Reply to "Ballast Resistor"

I have had two ballast resistors fail like that. Inside the ceramic shell is a core that the resistance wire is wrapped around. It breaks and the terminal gets wobbly. In neither case did the conductor actually break and strand me, but only because I noticed it early I think.

I'm not sure why they do this. Maybe the duraspark module pushes too much current through the ballast resistor to the coil?

I carry a spare now.
