1 - When you say "The cable works fine and checked the connection", HOW did you check it and did you actually open up & check the F-connector joints because what seems "fine" with the very low currents (maybe just microAmps/milliAmps) in a DMM (multimeter) test may be relatively "high resistance" when you try to pass the 0.3 to 0.4A current that the Rx should be delivering when it tries to drive the motor and dish (taking the dish off reduces that current requirement considerably!) ?
That sort of "high resistance" can be caused by poor connections between the centre conductors, &/or the braided sheath and the outer bodies, of the F-Connectors (in which case, remake those connections!)
2 - Is the motor gearbox "too tight" because the backlash adjustment has been over-tightened?
3 - How old is the motor as the grease in the gearbox might have congealed over time? If so, clean out the old grease and replace it (a general purpose lithium-based grease works fine in my experience) &/or there is damage to the teeth on the gears which then jump/slip when heavily loaded by the motor AND dish?
4 - It's been mentioned before but have you managed to check the dish/motor combo by replacing the Rx with another (known working!) one? If replacement works then your Rx is itself faulty! Could simply be the internal connections are damaged or loose (several of us had that happen with one of the very small "fag packet" receivers - tightening &/or resoldering those connections fixed those problems)
Good suggestions. Long answer below and have tried to answer your points. I noticed the motor has slightly opened and 2 screws became loose. I took the motor off and tightened the screws of the motor. What I think has happened is that the dish brackets had got caught on the wire which I use to stabilise the pole. This must have happened whilst I was moving the dish in windy weather. The elevation of the motor slightly dropped hence cause the dish to get stuck when spinning. If you check my initial posts from 2 years ago you can see the setup and wires. The motor only moves if I remove the power from receiver for a couple of hours then reconnect. I can then move the dish only a couple of times before it gets stuck on the last satellite, the only thing which then works is go to 0 and dish will not move. I dont know if while the motor was slightly open in the rain, if water has gone inside or if the motor limits have stopped functioning. Is the limits within the motor mechanical or software based?
1. I have so far only checked the F connectors and cable for receiver and lnb. I have used new f connectors to the motor. Need to find the multimeter so I can check amp. The fact the motor was slightly open makes me think it’s something in the motor, rain water?
2. Do you mean when the motor is on pole or is that something within the motor. I haven’t opened the motor yet, only tightened 2 screws which became loose with wind.
3. Seems like I will need to open up the motor and check the teeth and gears, which I have tried to avoid. If I press the east/west button once the light turns orange. If I press it twice the light turns green but only moves less than a degree back to 0.
4. I might have another rx somewhere in the shed. I had Humax 5400 but that might not be much help.
Hope this is not to confusing in my reply.
Thanks for the help.
