You're not gonna make one of us 'old-guys' feel even older by making us admit we know how to run one of those still - are you
They are really fairly easy to hook-up and us.
There should be @5~7 (could be a few more depending on options they ordered) wire leads coming off the boom - big 'bent-stick- thingy' hanging off the side - that are wired onto various components of the engine depending on the type of data you need and tests you're running.
There should be, at least,;
1.) High tension adapter for the #1 spark plug lead
2.) coil pick-up for dwell/timing to the coil lead
3.) voltage reference lead to the + side of the bat. or to the alt. output lug
4.) a vacuum line to hook into the manifold vacuum source
5.) a timing light
the above are the normal and necessary connection to do most 'tune-ups'
there may also be;
6.) a pile-resistor, to check starter draw and alternator/generator output
7.) a secondary vacuum line to connect to the ported side of carb to check advance signal or to allow advancing of the distributor for tests.
8.) several other component leads depending on options the unit has.
It looks like the unit also has several of the optional component test stations on it (down on the right side) these are used to test coils and other components off the car.
I won't promise I'd still have manuals for one - but I might ...
I donated a load to the old-car-manual project awhile back, but I don't remember those being with them.
I will dig through some old boxes out in the shop and see what I can find - this is goona take time, be patient
Hope this helps some;
an old guy
