I verified that the solder is not bridging any adjacent pads and there is continuity at both ends of the wires.
With the wires soldered to the original board, but without the spengler link board connected, both wands function perfectly.
But when I connect the spengler link board, the wands react differently:
-Static Orange LED starts blinking immediately after plugging in the 8 pin connector to the link board.
-None of the toggle switches have any effect.
-If I hold down the wand ear button, the orange LED stops blinking and all the toggle switches all start working correctly. But when I release the wand ear button the orange LED blinks again and the wand stops working.
-Static Orange LED turns solid on immediately after plugging in the 8 pin connector to the link board. None of the toggle switches have any effect.
-If I hold down the wand ear button, the orange LED turns off and I can turn on the first power toggle switch and the wand works fine. I can release the wand ear switch and the wand remains on.
-I can toggle the vent switch and the lights turn on.
-I can toggle the activate switch and the vibrating motor turns on.
-Hitting the Intensify button shuts the wand off (with the sound effects). But if I hold down the wand ear button first and then hit the intensity button, it continues to work like normal. I can release the wand ear button and press it again to toggle between the various modes.
On both wands, the voltage measures 3.6V between pins 1 and 3 on DB1 of the link board. The voltage measures 4.1V between the red and black wires on the original board where I soldered it. The feedback LED on the link board has never turned on after installing both jumpers to the ON positions.
Do you have any suggestions what I should check next?
