As the title sugests i bought a patrol and the po installed a hi6 unit to get rid of the points, only problem is tacho does not work anymore, i did some reseach and found that they make a tacho adapter but i need to know a few things.
Pulse sensing or current sensing tacho?
Pulse sensing tach: This type of tach has a wire that was originally connected to the COIL- terminal. Refer to Figure 1 to complete the installation for a pulse sensing tach.
Current sensing tach: This type of tach is connected between switched +12V from the ignition key and the wire that was originally connected to the COIL+ terminal.
And was the coil originally mounted on the inner guard behind the passenger headlight? And what colour is the tacho sensing wire that used to be connected to the coil?
Thanks guys
