No high frequent sound from the CDI unit...
 

Yesterday I had the blowerfan and case on my -74 powdercoated, but today when finished assemblied and ready for start up, there is no high frequent sound from the CDI unit and no or very little voltage to the fuel pump.

I do not see how my painwork is related to the powerloss, but I then again can it be some ground issues. I have ground on the fancase through the coil screws attachment.

'74 CDI grounds through the shield wire on the CDI case. The +12V is the centre pin of the 3 pin plug. Check for 12V across these two points with a test bulb.

Do get +12V in the centre pin.

By the way, I do hear the frequent sound from the CDI unit, but only if I stick my hear very close. Normaly the sound is very high.

And why do I suddenly get no voltage to the fuel pump...?

By case, you meant the fan housing ? Check the ground connections around the coil plate.

You’re ground, shielded wire outside
If the wire inside is breaking down the volts to the points is crossing to the shielded wire.
Use 3 alagator clip wires and replace the wires in the harness

Bruce,

Have you considered writing a book? Might be worth while.

Thanks, Gordon
