Just picked up this engine analyzer. I would like to get it back in working order. If anyone has a service manual or wiring schematics, please let me know. It is an SS400 model. Thanks
Congrats. That's a good score. Can't help you with the manual but they pop up on eBay frequently. These old Sun scopes are great. I picked up a 1015 last year.
I started out on a 1015 in 1979....it was and is an excellent piece of equipment for diagnosing non computer cars, and even computer equipped ones. You can do tons of stuff with it and it is a time-saver.
The Infa Red scope in the first post is as good and more complex....and a lot older. Early 1960's at the newest. Neat stuff, glad to see it out there!

That looks like the same machine that came to town here in 1963. All the guys were raving about this shop that had this piece of equipment. It'd almost tell you how much air was in the tires. $2.00 scan fee!
So I hustle my 245/265 with 100,000 miles on it down to the shop to get a check up. The guy told me, among other things that I had no compression on two cylinders and very little in another. I didn't believe him at the time but a few miles down the road, it turned out he was right The thing seemed to run pretty good though..
When I bought my '65 GTO in 1982, the very first thing I did was take it to work and put it on the Sun scope. The ignition pattern on 'display' was upside down.....which told me right off that the ignition coil was hooked up backwards. I fixed that, and the car felt like it picked up 50 HP instantly. Learning to tune cars back then with points, carbs, and adjustable 'everything' with these machines really provided a solid automotive diagnostic background for me. You learned in real time under the hood what worked, and what didn't, and could tell at a glance at an ignition pattern if all was well or if something was wrong. I miss those days. Today, without a scope, I use a vacuum gauge, timing light, my ears, my eyes, and my nose to tune up my old cars.....and sometimes a DVOM if I suspect I have a bad wire. Sure miss those old Sun scopes!
That is the scope I was trained on back in the early 70's. I used to do some of the training for Allen scopes and I wrote an article on pattern interpretation. If you would like a copy send me your email address.
If you have any questions do not hesitate to ask, I might even remember the answers!

Anybody know what year this one is? I plugged it in and got a trace on the scope then I saw smoke. Not sure what to do with it now but I'd sure like to use it.

Is that the one you got from Rodger Penske a few years ago Verne? Here's a look at a late 1950's Sun catalog I've got...
...that shows the 900 featured.
Since they refer to it as "the great new Sun 900" it would seem it's from the late '50's. I'll check tomorrow and see if the catalog has a date in it anywhere. That should help you narrow it down.

Sounds like the big electrolytic cap went in the power supply. Common occurrence with stuff this old.Not hard to identify and replace.
Thomas,
The resolution of your pic is not quite high enough for me to read the catalog info. Can you tell me what this position on W Guy's scope is please?
