Hi All,
Checks performed with a 150w consumer/load shows 13.2v on my multimeter feed at the rectifier and 12.9v on the cockpit instrumentation. Getting 15VAC at idle and all other checks as per HMM are right in the middle of the tolerances. Right on the low end of the scale I know, but the new battery will not charge and the fuel pump circuit breaker seems to keep popping when going for test flights. Technically speaking the stator/generator is in good health still yeah?...
Switch to one fuel pump only when in flight - the circuit breaker will pop here after a while of flying, then there is the radio, transponder, strobes, motorised constant speed propeller and some odd instruments that are being powered.
The plane has been shipped over from America and meant to have being flying okay with all of this stuff going. There is no auxiliary generator fitted, just the stock internal. Good for 15 amps continuous right?
150w load divided 12v = 12.5Amps draw at test
Guess I need to put everything on at once and establish the total Amp draw. Does it sound like a case of simply too much out and not enough going back in do you think?
Any thoughts and advice welcome as ever please folks. Thanks in advance...
