There have been issues with Plane Power. 1 - Look at the voltage regulator (ACU). 2 - Check the resistance of the FIELD. 3 - Check the resistance of the wires going to the field. 4 - If all those check out the next thing is to verify the voltage coming out of the ACU. If it is LOW the output of the ALT will be low. You can FORCE it high by applying a remote Field Voltage. This will increase the Output Voltage. 5 - I'm sure you know this by now - The ALT output should be 13.8 to 14.2 some say 14.5. Well, the 0.3 V delta is extreamly minor. What is important is the Minimum 13.8 VDC. 6 - Have you checked the accuracy of the meter you are using? 7 - NOISE - Plane Power has had many reports of NOISE. The easiest thing to do is put a nice big Electrolytic Capacitor across the output of the ALT. I find a 25,000 uF @ 16 VDC works. You can go higher in both uF & VDC. In this case Bigger Is Better. Hope this helps, Barry On Sat, Apr 7, 2018 at 8:15 PM, David Duperron wrote: > I completed my RV-10 in July of 2015.

From: "rsmith52" I plan on using Figure Z12 as the architecture for wiring my Bearhawk. In the process of converting the diagram to physical location for equipment and wire runs I noticed that the only wire that doesn't seem to have any protection, or is kept very short, is the Battery Master switch wire, 22ga running from the battery contactor to the switch? I could not find a discussion of this doing a search.

I could not find a discussion of this doing a search. There is no failure mode that puts that wire at risk. "Pull to ground" control lines on contactors have never benefited from protection.

Can you point me to any discussions/narratives on PlainPower products? Last I looked over their product line, they were pretty much invested in modifying stock automotive to accept external control and ov protection while retaining the built in regulator. Aside from manufacturing errors, their business model seems to offer little performance risk. I'd be interested to know what kinds of problems builders are having unique to Plane Power. Thanks.

He told me a story about an incident back before anyone knew the SR-71 existed. An airliner on a regular flight had a lot of panicked passengers when a huge black UFO appeared behind one wing. Upon landing, everyone on the plane was escorted into a room and 'read the riot act'; forced to swear out nondisclosure agreements that they would never reveal that they had seen anything. An SR-71 had descended for refueling, and joined up on the airliner instead of the tanker that was nearby..... On 4/9/2018 2:37 PM, Harley Dixon wrote: > Wow!
