| Subject: | Re: urgent: 912S ignition failure |
Remi,
I had this happen and the failure was in the red power wire from the back
of the engine to the module. I found it by using an ohm meter with a
sewing pin attached at one end of a lead and grounded at the other lead. I
worked my way along the wire from the module punching thru the plastic wire
shielding with the tip of the pin until I found the internal wire break. It was
on a flat run a few inches from the connector. It was totally invisible
from the outside of the wire
I cut the wire,spliced it ,and that fixed the problem.
Good luck to you

I had the exact same problem, first the one red wire, then the next, for
the two ignition systems.
The break was inside the insulation, and one could NOT see it from the
outside at all.

| Subject: | Westach Oil temp sender |
Hey guys, I'm only getting about a 1 year lifespan on my Westach oil temp senders,
part no 399S10-1.5S. They seem to quit all at once..i.e worked last flight,
then not at all the next from engine start up. Just wondered if others had this
as well or if it is something I'm doing? Appreciate any comments, thanks,

| Subject: | Low Oil Pressure |
I changed oil to the AeroShell Sport Plus 4 and noticed that my oil
pressure has been dropping since the weather has warmed. My pressure is
now showing at the lower limit of 30 psi in cruise. The oil temp and
water temps are fine, just a low indication on the pressure gauge. Are
others noticing this? It appears to be a viscosity issue to me since my
recent oil and filter change showed no metal particles in the filter and
everything else appears normal.
My plane is a Zenith 701 with the 912S and 150 hours.

Could be the sender if yours is mounted on the front of the engine. I
have changed mine about 4 times in 800+ hours.

I'm not a Westach fan. I have been using UMA gauges for the last 6 years and not
one failure. Flight Design has them in all their planes and aren't having any
issues.

| Subject: | Re: Low Oil Pressure |
I have changed oil three times now using AeroShell Light Sport 4 Stroke
oil in my early S/N 912 and have not noticed low oil pressures in flying
in the hot Florida Keys. Nor in the hot desert southwest.
However, At the last oil change with Shell 4 stroke, I changed out the oil
pressure spring, ball and retaining plug, as called for in the SB to
extend TBO. AND saw very high oil pressure on start-up immediately
thereafter (way up into the yellow) which caught my attention. Plus rapid
vibration of the needle in the gauge was present, worse at certain RPMs. I
had seen this needle vibration before when using a non-Rotax oil filter
and it had previously dissapeared when I installed a Rotax filter.
Not being sure if the vibration was caused by the new but maybe deffective
Rotax filter or the new spring, ball and plug, I called Lockwood and was
told to install a "Mushroom" type ball, which was engineered specifically
to control oil pressure gauge needle vibration. I installed the "mushroom"
style "ball" however it has a hole thru the middle which allows oil to
pass thru, at least I think thats how it works.
Suspecting that oil was bypassing the over pressure relief system thru the
"mushroom", I switched back to the original ball, spring and plug and oil
pressure was good, plus needle vibration dissapeared.
As an aside, a Shell Oil representative at the Sebring Light Sport Expo,
told me that the Shells Light Sport 4 Stroke oil is engineered with some
ashless disspersant characteristics to help handle lead if we use 100LL in
our 912s. Ashless dispersant is not mentioned on the container, because
someone might think it was OK to use in an aircooled Lycoming or
Continental. It is not. Heavy metal anti wear additives are added to the
Light Sport 4 Stroke oil to incease lubricity ijn our Rotax gear boxes.
The heavy metals will build up in Lycs and Cont. engine combustion
chambers, leading to detonation.

I doubt it is the oil. It is usually the sender. Put a mechanical gauge in line
and start the engine and compare it to the cockpit reading. This is the only
way, anything else is just guessing.

Dan,
I also use Aeroshell Sport Plus 4. My oil pressures have remained constant
from winter to summer. I flew for 2.2 hours this weekend with part of the
time at 90+ degrees. Oil pressure ran close to 70 psi.

Roger,
I've tried to download the new SI on running mods and I get a "Can't find the server"
error.
Tried your link and went to Rotax Owner and tried their link. Doesn't work.
