the engine doesn't have power.The spark at all spark plugs is weak.If i leave the cable + of the coil(transformer) on the air it has 12V but if i conect it to the coil it falls to 4.7V .With the engine running it falls a little more about 0.5V. I took out the cable - of the coil (with the engine in stand-by) that comes from the distributor and the 4.7v remain.So is there anything else that can cause the problem apart from the coil?
