Unit was advertised as a SKY-TEC Starter Solenoid but a preferred Lamar Solenoid was received with the same P/N and PMA documentation. Easy installation on a Mooney but when using the original mounting holes, the unit will be mounted horizontally instead of vertically. Lamar tech support verified that the unit can be installed in any orientation.

I believe this is a better quality starter than the one I had in my Beechcraft A35. The only issue I ran into is that the mounting holes had to be reamed because my firewall mounting is narrower than the smallest spacing on the Solenoid. I needed to gain about 1/3 inch in order to mount it. Also even though it is intuitive the instruction does not mention that the ground wire should mount to a mounting screw.

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.
