Dear subscribers,

 

I am using a bnc regulator on a TSIO550 with a teledyne alternator on my 4P.

 

I rewired the complete airplane so I can not completely exclude an installation error from my problem.

 

My symtoms:

I turn on the master switch (engine off) and my low volt light is continuously on. I add heavy electrical load and the light starts to flash. – Everything good so far.

 

I turn on my engine but the continous low volt light does not go off. When I add all the available electrical load that I have and let the engine idle at low rpm I get the flashing from the light – when I increase the rpm the flashing turns into a steady light again  (I also see 28V on my VM1000 and the amps that the alternator is feeding back)

 

Bnc checked my regulator and they told me it tested ok.

 

I connected my F1 terminal at the alternator to ground. The F2 terminal from the alternator is connected to the regulator.

 

If you would have any idea of what I am doing wrong here please let me know

 

Thanks

 

Ralf
