Hello:



For those with expertise  in electrical...This is the question.   if I turn

the  master switch on, and load any other

one, such  as landing lights, or strobes anything else...The Ammeter shows

charge,, positive..

( I know it should show discharge, no matter if is a little)  EVERYTHING WAS

FINE, SINCE FIRST FLIGHT...

This started stw days ago...

It does no matter if the engine is running or not....Everything else seems

to be fine...

What say you,,, First step, what to check etc..

Thanks



Bert

I don't know much regarding electrical except0 this.  You can't read amps when the alternator is not putting out0 power.  You mentioned this happens whether the engine is turning or  not.  I feel you have an instrument error.  What are you0 using?

Bert,



     This is really a stretch on my knowledge of electronics, but I have a

THEORY.  Depending on the location of your sensor, the draw to could

actually be read as a positive charge.  If you are attempting to read

positive current from the alternator, but your sensor is actually on the

battery side of your bus, then the flow to the positive pole (trons don't

really go from + to -), would be the same as if you were pushing the

electricity from your alternator.  This idea could be whacked, but you may

consider just changing the location of your amp sensor.



 



I guess I would check if it shows a greater positive current with the

alternator running.  Just out of curiosity, what ammeter are you using.  If

it's something like a Grand Rapids EIS then another possibility is the scale

and/or offset values got changed somehow.



 



If you don't get a useful response here, you may try posting it on the

Aeroelectric Matronics page.
