    TLP3 Test Point is the GROUND for the low Voltage coils? and the TLP1 FET Test Point is the GROUND for the High Voltage coils?

      From pinwiki....TPL1 FET will apply 3.4v to the gate of the MOSFET transistor thus switching it on. TIP TPL3 serves the same purpose as TPL1 except for the TIP transistors on the driver board Q17-Q32.
