It may well be that the ICU test did not work the first time because the brown wire was not grounded well enough.
In the interim I made and extra ground wire that goes fro the same coil bracket to the battery - post.
The ICU test good now.
That leaves me with one last thing to replace, the hall sensor (bean can)...
Today I put in the spankon' new flexy board in the aguges and tested the bulbs.
I even replace the neutral switch.
There is a fresh ground to the battery and cable to the starter, plus an extra ground to the batery to the coil bracket.
All good.
The lights in the gauges and dash work, neutral lights works.
ICU checked good.
Only thing left is that bean can as far as spark goes.
