I think what you are asking all depends on what flight instruments are on board. If you have a radio and transponder, that isn't a good practice as you are making the Battery the primary power source with an alternator backup. They may not draw much, but the surges associated with kicking in an alternator can't be good on the electronics. All would depend on if there were some kind of built in surge suppression which I seriously doubt. Then again, if you are using navigational lights and a beacon, along with whatever else, you are definitely drawing on that battery power. Like anything else, a battery backs up the alternator and vise versa creating some redundancy. You are eliminating a back up by switching it out. As far as FAA acceptance of that type of mod, they might look at the fact that turning it back on can easily be forgotten. Not to mention the increase of yet another task during your climb out if something were to go wrong. Just my humble opinion!

She is a '46 C w/a C90. The fellow in Texas who sold her to the guy I bought her from had all the work done but never turned in the paperwork for the conversion, although I understand he flew her as such....I have the paperwork, so that will get done. Now, long story done....he installed a switch cutting out the alternator after she was warmed up and ready for TO...supposedly adding 5-6 HP to the TO power ( that could work ), and then he would turn the switch back on at altitude. Is this a legal mod? Should I remove it during the restoration or can I cover it with a STC or 337? Any advice is welcome..............Thanks, Cliff --------------------------------- to unsubscribe send mailto:[EMAIL PROTECTED] ____________________________________________________________ T O P I C A -- Learn More.
