Marauder Posted November 16, 2021 Report Posted November 16, 2021 Does anyone have a digital copy of this wiring diagram? I have a paper version and I am trying to trace where the power for the flap indicator light comes from. My wiring diagram is on 4 pages and shows 21LP55A18 is the power lead but it doesn’t match up with the actual wire code I have and it doesn’t show where this wire originated from.

Yep haven't found any in stock with the major electronics places. But they can be special ordered at $35 each with a minimum order of 10. Ugh. Quote
Marauder Posted November 17, 2021 Author Report Posted November 17, 2021 The worst part is where they mounted it. Center of the panel behind the throttle quadrant. Fortunately I know a 3 year old with small hands. Wonder if this constitutes a violation of a child labor law. Quote

I'd be more concerned with WHY the fuse blew, than with finding a suitable replacement. I'd just fit in a properly rated cartridge fuse; you can purchase them with pre-attached leads. Quote

If that fuse/transistor panel didn’t require a whole lot of disassembly to get to, I’d probably have some adjustments made. I’ve owned the plane for 31 years and never knew exactly where this panel resided. I always thought it was tucked up with the shower of sparks or somewhere closer to the breaker panel.

And I’m pretty sure I know why it blew. There was a broken wire at the rheostat. The plane goes in for annual tomorrow and we will confirm the circuit integrity.
