--> JabiruEngine-List message posted by: "Jon" <jonh@flinthills.com>
Hello group,
I am working on a Zenith 601 XL with a Jabiru 3300 engine. We have installed an
Electronics International MVP-50 engine monitor system. Unfortunately, the
system is not functioning properly. Here are some symptoms:
1. When the engine is not running, everything seems to work properly.
2. When the engine is running, we see the following:
A. RPM value on display looks good
B. All values on the display associated with temperature (EGT, CHT, carb temp,
oil temp) read very high and fluctuate fairly frequently
C. All other values (volts, amps, oil press, fuel press, fuel flow, fuel level)
seem to read accurately most of the time except they fluctuate regularly
D. Error code "EDC" sometimes appears on various readouts (which EI says means
the sensor hook-up box is sending nonsense to the display box)
3. The comm. radio seems to work fine with the engine running, and there is no
appreciable noise.
4. Engine runs great and shows no magneto/firing problems.
I have talked to EI, Jabiru, local electronics experts, and Bob. I ran the sensor
wires as far from the "loud" wires as I could in front of the firewall. We
tried running engine with one alternator wire (of two) completely disconnected.
This had no effect. We installed a torroidal filter in the regulator output
wire; this had no effect. EI rebuilt the EDC-33P sensor hook-up box, and
this had no effect. We are contemplating having them rebuild the display box.
EI wants me to find an electromagnetic radiation intensity meter and take readings.
Can anyone shed some light on this problem?

Jon,
I know it's not very helpful to have someone reply with "I have no idea" but
at least you know the message was read!
We use other engine monitors like the Grand Rapids technologies EIS, Dynon,
Stratomaster, etc., and they all work fine if configured properly. This
means that I don't believe there is anything out-of-spec. with the engine
producing RF interference. I'm thinking it's the EI main unit not having as
good a noise rejection capability as other monitors.
Sorry I can't be more helpful.

Andy,
Thanks for your interest. Maybe this is just one of those unpleasant
learning experiences where we have to give up and try a different product.
Jon
