SKY-TEC STS-S12 STARTER SOLENOID

February 20, 2024

This was a plug-n-play replacing the defective 49 year old original in a Cessna A185F. Sky-Tec also offers a Batt-Master solenoid which I elected to replace same time for the sake of reliability. Arrives with thoughtful wiring diagrams in the box.

SKY-TEC STS-S12 STARTER SOLENOID

Overall Great Product. The Blueprint Sheet Doesnt Explain to Well If You Are Going From A Three Post Solenoid To A Four Post. If You Had A Three Post Make Sure You Put The Ignition Wire On The Small Post On The Opposite Side Of The Aircraft Power Lug. Another Plus About This Product, It Doesnt Matter Which Side You Use For Aircraft Power, & Can Even Be Mounted Upside Down.

SKY-TEC STS-S24 STARTER SOLENOID BY LAMAR

December 24, 2022

This is used as a pilot solenoid in my Winco standby generator. My briggs and stratton solenoid pulled too many amps and would occasionally blow the ignition fuse. After wiring in this solenoid, it has worked reliably. This was the highest quality, most reliable solenoid that I could find for the money, that fit my application.

Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: How much does this Sky-Tec Starter solenoid weigh?

Without packaging, solenoid by itself weighs approx 1 lbs.The solenoid weighs 1.2 lbs with packaging.

Q: I am replacing the original starter on my 1967 Cessna 150G with a Skytec kit Kcst2. Which Skytec solenoid should I order?

For a 12V system see part number 07-03562. For a 24V system see part number 07-03563.

Q: Why is this Sky-Tec starter solenoid intermittent?

Starter solenoids / relays are intermittent, and Master solenoids / relays are continuous.

Q: What size are the terminal studs on STS-S12 starter solenoid?

5/16" on the main studs and there is a small stud that is 3/16".

Q: What is the distance between mounting holes?

2-1/4" hole center to hole center.

Q: Does this solenoid have an internal diode? The solenoid that I am replacing looks like it has a diode in the wire that goes from the S terminal to the mounting bolt.

There is no internal diode. These do not need a diode to function properly, but we always recommend hooking the new contactor up the exact way the old one was connected.

Q: What is the mount bolt torque?

Per the manufacturer: We do not have a torque spec for the mounting bolts. You would just tighten the bolts down to fully secure the unit.
