Hi,
Well that’s nice to know, that you are a trainer from text books.
Text books have workshop manuals with answers in the back or a teachers guide in a drawer!
What has happen here is not a textbook event.
You need troubleshooting skills and I’m sorry to say but that sometimes that comes through a hard knocks education! You raise up and scratch your head a lot but if you hit something on the way, that is wrong, you learn not to hit that area again! Same goes for a bump on the head!
You have to think through the processes of what your inputs need to be, to get a resulting output!
Sometimes you have to work backwards or know where the middle is!
I read your original post and figured out that you said, you attached vise grips to turn the wheels.
There are only two places, as I mentioned and logically there is not much room down below to spin the tool around and around!
I got a “handle” on the lack of information from your post or I call this, a non-textbook mistake! He was probably wanting to spin it fast to evacuate the air out of the rack. If the steering wheel was on why was he using vise grips? There was the thing that generated my response!
I tried using the link on Trev29’s post to get diagrams but even registering didn’t get me anywhere near any files. That site is messed up for a simpleton like me!
A diagram is useful and a voltmeter is like having a Lions nose to follow a trail! Without it, you might as well sit down and have a beer!
If you are more than a trainer, you should know how to use a voltmeter. Medical devices or any electrical controls use logic! Inputs & outputs!
So, we now know you at least arced the horn wire!
If you had the surrounding covers off or the control stalks dangling about is another thing!
Did you have wires loose from their terminals around there too?
If so, there are a host of other avenues of circuitry to consider.
By any chance was the cluster out of the dash too? I know of stranger things to be done out of carelessness or taking short cuts!
You found one short already substituting the steering wheel. (:-)
Stop being a trainer and turn on those eyes! Be an observer with ears and even a nose for burnt connections. Feel for weak spots under wire insulation. Get them senses working for the answer!
The best thing to do is to follow the first rule of troubleshooting and that is to follow the power supply coming into the systems.
Identify any systems not working on the way in.
Let this paint a picture of breakage in the power supply circuit.
It could be as simple as a corroded terminal that got overloaded right at that crusty point.
Someone could have added an in-line fuse someplace thinking they were protecting a radio or anti-thief system. That would shut down the power to a crucial component!
Keep us posted on your Safari hunting days!
