Igniton coils

[Fredrik Skog]

Hi!

Can someone please enlighten me in how to decide how much current I can
put into my coil. I have a coil from a Alfa Romeo 155 and it is of the
waste-spark type. It has a primary resistance of 0.9 ohms.
I think I have wasted one coil already due to my lack of knowledge. I just
pumped 12 volts into it and it sparked a few times but then went dead.
I have one more but I don't want to kill this one too.
Do I have to know what voltage the Alfa puts into the coil to know this or
can I calculate/guess what it is in some way?

Any help is greatly appreciated.

Thanx!
