New Ammeter needed

[TonyPynes]

My 1970 M20F is going to need a new Ammeter gauge. I have the original strip of gauges.

Are these available anywhere? if possible I would like to replace it and move to better gauges later.

 

thoughts?

I'd look into EI's all in one ammeter and voltmeter if you have the panel space.

You could check with Air Parts of Lock Haven about having them repair it, if you're sure the problem is in the meter (as opposed to the shunt, or the wiring to/from the shunt, etc.).

Do yourself a favor, and get a digital one. The factory ones are worthless. My old one wouldn't even budge off of zero unless there was at least 20 amps of draw. To me, that's worthless.

i cant believe you got a mechanic to sign that one off.  Its not an aircraft, or even automotive, part.

My former E model Mooney had a load meter to show electrical current and it was almost worthless. I found an inexpensive digital voltmeter (only about 1.5 inches long) that worked perfectly. It only required hooking up two wires and easy to install. I made a small angle bracket and mounted the meter to it. Then pushed it under a piece of metal near the 6 pack instrument cluster.

Yes, inspected and signed off by an A&P / IA.   And they are all aircraft parts.  I thought a TSO, PMA, or some other approved data was required to install parts into an aircraft.  So how did you do it?

You can get different sensors to provide different information so you can set it up for many types of FWF's. I have volts, amps, 4 egt, 4 cht, carb temp, and oil temp. I bought the basic instrument first and added a fw probes once the checking account rebounded, hen bought a couple more. I was amazed at how little information the old OEM gauges provide.

Respectfully.... you replaced a certified function (reading current) with an indicator that reads voltage.  The indicator you chose has no FAA pedigree, no PMA, no TSO, you put it in a public forum for the whole world to see and you get annoyed when someone (who is one of the more knowledge people on this board) asks you a question?  Byron is trying to tell you something.  I would listen to the message.

I know that voltemter didnt replacd the certified instrument.    The voltmeter is in addition to the Ammeter (which sucks and provides no useful informartion)  I think rules change too slowly for technology. For example, I have a friend with an RV-8.  3 GPS's. autopilot.  dual EFIS.  you name it.  My 201 has a Mitchell atttude indicator and DG, and a Century IIB autopilot.  I cannot install the Dynon D10A EFIS in my certified aircraft even if I have all the other required instruments. The difference between what I have ands that is the difference between the horse and buggy and the space shuttle.

To be fair, even so, certified aircraft are a hell of a lot safer than experimentals. The statistics bear that out.SO i digress while grumbling.

I have a plug in 12V voltmeter that goes in a cigarette lighter I fly with. here  The question  have for Skybrd is how did he wire it to ther ship's electrical system and permanently mount it without approved data.  That is the catch-all.  Thats the stuff inspectors love to see.
