Had the same problem of overvoltage but could not
eleminate it by trial and error, knowing the EC3 was available maybe I did not
try long enough.
For the magnetic particles, I did clean the CAS to
make sure that was not the problem.
Thanks

Bill,
It has been a while, but from what I recall of my problem with the
Renesis CAS was that the output voltage was too high and would
overpower (technical term) the EC-2. The solution was to install a zener
diode and resistor in the CAS circuit (values determined by trial and
error).
FYI, I converted my old style CAS to the crank-mounted CAS. Without
knowing any better, I fabricated the CAS bracket out of 4130 (didn't want any
failures on this part). Turns out, any ferrous metal nearby the CAS will
corrupt the signal. I stumbled across that bit of information in the
Renesis shop manual. It mentions that you need to keep the CAS clean of
road grime and metal particles. So, I made a new bracket out of aluminum
and it cured that problem. Live and learn!

Rino,
What exactly is it about the
Renesis crank angle sensor signal that the EC-2 can not
handle?

[FlyRotary] EC3 Controller
Anyone had a problem with the
Renesis crank angle sensor and had to change it. I may have to get a
new crank angle sensor, but first I want to check with you
guys.

probably gone to Colorado, maybe someone got this problem
before.
I cannot get full power on my
Renesis for takeoff on Controller A. Seems like controller B
works OK.
It is not the fuel mixture, I
tried that. Actually, when the throttle is wide open the mixture
display goes up and down rapidly, from full lean to full rich and the engine
surge.
I had a similar problem when I
first installed and started the Renesis. I had the EC2 controller then
and had to get the EC3 to fix the problem. Now it is coming back to me
on the EC3, I think. The problem then was with the crank sensor, the
EC2 could not handle the sensor signal at more than about 5000
rpm.
I think the problem started
progressively during the last few hours of flight, at first I thought it was
a fuel mixture problem and was trying to ajust for that but now it is not a
mixture problem. Since the controller B has NO temp. sensor and works
ok, I wonder if it has anything to do with that problem on controller
A.
