Are you increasing engine rpm above idle during the checks? Some alternators/ pulley
size combinations will not get above battery voltage until the engine speed
is higher.
Good luck and happy holidays to all!

Merry Christmas to all
Its now the time to make the configuration of the G3X in my RV-10 with IO-540.
Can those who already did it, and tested it flying, please send me their configuration
data.
Thanks in advance

There usually isn't much to those things, you need big wire/current from
it(#6 probably) and small wire/current to it(#18 probably).
Your alternator needs up to 5 amps on the field, you could test that you've
got sufficient current available by briefly putting a 50 watt halogen bulb
on the field at the alternator end and seeing if it lights up.

Grumpy
My suggestion would be to pull the alternator and have a rewind shop check it out.
They have the test kit that will remove any doubt as to its status.
Only then would I start troubleshooting other things - unless it is super obvious
like a broken field wire.
I would not take any chances on the alternator as it could lead to expensive repairs
- I had an IR alternator go south and and cause all kinds of havoc to my
avionics a couple of years ago.
In my opinion, it is not worth the risk to try and troubleshoot it while connected
to your electro magic gizmos.

Bill, I think you hit the nail on the head.
We traced down today that the 12v isn=99t carrying any amps to the
alternator, so have to look back at connections, etc, to see if I have a
bad crimp or a pinched wire (ugh!)
My ace A&P and an electrician friend helped me get to that point, and
you don=99t have to use the light bulb. Put the voltmeter on the
connector with it plugged into the alternator and see what the volts
do..went to less than 1v. Disconnect from the alternator and
reads a solid 12v.so I was getting voltage, no amps through the
wire.
Thanks - grumpy

| Subject: | Alternator will not put out current |
I had an alternator put out too much volts last year. Fried the LED trim
indicators and cost $500 each to repair the 2 Dynon screens. Autopilot
never worked quite right afterward and finally had to send it in for a
fix. There are 2 external ways to prevent overvoltage. One is a crowbar
device across the field circuit breaker to short it and make it pop on
overvoltage. The other is a circuit that looks at voltage and opens a
contactor in the alternator output on overvoltage. I put in both.
