Still no luck with the sparc. I dont get this.
I cooked one coil, 12V batt on coil =30 min before coil-boil.

How can VEMS charge- and controll discharge, controlling only the coil negative (pin 36:35)
I tried measuring the amps, while testing the circut in vemstune. The current was constand aprox 300MA(
![Huh ???](http://www.vemssupport.com/forum/Smileys/default/huh.gif)
), and actually fell a litle when pressing "test". At least something hapend. Diffenrent types of coils? Bosh "transistor based" coil, is says in german.
Shuld i use 1 or 4 ign. outputs?
