Indeed a mulri-meter check will tell the story. Like thedudeabides took photos of, I did the same thing today. I get no measurable loss at the connector - none. There
has to be some improperly cleaned connections if a GGTS isn't hitting properly.
I realize that doesn't sound very technical but sometimes, simplicity is your friend.

If you are getting the same voltage at the atty connection out of the GGTS as you are from the battery when checked, how else could you have a problem in what is fed to the atty? I mean no disrespect to any of my GG friends but facts are facts.
Using the same
batteries and the same
equally cleaned connections, the distance the current has to travel is so small for the speed of the travel of the voltage, it simply isn't possible for a normal human to detect a difference. What is possible is for someone to be told over and over again that one thing is better than the other and the mind makes it so.
It's almost like the Noalox debate. Some swear there is a noticeable difference both with and without it but the science of factual measurements again don't mislead you. Sure, take an oxidized contact in the circuit and the measurements would be off on a scope. But everything being properly cleaned and maintained and it is the mind telling you more than the facts I think.
