SUN 1115 is a rather competent , old style , tester. The quality of the SUN machines wen it comes to design, manufacturing, components is first class.
I have a 2110 which is the first menu-based digital tester around.
A few things, although I do not know any particulars of the 1115 and the picture posted shows only general view:
The CO/HC meter is an IR based unit with rok solid electronics. BUT the two sensors and their optical filters are tricky, spares are generally impossible to get: There is a uy on this board who helped me out, he had the 2 last in the universe!
The HT clamp ( big shiny chromed part) is marvellous and lets you study the ignition waveform on the CRT.
The magnetic timing pickup needs to be put against the flywheel at 20 degrees BTDC. You can then read the ignition advance on the scope. Works great.
The green AmpClamp is a very early application of a Hall sensor when it comes to automotive electronics. If undamaged mechanically it will work.
The test cable plug in at sockets on the cable boom.The connectors used are really solid stuff, but will be hard to find new, I think. But there are modern stuff that will do the job.
SUN was cuttng edge in all aspects of electronics. So , some of the sensor semiconductors used ( if there is an electronic MAP gauge like on mine) can be hard to find, But there are modern replacements, and with a bit of tweaking all will be well.
It is a nice piece of period tester and will elevate the status of your garage immensly, from an aestethic point of view.. If uou are into the cars of the 50/60´s its great.
My 2110 sits unused more than 364 days of the year. But it looks super. And when I ocasionally get a 70´s MB to fool around with it does the job better than any other tester.
