Easy to install and works perfectly in our 1977 Grumman Tiger AA5b!
Product arrived as depicted/ priced for sale... regular shipping took 9 days (Mon thru Wed of following week) UPS requested clarification of my Ship : Town, State & Zip Code late 1st week for unknown reasons... which were noted as correct on original, intact Aircraft Spruce shipping label... this is the 1st apparent shipping delay in over 5 years of buying from your firm... will continue to do so...

Correct product sent timely.
perfect service !
Good product
Good quality. Nice clear installation instructions. Works like a charm in my Grumman Tiger
The solenoid gets warm but thats normal. Works great on my 56 172. I installed 16050-2 diode between the 2 small terminals to prevent damage to my avionics as well. For being such a basic solenoid, its pricey.
Regarding the heat generated comment on the first post, I would agree that the solenoid gets hot but I would not say dangerously so. One can hold ones finger on it for maybe a minute before it gets too hot to continue - the solenoid is not a bed warmer but neither is it a hotplate. At the same time, I would not be mounting the solenoid into some enclosed space where stuff is or could be packed up against it. Bolted to the side of a battery box or on a metal firewall or back in the rear tail area on metal would not be a concern. I presume that the coil inside generates the heat holding the contacts together and the amount of heat generated is independent of the continuous amps going thru the solenoid. I powered the solenoid with the plane in a heated hanger with just a radio and tpx powered, (2 amps), then plus the three nav lights, (+6 amps), and finally with the taxi light (+8 amps) on for an approximate total of 16 amps. A battery charger was connected to maintain power. As I said, it is no bed warmer, but neither is it a fire hazard as long as it is somewhat in the open. Also mounting the solenoid on something metal that would act as a heat sink has merit. Also buy a diode, (ACS 16050-2) and connect it across the small studs for most installs - it is like buying insurance for the electronics down steam of the solenoid of particular significance now that everyone is installing a G5 which is connected directly to the main buss rather than the avionics buss.
Q&A
We asked the manufacturer and they did not have any hard data available. The best answer we can give is "standard torque".
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.
Per the supplier: No, they cannot be interchanged or they will fail.
Per the supplier: Yes, it is externally grounded.
Per the supplier: Can be mounted in any position. Most are installed with the hat on top.
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.
Approx 0.95 lbs.
The front two terminal posts are 10-32 UNF-2A and the larger side posts are 55/16-24 UNF-2A terminal posts.
Yes continuous would be a Master/battery solenoid.
