On an old vehicle with no ECU, but with Hall Effect "points replacement" device:
I want to count ignition pulses, and I gather a method is to use an inductive or capactive sensor with a spark plug lead.
However, I'm wondering if I could use the low tension wire at the ignition coil terminal?
I just think it would be neater.
Assuming it's possible, any suggestions for some filtering circuitry?
The project is to be a "starter motor inhibit", to prevent it from trying to engage once the engine is already running.
Thanks folks,
Old Newbie
