So if I drive my car 20 to 30 minutes the ten amp ccci fuse blows. Can anyone show me a schematic for this circuit or give me a little information about it? Have any of you had a problem like this before? I did just put a new ignition coil on it it fixed my running problem but now this is happening. I would imagine it's related because I don't get spark when if happens. But I don't have a schematic with me right now to see what the fuse protects.
