From what I understand, most one wire alternators have a built in switch so you can hook up a charger to the battery, jump start etc. This type does not have an internal switch. so when I hit it full blast with the charger and turned the key to start the car the internal regulator fried. Jones Racing also gave me a small but high amp on/off switch to turn off the Alternator to charge the battery or jump start the car. Then you turn on the Alt again.
