A friend is having a charging issue with his 1977 PA28-161
A recent case is like this:
After some minutes of flying, the amp meter drops to 0 and the voltage drops from 14.2 to 12.
Needless to say, this drains the battery.
After recharging the battery on ground, everything looks normal.
The Piper is started, and during run up, take of and some 3 minutes of flying everything is normal. Amp meter is in 20 amps, and voltage is 14.2 before it drops back to 0 amp and 12v.
We switched off all electric equipment and landed.
Half an hour later we started up again, and everything is normal. 14,2 volt and 20-30 amps depending of how much equipment was turned on.
We were running the engine for approx. 10 min. on ground and could not reproduce the problem.
We have been looking for loose cables and pore grounding but every connections seems ok.
Does anyone have any idea?
