Yes on the GAD 29B, a GNC355 is providing data for the HSI. I am not yet sure where all of the other equipment is installed.

Yes I do have OAT, good observation

G5s are good. Old vacuum gauges we’re getting tired

No auto pilot so no FD. Still using PC wing leveler, The HSI is tied to a GNC355. Thanks for the suggestion on dual cue.

My attitude and attitude indicator are both good now. Thought I would share.

Make sure p-leads have not been reversed between mags. If they have been reversed you may be chasing the problem on the wrong mag. Just a thought

I mentioned in a previous thread that I had a GNC 355 GPS/Com Installed and had a request for pictures.

The vacuum pressure was running at almost 6 with full power and was staying high when throttle was pulled back to 1700 rpm

I will post some pics of the gnc 355 when I get back to the plane Hopefully before the end of next week

Carusoam you nailed the ammeter. I found a wire broken on the end of the fuse holder. Problem solved it will be a couple of weeks before I can chase the high vacuum. Any recommendations on where and for what I should be looking. I really appreciate the assistance. Dennis

Thanks will give those a look

1970 m20c. Went to fly today to play with my new garmin gnc355. Three things amp meter not moving vacuum pressure was high and attitude indicator was a little slow spooling up. With the help of my a&up friend we looked for the cause of issue. 1. Amp gauge a. Amp gauge has about 2.3 ohms of resistance and does move with external source of voltage. b. Alternator and regulator are working confirmed with volt gauge plugged into cigarette lighter c. One wire to the gauge does indicate battery voltage. Other wire on gauge does not indicate voltage. . d. I still need to verify continuity on the second wire, I am Assuming it goes back to the regulator but have not yet consulted the wiring diagram in my manual Thoughts? 2. Vacuum gauge a. Hooked on my mighty vac and pulled 5in and gauge indicated same b visually inspected vacuum lines and all look good with no kinks Thought? 3. Attitude indicator Guessing cool morning and thick grease appreciate any thoughts, direction, other things to check Dennis

on my 1970 C you can see the duct attached to back of alternator. The larger Scat is used to make Coffee when not being used for cabin heat.

I just had my Muffler and Risers overhauled by AWI. The turn around was quick, they received my exhaust on a Wednesday and shipped it back the following Monday. All for a price less than worst case scenario quoted. Very pleased with their service.

Sweet -- May you have many happy hours. Dennis
