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.

The break was inside the insulation, and one could NOT see it from the outside at all.

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?

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.

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. -------- Roger Lee Tucson, Az.

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.

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. -------- Roger Lee Tucson, Az.

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.
