Sun Engine Analyzer repair


Recommended Posts

Can anyone suggest a contact who will service a circa 1970 Sun model 1015 engine analyzer. I'm unable to get a full ignition pattern on the scope. It worked well when it was demonstrated at the time of purchase but I think the 400 mile trip home made for a problem.

I live about 100 miles S/W of St Louis Mo.

Thanks

Do you have the manuals with it? Are there wiring diagrams or schematics? If so, any good electronics tech should be able to figure it out.

Try looking inside for broken wires, parts jarred loose etc. It may be something fairly obvious, you never know your luck. Also look for burned or discolored transistors or diodes, and bulging or melted capacitors.
