 Posted: Tue Jun 21, 2011 3:18 pm Post subject: 914 Ignition Module |
 |
|
I had a bad ignition module which showed up as a very low rpm on the mag check. It was almost 900 rpm difference. Turns out it was the top module which fires the top plugs on the 914. I went thru the Ignition troubleshooting guide (see attached) it pointed me in the right direction. It was not firing the top front two plugs. I could pull the plug wires off and no difference. It was amazing how well the engine ran with just the back two top plugs working when I was testing just the top module. The engine kept running with just one plug firing on one cylinder as I was testing and pulling plug wires off.
The engine has under 500 hours and I cannot get any explanation from any Rotax people as to the cause of failure. They only say that failures are rare, and I might add expensive $950. All is fixed and I had a great flight today to a few of the Islands up here in the Pacific Northwest (looked for Fred on Orcas, didn’t see him:)

Hey Jerry...if you were heading north just east of the airstrip at about 1500 ft. ASL...say between noon and 1 pm or thereabouts...you went right over my house...engine sounded smooth and oh so quiet...I'm just south of the marker for Parker Reef.

I am sorry to hear about your ignition module problem.
We had similar problems with G-IRON (also a 914) and ended up having to replacing both modules.
It is obviously convenient for the supply agents to claim failures are rare. From what I hear from owners failures are far more frequent than they should be for such an expensive item.
Fundamentally these modules contain about $30 worth of parts. The supplier justifies the cost on the basis of quality and reliability which is just not being achieved.
Personally I believe it is long overdue that Rotax should replace any module that fails free of change.

We had a failure of a unit at about 500hrs too! Thought it was 'just
one of those things' - Rotax really should put their hands up and admit
that the device is not up to the job and either replace the units FOC
or at least much closer to cost price - I think that the boxes cost
about 6-700 GBP.
