Nice looking Scout.

Thanks all for the help here. I am posting the pics of the carb and steering column. had a good call with someone at IH parts about my ignition. i have some work to do but any more ideas are appreciated.

as you can see in one of the pics. there is a spring on the choke side that the previous owner added.

First, thank you for the photos.

Re: Choke Issue....

Your Scout has a "divorced choke" which is the metal box attached to the intake manifold on the right side. In the box is a coiled flat spring which operates the vertical rod that is attached to the choke plate linkage.

The "choke pull-off" is the vacuum operated device on the right rear of the carb which also attaches to the choke plate linkage.

In order for you to have a normally starting and functioning carb & engine, both of these have to work properly.

The "PO" in your case has installed a coil spring which is defeating the purpose of the two choke controlling items.
I would assume one or both of the divorced choke and the choke pull-off are defective and / or the divorced choke needs adjusted.

I suggest you remove the shiny coil spring that the PO installed and see how the choke operates without it.
Try starting the Scout and see what happens.
After you do that, and reply with results we can regroup to see what needs to be done next.

NOTE: the choke pull-off is easy replaceable and was a common failure item when carbs were commonly utilized. The divorced choke is adjustable in two ways: 1) by bending the operating rod a bit at a time, and 2) by a screw & lock nut on the front side of the stove which adjusts the tension of the internal spring.

Ok. So removed the spring.. took all the parts off and cleaned them up and made sure they worked. Put it all back together... what a sweet sound to hear it fire up on the first turn of thee key. no cranking. no starter fluid.. nada... ran great. adjusted the idle a bit as it was really fast. Thank you!

On a down note... took off the steering wheel shroud and could not really see anything in regards to the Steering Column Ignition Switch Sector & Rack Gear

this was the plastic part at the base of the column where it meets the dash.

I was told that this may be what is not moving enough to disengage the key control into the ignition switch.. keeping power to the fan and wipers when in lock and off key position.


Does anyone know what the part is that i labeled as 'unknown part' and 'unknown part 2"? this was connected to the choke


Any thoughts?

Quote - "Does anyone know what the part is that I labeled as 'unknown part' and 'unknown part 2'? This was connected to the choke."

That is a electrical choke heating element.
It is explained in the Service Manual.
Not all carbs have them.
It only operates for a few minutes when the engine is cold to assist in opening the choke as the engine warms up.

Not really necessary in my opinion.

Thanks.. Service manual is ordered. Just not arrived yet. I don't live in a cold enough climate to need it... But I'll leave it where it is.


Any advice on the steering column and how to got to electronic element for the key? Having that as my constant potential power drain is a worry...

Thanks again

Choke - Yes, you will probably be fine without the choke heater. My truck has the divorced choke and vacuum choke pull-off (without the heater) on a ThermoQuad 4-barrell carb and it starts just fine: hot, cold, cold soaked, you name it. Start it, idle for 60 seconds, drive away.


Column - FYI, the Scout II steering column is a Saginaw (manufacturer) unit.

Saginaw made millions of these steering columns for GM cars & trucks in the 70's and 80's. They are identical to yours except for minor differenced like overall length, mounting, color, and style of steering wheel.

My point is, there is a plethora of info on the Saginaw steering column on the internet (You Tube) that one could easily find if they so chose.

Other people with more experience on these units than me have already made the videos, etc.

Here are a few pictures showing where the actual ignition switch is located. The arrow in the ignition switch picture is showing the back of the switch, the front is hard to get a picture of. The switch is difficult to access, which is probably a good thing. The arrow on the copy of your picture shows the actuating rod, it should move when you cycle through the different switch positions. The bundle of wires going up into the top of the steering column is for turn signal switch, emergency flasher switch, and horn.

I was able to see the accentuator rod move up and down with the turn of the key. I was actually able to move the rod manually and turn off the car.

So I know it moves. Its a matter if something is stuck below that keeping the circuit open in some way that is allowing for the accessories to still be able to be used when the key is in lock position.

I will keep investigating. I did order the new key tumbler to install so I cant just pull the keys out when its running. in the mean time I am going to test the power being pulled as it sits in the driveway.

Thanks again...
