Thanks Bob, I expect you're right. I may set up a simple bench-top experiment just to see how much each gauge under reads with the bulb in a pot of boiling water.

If wired in parallel, can one oil temperature resistance bulb supply oil temperature information to two separate instruments? I can't fathom why it wouldn't if all it basically is is a resistor... T ...

In my former life as an airline pilot, the policy on reseting CB's in flight was "If it is absolutely needed for flight (gear, etc), one reset was allowed. If it was not needed for flight (galle ...

Thanks Bob. The MS31xx type of plug was what I had in mind. I hadn't thought of grounding the switch through the shields but that makes sense. Thanks again.

If you ran the P leads through the firewall using an old fashioned Cannon plug, could you use a three pin plug and run both shields through one pin with no noise consequences, or would a separate pin ...

Fortunately at the moment nothing is hooked up and I have no amp installed. The radios (Garmin SL40 transceiver, GTX 327 txdr with Ameri-king encoder, Aera 500 GPS) are mounted, as are the headphone ...

When adding the GPS (stereo) audio, do the GPS audio outputs wire directly to the headset jacks in parallel with the comm ouput wires? And when you're using stereo headphone jacks do you just wire th ...

Thanks Bob, I really appreciate the advice and help.

I'm restoring a Stearman. The headset & mic jacks and intercom PTT for
the front seat all reside on the front instrument panel. The radi ...

In the interests of killing two birds with one stone, could I run my headset, mic jack, and PTT wires in the same 3/8" dia aluminum conduit as my mags' P lead wires without screwing up my audio s ...

Ok - thanks. That was the way I understood it.

Thanks Bob. Would there be any value in tying the avionics ground bus directly to the battery instead of to the main ground bus? (Putting the two ground buses in parallel instead of in series).

In a mixed construction airplane (steel tube fuselage, wooden wings, aluminum structure flight controls, everything fabric covered) what would the down side be in not having everything electrically bo ...

If there's anything better I'd like to see it.

I'm in the process of mating up a PS Engineering PMA4000 TSO Audio Panel (slick little unit!) with a King KX170B, and a Garmin GNC250XL, but I'm having some trouble identifying the appropriate pins on ...

Can anyone confirm for me what pins on the KX170B and 250XL are picked up by pins 19, 7, 22, 21, 9, 18, 6, 24, 23, and 10 from the PMA4000? The King radio will be Com 1 and the Garmin Com 2. The 20t ...

Thanks, Ron - that's EXACTLY the tool I was looking for. Just ordered one from him!

Dan

Thanks Peter - I'll look into that.

Stein Air used to sell a crimping/swaging tool for #2, 4, and 6 AWG terminals, product ID was TERMTOOL. I guess they're no longer able to get them. If someone is done with theirs and would like to s ...

Thanks guys. It's steadily getting clearer!
