RVI to RVC 3 powering up the board

NOTE, later boards should have the calibration signal connected to the calibration input (nearest the chip) This is No 3 in a series of short videos describing how to fit the Spiyda Design Tachometer conversion board This one shows power and input signal being applied to the board. It also shows how to recognise when the movement is connected the wrong way rouns and how to correct it. Note.. -: if the movement tries to go the wrong way...swap the black and red wires that go to the movement only... DO NOT SWAP THE POWER WIRES!!!! Later versions of the board have more input connections, please refer to the printed instructions Other videos are RVI to RVC 1 dismantling the tacho RVI to RVC 2 fitting the circuit board RVI to RVC 3 powering up the board RVI to RVC 4 calibrating RVI to RVC 5 alternative connections
