Great news Andrew.  Just looked up my fueltek wiring and the CAS is the only shielded wires in the loom.  Neil

In my quest to find the elusive gremlin that made the engine miss when transmitting on the radio, and after fiddling with wires associated with radio & efis with no improvements, I finally got to the CAS wire (by this stage I'm just cutting & replacing wires) but didn't have enough on hand to replace it, But found a cable roll of 2 wire shielded in the corner of the hangar (owned by an sparky) and borrowed a bit just to try. Well, it must be better quality as ran engine up with no more miss at any rpm while transmitting, so here's hoping I found the buggar.

Update: ended up splitting coil power into 2 circuits, leading/trailing, with independent feeds/fuses/switches, now can check ignition on A & B ECU rather than just B as per EC2 wiring. Also cleaned up a bit more wiring as I had inadvertently created a ground loop on my radio to efis serial cable by connecting the shield to ground at both ends by mistake. Radio works better but now an old problem has returned that I thought I had fixed as Tracy had years ago, given instructions on installing some part to the circuit board, when I transmit on radio the engine misses, think the injectors are going full open and flooding engine again. seems to only happen in flight which has got me buggered as the engine cannot know its flying.

Going to try rewiring components back to the battery. as now I think it could be something to do with the battery being moved for CoG and components losing their independent feeds & ground back to the battery.

Interested to know what usually causes the breaker to trip?
Is it common to get an amp draw intermittently higher than breaker rating from components that does not really justify increasing wire size & breaker rating?

Up until this corrosion incident fuses have worked for me, But have always used fuses & wire size much higher than component requirement, that way if a fuse blew, there was a substantial fault somewhere that caused it. btw. only time a fuse has blown is on the ground when some idiot stuck a screwdiver where it shouldn't go. but then I haven't flown much either to say it wont happen in the air.

I use Corrosion X on any electrical connection I think may need it.  But I don’t use fuses on anything in the airplane.  Just a personal hang up.  Having a manually resettable breaker has saved me lots of times, even on non flight critical stuff.
