Hi there. What you are describing is typically an indication of a damaged ignition relay. Essentially, what’s happening is when you attach the battery terminals, power is bypassing the ignition relay and being sent directly to the starter relay. This is caused typically by a faulty ground wire connection or damage to other electrical components within the ignition relay. This can be a very complex issue to correctly diagnose, which is why you should have a professional mobile mechanic complete an electrical problem inspection.
