Low Generator AC output
in 912 / 914 Technical Questions
12 years ago
Hi!
A friend has problem with the 914 charging system.
Some hours ago he mentioned a lower than normal charging voltage and today the red light was burning.
I checked the regulator output on B+ and got only the battery voltage.
I checked the yellow to yellow wires of the generator and got 0,9 OHM. A little bit outside of the range from the manual that says 0,1 - 0.8 Ohm. It is not a calibrated OHM meter!!!
Yellow to Ground infinitive.
The AC voltage output is at idle low. 11 V instead of 18-20 V
At 2000 RPM the Voltage is 15 V
At 4000 RPM 30 V
The regulator ground to ground is OK.
Do you have an idea why the Generator AC output is so low at idle and 2000 RPM
Thanks in advance
