Swede Lobster H2 is off the scale
Default Re: Folding mirrors

I have an -03 H2. The left mirror was replaced under warranty two years ago by the previous owner. Some time ago I read a thread here about that it is no good to fold the mirrors manually as it quickly wears out the mechanics.
Then I tried to fold with the electronics and the right mirror didn't move.
Back to this forum and did a search and found an excellent description with pictures from someone that had repaired his mirror.
I experienced exactly the same things as he wrote about. The folding motor and electronics were rusted. On mine the gear mechanism was also very hard to rotate, but I got it back in shape by spraying it with Teflon spray and finally adding some Lithium grease. For the electronics I cleaned off the rust and put electric contact spray on the connector surfaces. Then covering it with vaseline (isolates from water) and drilled drain holes in the bottom. If there had been drain holes from the beginning this problem never would have happened.
I also found out that it actually is possible to accidentally reassemble the small motor in a 90 degree angle. I did this mistake and couldn't assemble the gearbox to the mirror. It took a while to figure out what had happened.. thought I had a brain reset. The other thing maybe worth knowing is that the electronics on top of the motor is an overload circuit that shuts off the current when it is too high for more than about a second.
The folding function can be tested with 12V connected to the yellow and blue wire (next to a white wire) in the blue connector. When the mirror reaches a mechanical endstop the overload circuit shuts off the power. Then the polarity can be reversed and the mirror will run in the other direction until it reaches the endstop.
While having it apart I looked at the mechanics that makes it possible to fold it manually and can say that I now understand why manual folding should be avoided.
