Maule newbie questions
Hello all, Ive been lurking this site for a while and thought it was time to start participating.
I have a few hours in a friends M5 210 and have some questions about the airplane.
On the last oil change I noticed that the label on the alternator read 28V. The FoMco regulator is 12V as well as the rest of the system including the single battery. I didn't have a voltmeter with me at the time so I didn't get a chance to get an actual voltage reading. Is It common to have the electrical system configured in this way?

Hmmm, thats a good point.
The electrical system seems to work ok except for cold start issues and noise in the comm.
I am guessing that rewiring could be accomplished through replacing the internal regulator. If thats true the rated amperage (60) will change as well. I will have to do some research on that.
The reason that I was looking at it was to determine if we could add charging points in the cockpit. The cig lighter port will not keep an iPad charged.

Chris in Miliwakee had an issue with his Stratus Power not powering his iPad too. He found that the panel grounds were bad. That may be why your cig lighter port isn’t getting enough voltage/amperage too. Check the panel grounds and make sure they’re good tight and clean with no voltage drops.
Also make sure the USB charger you’re using can put out over 2.1 amps.
iPads take a lot of power to keep charged while running something like Foreflight on max brightness.
At Oshkosh this year Sportys was selling a USB port for cig lighters that has a built in Voltmeter for a great price. I bought one and found a problem with my brothers 172 port the first time I used it.

doubleh, for the cold starts try turning your fuel boost pump on, push the throttle in until you get to ~6 on the fuel flow needle and then crank. My 210 starts within 2 revolutions. Of course be ready for a quick throttle pull when it fires.. For hot starts, I rarely have to use the pump.

Truth. I had to run the ground to the airframe ground which is on the firewall tubes. It worked after that. That was the iPad Pro 9.8", though. It has higher current requirements (which the Stratus Power can provide 2.5A). My iPad Mini 4 and iPhone were never problems.gdflys wrote:Chris in Miliwakee had an issue with his Stratus Power not powering his iPad too. He found that the panel grounds were bad.

Thanks for all the information! Atleast I have a place to start.
I will check the voltage at the alternator and at the battery first, then check and clean the grounds. Hopefully that will clean up the lack of instrument light, and the noise in the comm as well.
We use a usb rated for 2.1amps. I don't know if it actually produces that or not though. I will check out Stratus.
Thanks Rob for the start procedure. Just so I am clear do you leave the boost pump on or turn it off after it gets to ~6?
