Deleted. I see you're looking specifically for a switch with a 10mm thread...

While I previously said 87 was not used, I should have mentioned the option of using post 87 for a low oil pressure warning light. The 87A in this case works as the NO line, 87 will be the opposite, it will be NC, hence when oil pressure is lost, this leg will close and energize the warning light. You can buy 1/2" very bright to install in your panel in a variety of placed.

Here are the ones I like and use...

Default Version 2 with oil pressure warning light

I decided to update the drawing. I added the master contactor that RV7 Charlie mentioned. I also added the low oil pressure light leg off post/terminal 87 on the relay.

When using warning lights, it is also good to add a "push to test" button so you can push it to ensure the lights themselves are functional as a preflight duty.

Default Panel installed and ready for engine run

Just over a month ago, someone asked when I could have the engine running on the airframe. Largely the hold up was building the panel. At least to the extent that it included the necessary gauges to run the engine.

Well I installed the panel today. It took a bit longer than I had anticipated but I am happy with the results.

Here is a pic of it installed.



Some of you will be surprised to see analog gauges on a current panel. When it comes to monitoring the engine systems I like gauges. Just me.

But when it comes to navigation, well that will be glass. That is why you see a fairly large blank area on the left. I am leaning on installing an IPAD and running foreflight for navigation.

I know I mentioned the "CPC" circular wire connectors previously, and I thought I would include a pic of those. They are hard mounted in the sub panel. I ended up using 3 9 pin connectors. This makes installing the panel, or upgrading it very easy. These connectors are readily available from Mouser, or DigiKey, or Ebay. They take wire anywhere from 22ga up to 14 ga. I did end up having to use one full sized Universal Mate-n-lock connector because my starter switch wire was 12ga and the panel feed line was 10 ga.

You will notice a white colored paper above each CPC connector. This is a list of what each terminal (wire) is as well as a diagram of the pins.



I suspect it will be a more than a week before I actually start the engine. I do have a bit of coolant plumbing to finalize and secure some loose wires, etc.

Feel free to ask questions.

Charlie

You're going to start the engine during AirVenture week - very appropriate...

That is a fine idea. Nicely done too.

That saves getting out a book and crawling up under there with it a few years down the road trouble shooting something. Good stuff Charlie.

Ross, funny you should mention that. Besides the fact I am not getting any younger, or skinnier, the thought of crawling on my back to look up at those wires behind the subpanel months or years later is not something I would look forward to.

But I actually do have several unassigned pairs of wires that transit the firewall that are stubbed off back there for use later. I probably should bring a few of them forward in to a pin on a connector before they get lost back there.

I am contemplating adding a "Air Temp" sensor in the cowling, more for my sense of curiosity but also as a "Canary" to catch something getting hot up there..... Maybe a Pressure Sender on the coolant system too. Just curious more than anything.....

Charlie

This is a good idea, with the belly radiator you will not easily see any indication of failure of coolant system integrity.
