greetings to all, referring to what is said in the course that we should know the dwell time of the coil we assemble, it has been impossible for me to find this information. If anyone could help me, it is a Magneti Marelli BAE850AK

Any chance this data sheet represent that coil model. The dwell time is very short (0.39 ms), but the current draw is high 21 A


If you can't find the information from documentation, or contacting the Magneti Marelli, then you could measure this yourself. I have used this procedure to determine coil dwell time requirements:


Thanks David for your help, I will see if I am able to understand this process.

Thank you very much!
