Have issue with 2 tach's not working and after testing all connections @ tach and Tach-adapt I'am left with the black/purple wire from the CDI (3 pin) to test.
My later tach (low voltage ) will cause the Tach-adapt LED to come on with the ignition on and the needle bounces when cranking however with engine running ...nothing. My early tach (high voltage) isn't working and this is the one I will convert to Ashlock-tech circuit board replacement but need to know the pulse from CDI is working. TIA,cheers. |
