I have a problem that I just can't figure out. I purchased an 8' mesh dish a while ago and have been setting it up. Got everything working this week and had it tracking 72W to 107W with a new HARL-3612+ actuator that I already had. I wanted to scan a little more of the arc and had bought a new HARL-3618 actuator that just came. After installing the HARL-3618 I was able to program two satellite locations and then it just stopped moving and the positioner gave ER2 code when trying to move either direction. Here is what I have done so far:
Checked dish for binding: OK
Reset diseqc positioner in case of limits problem: OK
Tighted down all connectors: OK
Checked all wires to actuator for continuity with meter: OK
Check for voltage at actuator when E/W buttons pressed: OK
Checked reed switch with meter: OK
Checked function of limit switches with meter: OK
Still nothing so, opened motor case:
Checked internal wires going to motor: OK
Checked motor brushes: OK
Added a bit of grease at each end of the motor shaft in case it was binding
After doing this and putting it back together it ran ok. I was able to extend it and retract it to the limits more than a dozen times. Thought great, that's got it. Put it back on dish, went inside and a short while later it quit again with ER2 on the positioner. ARRRGH!
After more tinkering I found out that if I loosened the two screws on the motor case, jiggled the armature assembly and retightened the screws it would run sometimes but not reliably. Has anyone ever got one of these that acted like this new? If so, were you able to track the problem down? The thing wants to run but something is just not letting it. One more thing, I hooked up the HARL-3612+ again and that runs with no problems so 99.9% sure it's something with the motor on the HARL-3618. Any ideas are appreciated!
