Long Report on the problem, support from the factory, and the repair of The Rocky
Mountain Instrument - MicroMonitor.
Do Not Archive
During the building process, I had to decide which engine monitor I wanted yet
could afford to install in my plane. Remember, this was before the latest several
monitors became available. Anyway, RMI unit was chosen. I have a friend
who is Electrical Engineer and he said he said it would be fun to build the unit
so the kit was ordered. During the assembly process, he reported that it
was the best electronic kit he had ever worked on. During installation, two sensors
didn't appear to work properly and the company quickly sent out replaces
after asking if we were sure that they were installed properly. Of course,
we said we were sure. After the sensors arrived, it was found the we had wired
them improperly (the company didn't say I told you so but were happy to learn
that we had solved the problem.
For the next two years, the unit worked perfectly and just as advertised. Then
the unit started to have problems. It would reset itself, lock up, and or just
display incorrect data. An email to RMI and they sent a troubleshooting manual
the next day. Again with the help of the EE, we started to find and fix
the problem. As we had not changed anything, it had to be in the "box" but test
after test showed the box was working correctly. Finally, we were able to
determine that three sensors that were acting up all used a 10 volt input. After
checking each sensor, we found that the connectors for the oil temperature
were no longer protected by shrink-wrap and was shorting out when the engine
was running. How does shrink-wrap disappear? I was sure that we never did any
maintenance on the sensor. Then I remember that we had removed the engine and
it turns out the over-haulers most likely removed the oil temperature probe.
As I had hardwired it, they had to cut the wires and it was up to us to reconnect
everything. (As a side note, when Jack Starn AKA KABONG starting helping
me over five years ago, I told him every good thing I would credit for and
he would have to accept all the blame for all the mistakes.) Therefore, Jack
didn't do a good job of putting everything back together.
Good - The RMI unit works great. The company support is excellent. Any problems
were user generated.
Bad - Jack. :-)

I have always found RMI to be a wonderful company to do business with.
Their Micro Encoder is the crown jewel....
