Hi, fellow subbers.
I've got a Graupner "NavyV40R" (Gr 2875) motor regulator w. BEC (Battery Elimination Circuit), with a 5.5 volt output through the BEC. I've also got too "Mini Switches 40" (Gr 3294) from Graupner. They are supposed to work as remote controlled switches, and simply switch either +12V or GND (Ground) through their relay contacts, to my electronics board controlling the dive valves, but they're rated 7.2 - 14 volts. That's where I get worried...
Should I disconnect the red supply wire in the 3-wire connector that goes into my receiver, and then let the mini switches get their supply from the 12 volt that they switch, while leaving the orange signal wire and the brown ground wire, or should I shoot the engineer?
I seam to recall that signals does not like it when traveling between two units with non-matching supply voltages...
REALLY hope you guys has the wise answer to this one... surely someone before me has had this problem with non-matching BEC voltages?
Yours Sincerely, Robert Holsting, Denmark
