Roger,
I did follow the circuit and think I found the problem (but can't be sure
until the weather clears and I fly the plane).
A fuselink between SW1-4 (which powers the Alternator controller coil) and
the Alternator controller was blown. It likely shorting out during
construction because it isn't shorting now.
After spending 9-hours trying to track-down the problem I have a concern
about using fuselinks. Unlike a fuse, you can't see that a fuselink has
blown. Had I used a fuse rather than a fuselink I would have found the
problem in minutes!
Since my fuse holder is right next to this fuselink and I won't expose the
circuit to extra lengths of non-fused wire, I plan to replace the fuselink
with a 1-AMP ATC (bayonet type) fuse on my main buss.
Regards,
Les

Its been quite awhile since the service bulletin on coolant temperature
was issued.
Has anyone actually installed a coolant temp probe? If so, did you choose
a hole in the expansion tank or a tee into the line to the radiator from
the tank. I have not seen anyone offer a standard solution for us poor
homebuilders!

I installed a temp guage on my 912s. Installed a "T" near the expansion
tank for the probe.
I'm seeing about 165 degrees F. I'm running a 50/50 mix.
