Surfgate issue - Axis A20 2016 have checked other threads

[BH78]

Hi, need some help please. My RH surf gate extended today and would not retract.

I was able to get it to retract by placeing direct power and earth to the actuator.

When calibrating the surfgate the LHS made noise, and the RHS did not.

When placing in service mode, both actuators extended however only the LHS retracted.

Ideas please? I'm leaning towards a faulty actuator

It is not likely that the actuator is the problem if you were able to get the suspect actuator to retract using direct voltage and ground.  It is more likely that there is a problem with the relay pack or one of the connections between the relay pack and the actuator.

Thanks, I followed the harness up to the medallion module - I couldn't see a relay back between the actuator and box?

OK, checked all of the connections and sprayed them with Inox. All looked good. Relay's given a tap. Same result.

Is there a seperate relay for each side? If yes, try swapping and see if the problem follows the relay. Full disclosure, I am a skier, no NOTHING about this surf stuff!!

Nope one relay pack - thanks though

You could cut the zip ties in the harness wiring and swap the port actuator harness connectors to the starboard actuator, and vice versa, for a quick test.  Using the surf gate service function and a volt meter, you could track down if the voltage and ground polarity is being switched at each connection from the relay box to the actuator like it should.

FYI, there are actually two relays for each actuator.  They are all just potted into one box.  Look online for reversing polarity motor relay circuits, and you should get a good idea of how they work.

I don't think I have any good photos of the 2016 Axis relay and IO module boxes, but here are some from a 2016 Malibu.

Thanks, I did see that - just seeing if my dealer in Australia can get one
