Yes, bench testing on the E= C2 version is complete.  Don't know what vintage your EC2 is but the early ones did n= ot have O2 sensor inputs and can't take advantage of the closed loop modes.  That is unrelated to the possible cause of the hiccup though.

I currently have a separate ground from= each of the batteries to a Nuckolls =E2=80=9Cforest of tabs=E2=80=9D ground p= oint.  Everything inside the cockpit grounds here.  Also the fuel pumps and injectors ground here.  The coils ground on the center iron.  Ther= e are separate grounds from each battery to the PSRU plate on each side of the= starter.  I have considered bringing two separate grounds from the cent= er iron to the batteries just in case there is resistance getting from the cent= er iron to the PSRU plate.=

I am also taking all my grounds apart t= o check for corrosion or anything that seems that it might not be properly bonded.

 

I am doing this for two reasons.  One, I am still getting that occasional =E2=80=9Chiccup=E2=80=9D that is vio= lent enough to shake the plane when it happens.  It is bad enough that I am concerned that i= t might be bad for the pin in the PSRU.  I am also wondering if it could b= e the PSRU that has sheared the pin and is slipping?  Someone on here had= that happen and I would really appreciate a description of what that sounded= and felt like and also how I could make certain that is not the problem.&nbs= p; No, I don=E2=80=99t want to dismantle the PSRU to check it unless that seems= to be the only way to check it.<= /o:p>

 

Also, Tracy, how are you progressing on getting t= he upgrade for the EC-2 that might fix this hiccup if that is what it is? = I think you had it done for the EC-3 and were working on the EC-2 implementation??=

 

The second reason for going thru the grounds is that I am having an intermittent problem with my GTX327 transpond= er, MFD150 moving map, and TruTrak autopilot shutting down.  This seems to happen more often when I key the mike on my GNS430W radio, but keying the mi= ke is not required.  It sometimes happens just out of the blue.  Also= most of the time, only the transponder shuts off.  Only sometimes does t= he moving map and autopilot join in the fun.

 

Everybody tells me that it sounds like a= ground issue, hence I am going thru the ground system.

 

I welcome all opinions and input!

Tying the engine parts tog= ether should not be necessary but you still need a separate ground from battery to airframe ground (if metal) and your avionics ground point.   Also separate feeds from +12 battery to starter/alternator and avionics.  You can Use= the starter/alternator feed for coils, injectors & fuel pumps to keep no= ise down on the avionics bus.
