Spike the PCM and have to by a new one. Spike the generator and have to buy a new one. Possibly repeat this for every Class2 module and you'll get the idea. Some EBCM's are $1000. What happens when loaded contacts are separated? Lightening...that's what. It's called points. Points used to be in distributors to fire the spark plugs. It might not happen every time but why take the risk? Besides, the ECM, etc. needs constant power supply to operate properly...and most alternators are PCM controlled.
