Kubota Ask R150 Manual Arts
• 185 Answers SOURCE: Hi, a word of caution, use a 9volt battery instead of 12v to check the rotating field winding. The 12volts from a car battery or battery charger can burn out windings in a generator. I would say that your avr is pooched. There are 4 leads that go back to the windings in the generator from the AVR. Two of these are connected to the power output and two go to a separate winding in the generator. This is the exciter winding and this supplies power to the avr for the rotating field.

The two to the power output are voltage reference only. If your generator has these exciter winding, you should check if you have voltage there with the 9 volts applied to the rotor. If you have voltage on the power output and not on the exciter, then the exciter is shot and your avr might not be. Try this first, if you could, could you take a picture of the windings at the back end of the generator, this will confirm for me what leads you have present. Posted on Feb 15, 2011. It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition.
The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation. You need to confirm and replace the specific stages or outputs.
If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias, maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers. Thank you for using Fixya Sep 09, 2011 .
A 'generic' turntable and a 'generic' HK AVR? 'PHONO' is the only designated connection on an audio device that is literal and exclusive. Nothing but PHONO will work right on it and old-school turntables would require it to preamplify the tiny current produced by a Phono cartridge. If your unit doesn't have a PHONO connection AND your TT doesn't have a self-contained preamp you will have to get a Phono Preamp to connect between the TT and any Line Level input, like Aux.
EBay always has some. Or your TT may have i Jun 16, 2011 . Hi, a word of caution, use a 9volt battery instead of 12v to check the rotating field winding. How To Install Sbsettings Without Cydia Ios.
