Good product

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.

Good quality. Nice clear installation instructions. Works like a charm in my Grumman Tiger

Please check how hot these relays get. They can certainly get hot enough to start a fire on board your airplane. I asked numerous A&Ps and none of them can give me an answer of how warm or hot these relays can get that does not create a fire hazard. My relay was installed properly and I just happened to notice that it was hot to the touch. Good Luck.
