Just flew my first flight with the Plasma II and really like the 

smoothness.  However,  a couple of questions for those already flying 

this system.



I did my annual and installed a new battery and lower plugs at the same 

time as the el ign.  I kept my 300 hour left impulse bendix mag, which 

never ran quite as smoothly as my old mag.  I notice a definite 

improvement at low rpm.  The left mag idles roughly.  On mag check, Im 

seeing about a 125-175 drop at 1700 which is too much.  I just checked 

the timing and it was fine.  No adjustment.  I had to reroute wires 

after installing the el ign.  Im guessing if I had the wiring incorrect, 

I would notice a huge difference.  Anyway, I noticed two changes in 

flight.  First, my ammeter was sitting at about 18 amps, where it used 

to barely show any indication.  Secondly, my engine monitor is giving me 

a differential warning between warmest and coolest egt.  Im getting a 

102 degree spread at lower cruise power settings.  Ive always had a 

problem with one egt being high but now its tripping the factory default 

warning.  Im not one to ignore changes so I thought I would put this out 

there.  I can change the warning parameters and will probably do so 

after a little more test flying. 



Thanks

I can't explain the CHT spread and roughness except to suggest that

you check the aviation plugs for fouling.



The 18 amp is way too high.  On my Plasma III with comm (GNS 430),

transponder, etc, I an running 4-5 amps (or is it 7- with no nav lights 

(just strobes)

on.  Are your landing lights on?   Other high drain systems?



I have not flown for six weeks so my recall is fading.
