tach <br /><br /> picked up a tach for our '61 V4....there is a grey wire that goes to the points-mag. or battery, ignition....so the grey wire can go to anyone of these connection points or is the points the only or best place to connect. <br />The black wire goes to ground...then there are 4 connection points on the back also...C, 2, 3, 4....and says connect shorting terminals as follows: for the number of pulses per revolution generated by the above connected point contact ...meaning the grey wire I guess....since this is a V4 I would use the 4?? and connect it to what...and what is the C terminal for? <br /><br />I have the grey wire in the ignition harness and a ground from the ignition light....thanks for any help.... the pic is a little small...
<br /><br />the grey wire will got to one of the M terminals on the ignition swith, the black ot goround. and then set the jumpers accordingly.
