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.

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.

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.

This product fit in the mount and to this point accomplishes the intended task at a fraction of the OEM part.

Good fit. Solid construction. No more jiggling battery leads to get relay to engage.

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.

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.

Performed exactly as advertised. Quality product. Outstanding service.
Ответ:The coil terminals are #10's and the power terminals are 5/16ths. It is recommended to mount per the airframe specifications. If none, it is recommended to mount with the cap up.
Ответ:Per Vendor: This product does not include the diode. You do not need the diode for the part to work correctly, it is simply a safety precaution some like to take. The airframe manufacturer might have a diode they recommend.
