So far it’s working as planned. I also replaced my battery with EarthX the engine turns over much faster.

This was a simple drop-in install on my 74 A185F. Comes with wiring diagram. Looks like quality construction and works as advertised for my 12V system. Hope it lasts the coming 49 years, like the original.

My Lycoming I0360A1B6 was cranking like I had a failing battery. The SKY-TEC STS-M12 returned my cranking RPM like a brained battery.

Replaced my original master/battery solenoid on my RV10 with this one. With my high CCA Li battery I needed the high in-rush this product provided versus replacing with cheaper versions. Included wiring diagram helped with install. Original was a 3-post. This is a 4-post. Still early in trying out phase but so good, so far

to replace an original equipment solenoid in my OLD Mooney, this is the only game in town (and at a reasonable price too). it fit just fine and operates exactly as expected. as usual, no complaints with anything from Aircraft Spruce.

This is not a direct replacement for a master solenoid. This product takes advanced knowledge to wire it correctly and the directions provide are as clear as mud.

Replaced old solenoid after I was having starting issues. This performed better at first then the same performance later. A month ago it totally failed in Northern Maine on a very cold day- had to bypass to get out of there. Long of the short: This isnt worth the money. Still fails, when you least want it to.

We installed them on 3 of the Cessnas in our rental fleet. Had problems with one of them dropping out in flight. Complied with the service bulletin and Hartzell sent 3 new units. One of the new units in a Cessna 150 failed ON after about 60 hrs. We were able to bring a flat battery back. Hartzell replaced the unit for free. The replacement unit has now also failed ON after 45 hrs.

Ever since Ive installed this contactor, Ive had an intermittent issue where the master doesnt always turn off if the engine is hot. When the engine cools off again, the master turns off.

This is a replacement for an identical master solenoid (STS-M12) that was in operation for less than 6 months. The previous solenoid would make a loud click when I turn it on but would not make contact across the primary voltage wires. This would happen intermittently. I inspected all connections and battery - which were all like new.
The description states the Silver Contacts provide 300A in-rush & 150A continuous-duty capability Much higher than OE units. I removed the cap on the solenoid and did not see any silver contacts - They are copper contacts. I would like to have an explanation of what do they consider silver contacts. I certainly did not find silver inside. Very disappointing.

Installed in my E-AB. Aircraft is yet to fly and this product failed with under 100 cycles of use. Only has been turned on to test/calibrate. Solenoid actuates but the contacts internally have glazed and it does not permit power to flow through. Shows 13.6 VDC in but 0.22 VDC out. Would not purchase again.
