If the buzz box is hooked up to the mag its transformer grounds the mag. But
why take a chance that the alligator clip should snap off when you are
rocking the prop.

Perfect! I knew they existed but hadn't gone looking for a source yet. Thanks
for the pointer.

There is a time to laud one's country and a time to protest.
A good citizen is prepared to do either as the need arises.

--> Yak-List message posted by: "Gus Fraser" <fraseg@comcast.net>
There I was, at the East coast session this weekend, performing a lovely
hammerhead when, just at the top, a very smelly puff of blue smoke emerged
from the instrument panel. Throttle back, fall out and recover while
scanning the generator failure light illuminated. Headed back and landed
wiped out the fuse box access panel, Imagine my surprise when I found the
fuse board box screws had come loose at the top so the whole panel was
pivoted on the lower screws so that in the hammerhead it must have touched
something. So, I opened the box expecting to find a blown fuse, did I find
one, did I f
&k. What I found was a wire that thought it was a fuse. The +
wire from the generator to the regulator had TOTALLY fried itself. I left
the plane there as Morty, thanks Morty, said he would replace the wire this
week. After looking at the circuit diagram the wire goes straight to a fuse
but does include a capacitor to earth on the live side of the fuse. I
suspect, but Morty you will have to check, that the capacitor has short
circuited and as the wire had no protection it fried. This is one of the
very few design faults on this aircraft. I suspect that the capacitor should
be on the downstream side of the fuse.
Has anyone else seen this failure ?
Folks the next time you have the side panel off check the security of the
bolts that secure the power panel. They are not wired in and as there is
potentially 170 amps in there you don't want to start welding at 6G.
hope this helps
Gus

I have a weird problem with my Yak. Very smooth engine operates with no
problems at all power settings until fuel state reaches 15 litres each
side. Then I have an intermittent miss (about every 2 minutes. No
change in fuel pressure or any other parameters, just a quick cough
then smooth again.
Any ideas gratefully received...
Cheers
Bryan
