I replaced it with the Sky-Tec 149NL. The LS came as the standard configuration of the Lycoming IO-540 for the RV10 one could order through Vans back around 2009. People in the RV10 community quickly determined this was not a good combination.

This was SOP on cold days but it never actually failed to start the engine.

Lycoming and Sky-Tech came to the same conclusion at the time and specifically recommended that the LS is not a good starter for this application. For a period of time both companies were taking exchanges of the the LS for the NL at no charge. (Sky Tec now offers an XLT model as an updated replacement for the LS. Some RV10 builders used the HT model but reported similar problems.) When I replaced it with the NL, it was immediately apparent that the NL turned slower but with much greater 'authority'. Even starting on one battery, switched so that it ran on the same bus as the (3) EFISs, the EFISs didn't reboot. Starts are now a no-brainer. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ________________________________ Message 5 _____________________________________ Time: 11:32:12 AM PST US From: "Robert L.

So... here's an alternative for switching cameras to a monitor or EFIS input using a couple of voltage regulators and three ICs. All components are through-hole. Everything on a single PCB, and no relays. Reference the attached schematic: An LM2931 5V linear regulator and a TC7660 charge pump provide +/-5V rails to power the circuit. A 555 timer is configured in astable mode to provide an output with adjustable period of about 3 to 10 seconds. This output is fed to the clock input of a CD4022B octal counter. The clock signal can be interrupted by a SP3T ON-ON-(ON) switch to stop rotation of the cameras or advance them manually. Outputs 1-3 of the counter are connected to the logic inputs of an AD8184 4:1 video multiplexer such that they cause the multiplexer to cycle through its four video inputs, connecting each in turn to the output. RCA connectors provide four camera inputs and one video output.

Suggestions? If there's any interest, I can gin up a PCB.
