Went to the Houston fly-in in the RV-4, everything normal on the way up. After taking off at Sport Flyers I noticed I was not charging. O.K. turn off everything, radios, etc. and get the discharge rate down to 2 amps. I have one mag and P-mag plenty of battery to last hour flight home, plenty of little airports on the way to bail out. About 20 minutes in I start to get charge again. About 10 minutes from home I start to get big spikes in charging on and off.
What's going on. I didn't build the RV-4 so I'm not familiar with the charging system. What is the normal alternator? Does it have seperate voltage regulator? I'm going to start digging through paperwork to start to sort this out.
