Reviews

100 amp continuous duty solenoid as expected, and shipped quickly. The instructions didnt mention, but I would recommend adding a diode pointing away from ground to the hot side of the coil, to protect solid state stuff from a hit when you deenergize. It functions as expected, and better than the antique I was using!

Works fine, but Lamar didnt mention the need for a diode on the install drawing.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. 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: What is the torque amount on bolts to attach this solenoid to aircraft?

We asked the manufacturer and they did not have any hard data available. The best answer we can give is "standard torque".

Q: Can you tell me which wires attach to which post i.e., on the smaller post on the front, does one go to a positive current switch and the other to a negative and if so which is which? Also on the power transfer lugs, is one preferred as the input and another as the output or are they interchangeable?

Either of the large studs can receive or transmit 100 amps; i.e., they are interchangeable; one small lug is for switched positive signal and the other small post goes to ground and as with the large lugs, the posts are interchangeable; i.e., current can be directed in either direction.

Q: Can I use a continuous duty selinoid for a starter relay?

Per the supplier: No, they cannot be interchanged or they will fail.

Q: Is this Lamar Solenoid 12V (X61-0028) suitable to be mounted to a metal battery box?

Per the supplier: Yes, it is externally grounded.

Q: Is there a recommended mounting position for this 12v Lamar solenoid? In other words, is there a top or bottom?

Per the supplier: Can be mounted in any position. Most are installed with the hat on top.

Q: Can this relay be used on certified aircraft?

No, the Lamar 12V solenoid (07-01875) is not FAA PMA approved for installation with a log book entry only. It can be installed in a certified aircraft with a 337 field approval.

Q: What is the weight of the LAMAR SOLENOID 12 VOLT CONTINUOUS (X61-0028)?

Approx 0.95 lbs.

Q: What size ring terminals are used for the large and small posts?

The front two terminal posts are 10-32 UNF-2A and the larger side posts are 55/16-24 UNF-2A terminal posts.

Q: I presume continuous means that the solenoid can be used as an isolator for the battery. It would be on the entire time the aircraft is running?

Yes continuous would be a Master/battery solenoid.

Q: What is the normal operating temperature of the unit, it feel hot when active, cant hold hand on it for very long.

The manufacturer does not have a specific temp range but it is normal for them to get quite hot during use.
