Navin is a Superstar!
I sent the REVO II board in, and received it back, fixed, along with the new, 2008 version of the PC Board for the SD45, in less than 5 working days.
The new PC Board for the SD45 has fixed the problem that the Chinese built into the old, 2001 board in the lighting circuits (I think). Anyway, it’s just a swap of board for board, it took me less than 30 minutes to make the fix, pretty much plug ‘n’ play. The only soldering involved was to reattach the speaker. Even I can do that.
I took a bunch of pics as the work progressed, and as soon as I can figure out how to get them off my phone, I’ll post them.
Navin wanted me to check the voltage at the motors under full speed, no load, to make sure that the motors were OK. They were. In checking the motors, I managed to get one of the axles misaligned, and that took me several frustrating hours to figure out. My fault, not Aristo’s or Navin’s.
It’s been said that one of the complaints about the REVO II is that the bell only gives a few dings, before shutting off. That’s true, however, if that button that activates the bell is held down, the bell will keep ringing. Once the button is released, the bell stops ringing after just a few more dings. Now, if they’d get the horn sorted, so that it would sound once for each press of the button.
