Re: Essential Bus breaker tripping issue

Getting a little bit frustrated here... My mechanic couldn't find anything wrong with the electrical system. Again! That was now the third time in the shop for the same issues and "nothing wrong" with the plane. I asked him if he can replace the brushes and he said he would have to pull the alternat...

Re: Essential Bus breaker tripping issue

I believe it is the still the OEM alternator. I will give the shop a call and let them know to check that first. They think it might be a corroded wire somewhere but I don't really believe that.

Re: Essential Bus breaker tripping issue

I brought the plane back in the shop this morning and I hope the mechanic listens this time. It has been in the shop twice because of these issues and they could never find anything wrong with it. I'll keep you guys posted what they find. Or at least I hope they find....

Re: Essential Bus breaker tripping issue

I did not get any alternator alerts on the ground or during flight. Also charging Amp is pretty constant during flight. The issues only come up when I try to restart. If I hook up a GPU the engine fires right up.

Re: Essential Bus breaker tripping issue

Antoine I will try to find a battery I can borrow but I am still curious about the Voltage overview. If the battery is bad I would expect the voltage to go down steadily but the graph shows it jumping all over the place. I am wondering if the alternator or regulator is not working properly or if it ...

Re: Essential Bus breaker tripping issue

Good news I had the plane checked by a mechanic twice and they could not find any issues and the essential bus stopped tripping. Bad news I still have issues with my Voltage and Hot/Warm Start of my engine. I have a new Batteryminder installed and I am now always charging the battery. They Batterymi...
