8. Now I need the list's help: I need voltage measurements from a known
good ISCU unit, to try and find where the problem hides. It's
not very
difficult - all you need to do is connect a low power 12V source (wal-wart
seems safer than 12V from a big battery) to pins 15 & 31 as described
above, and tell me what you measure at all the other output pins. Also, I
need you to connect a low-power test light across the outputs (St1
andHi Chuck. What's up?
St2) and tell me if it lights or not (it should IMO) or even a small
loudspeaker to know if it's a variable signal.

damage **


Hey Tinkermn,
Have you had any response to this request? I just pulled all tthe good
bits form an 86 Vanagon on it's way to the crusher and could get you
those measurements if you still need the data. Why not just a DVM
across ST1 and ST2?

 It would be awesome to make these units bulletproof.
