Hi Guys



We intend to mount a Garmin Aera660 semi potable GPS into our panel using an AirGizmo mount, so far so good, with the wiring pack comes a 'cigar socket' power plug, is it OK to cut this off and connect to the aircraft bus, or does the cigar plug actually have a voltage reduction circuit inside.

   Appendix D of the users manual describes

   this item:



 [img]cid:.0[/img]



   A 'bare' wire interface between the Aera660 and

   ship's systems. Also, the manual speaks to an

   internal, 3A fuse in the cigar-lighter plug.

   This is a common connector to many automotive

   add-ons. The fuse installation takes up a substantial

   volume of the connector shell . . . it seems

   very unlikely that it contains additional

   electronics . . . a disassembly would confirm.

Hi Bob



I've managed to get hold of a Garmin GPS lead, and the plug that goes into the unit has four pins, two are dormant, the other two are 12v + & -, the cigar plug once dismantled has indeed a glass fuse link, so all good for 12v fused to the aircraft bus.



Which does raise one other question, the fuse looks like 1/4amp, how do I fuse this (and other items like 'steam gauge lighting') which have only light gauge wires, the smallest fuse available for the bus is 1amp

John,



I'm not sure where you live, but you should be able to go to an electronics

store and find that fuse there.  When I was still at the local airport as

manager, we installed an AWOS, and the phone line to it was fused with a

1/10 amp fuse.  When we installed it to protect an ISI board ($300) we no

longer blew the board at evey thunderstorm.  That 1/10 amp fuse was only $2,

and much easier to replace.
