I had the chance a few days ago to start my engine for the first time. Everything started up fine but I did notice a few issues that I need some help figuring out how to fix. I am building ELSA with Garmin G3X.
1. Oil temperature showed a gradually increase, but then all of a sudden dropped off (meaning gauge showed big red X). It came back up for a second, but then dropped again.) The 2nd and 3rd time I started the engine the oil temperature gauge seemed to drop off even sooner.
2. The CHT2 has a big red X. Ended up taking the CHT1 wire and hooking to CHT2 sensor and the sensor was fine. I tested the CHT2 wire continuity to the Firewall Forward pin and it was fine to that point. I am not sure where it goes from there or how to narrow the problem down.
3. The fuel PSI seemed to fluctuate during the 1st three starts of the engine. It would show fine in the range of 5 to 5.5 or so, then it would drop below 2 for a couple seconds and then back up again. It seemed kind of sporatic. I believe it was on the 2nd start that the PSI seemed to stabilize in the green and I thought my troubles were over, but then in the 3rd start it was sporatic again.
If anyone can give me some pointers as to what may be the issue I would greatly appreciate it. All of the other gauges seem to be fine. Could it possibly a grounding issue? If so, where do I look? Or could it be something else wrong?
Here are a few photos (if they post correctly) of my screen at various times and also the engine log graphs for the 1st three starts.
Thanks,
Nathan
