Right, capacitors do cause the tiny spark we sometimes notice. Charging of capacitors occurs very quickly which would result in a hard to measure draw afterwards..
What I was getting at is that if that spark is real noticeable every time the connection is made, then there can be something else going on that needs to be investigated. An inverter, appliance, or a few incandescent bulbs switched on would provide enough draw for a clamp on DC amp meter to read.
