1978 70hp won't start/no power

[curly206]

1978 70 hp evinrude. I get 12vdc to terminal block and don't know where to check next. I can't find voltage after terminal block. Does 12vdc go from red wire OF terminal block to rectifier to stator to trigger to cdi to coils? All i know is there is 12cd to terminal block and no fire to coils on cdi. I need help in between.<br /> thanks for any help!

On the '78 all you get from the battery is the power to drive your starter and starter solenoid and to activate the choke solenoid.<br /><br />The rest of the power comes from the running motor. <br /><br />You need a good, fully charged battery to start the motor.

I have a fully charged battery. I checked the rectifier and it is good. After i turn the motor over and the flywheel is spinning, where does the fire come from? The stator or trigger then to the cdi and what should the readings be with a volt/ohm meter?
