Losing engine gauges, speedo, and fan staying on

[Colter]

Do you have a 1117 code on the engine side? That would confirm power issue which is not abnormal but i don't think its the right direction.

If someone on your behalf could plug in with ESA that would be beneficial and can narrow the issue down in case there is something on the IP side causing problems. Unfortunately without an active issue if tough to find. I wouldn't recommend tearing wiring harnesses apart, stick to points where its tied up or braced, cut ties and check for rubs.
