[quote="joeing701(at)internet.is"]Thank you all for the help. George, the installation
is not new. This problem just came up a few days ago. The starter has
not been inspected and I will have him check all ground connections.
Not sure when the fuse blows, after the ring engages or immediately. I will need
to get more precise information from my friend before we can isolate the cause
for the problem.
When I have more information, I will write again.
Best regards,

Have you battery load tested. If it's starting to go bad or if it is not fully
charged the amp draw will be higher than normal.

| Subject: | Re: High Oil Pressure |
I have the opposite problem. On the last flight, oil pressure was
consistently around 30 psi. After landing, I checked the oil level and it
was between the high and low marks. I cranked the engine and the oil
pressure stayed around 30 psi. I have about 40 hrs on this oil and filter.
I planned to change the oil/filter at 50 hrs.
I have another set of VDO gauges so I swapped the oil pressure gauge and
cranked the engine again. 30 psi.
I have another 912 so I borrowed the oil sending unit and put it on the
problem engine. I cranked the engine and the psi went to between 45-50
during 2000 rpm idle. I ran the rpm up to about 3000 and the oil psi was
around 40, maybe a little more according to the analog gauge.
This is an almost new engine. It has about 60 hours on it. The oil
pressure has declined from 60-65 at startup to the current pressure.
Before, cruise pressure was around 40-45 psi.
I am wondering what the next step should be? I am using the Rotax oil
filter from Lockwood Aviation and the recommended Mobile 1 oil. I plan to
change the oil and filter today and check it out.
Any other ideas?
Many thanks,

I also have EIS and my oil press reads 99 at idle, but in cruise oil
press reads normal although it jumps around a bit. When i pull the
power back for landing the press goes to 99 again. I temporialy
installed a oil press gage and it read normal at all rpms so I suspect
it is the Rotax press sender, which is expensive. Some have suggested
it should be mounted on the firewall.

you should clean off all thread sealant on pressure sender and see what happens

Thanks for the reinforcement Dave. I was going to order a pressure sender
tomorrow but will hold off for now. I don't like changes that occur
without reason. I use the EIS so all my readouts are digital and it really
jumps around after 15 minutes or so. Otherwise it is rock solid and runs cool
and smooth. I can't help but think its instrumentation. (I hope so). If I
find out anything else, Ill post it. thanks again

Try a mechanical gauge. I had same problem and it appears the problem
is in the sender. Rotax senders are a little pricey.
With mechanical gauge, the psi was back to normal.

Hello Scott.
I will have my friend check the battery.
Thanks for that input.
Best regards,
