Electroair Re-install

[Dickard]

I've had nothing but problems with the EIS since re-install after major maintenance.  I'm a physicist, not an electrical engineer, but I'm thinking bundling all those wires is probably not a good thing.  Also, did a logbook review.  Blue ignition wires are ancient and show signs of burn through.  Gami's have about 500 hours on them without cleaning.  And on and on it goes.  Hangar neighbors keep telling me not to give up.  Mom says, "that plane needs to go to aircraft heaven".  Wife just gives me side-eye when another Aircraft Spruce box arrives.

Fired my mechanic.  Now talking with the guys at Smooth Power to get insight on the EIS.  It's gonna be a cold winter in the hangar.

I removed the electroair from my Bravo, installed slick start on left mag, call me if interested 804 402 4705

The Electroair installation manual specifically states that you must maintain at least 1/4" of clearance between the spark plug wires along their routes, and your installation clearly does not meet that requirement.  I would start there.  You'll need to acquire some wire loom separators...likely from automotive suppliers, and creatively route and secure them to accomplish this.

Are your blue plug leads from a conventional mag?  

EDIT:  I also noticed your EA plug wires are routed in parallel with your engine monitor wires, which is also not per the installation manual.  I'd suggest you get a better mechanic to audit the EA installation and correct all of the deficiencies before you give up.

Personally my advice is pull the electroair, put back in one of the mags and install a Surefly EIS in place of the other mag and be done.
Nothing but problems with the older Electoairs. (In contrast the new Electroair replacement for the dual mag has it a home run but that’s a different engine.)
Use fine wire plugs rather than massives.
If wires show arcing marks they need replacing too.

Just that one picture I can tell it was not installed correctly. There is nothing wrong with electroair. Issues with mechanics that get in way over their head and cannot follow instructions. Thinking you can just slap something together not understanding physics, engineering, or general science. This goes with virtually everything not just planes.
So I would get with a good mechanic that has a track record of installing them and Electroair to get it worked out.

Yes, the blue harness is for the mag.  It's about 15 years old and showing areas of burn through.
