RC Tank Warfare community hobby forum

Ok, so I am new to the RC world. About two months ago, I stumbled upon a random mix of 5 Rc tanks (1/24 and 1/16), mostly vs tank. However, with no controllers, I never got around to finding vs tank controllers or replacing receivers. I finally got a controller for the Tiger 1 vs tank. However, I feel like the AA batteries aren’t making a connection somehow. I want to simply find the power wires and bypass with a nicad battery—but I have NO idea which are the two battery wires. Please, any suggestions would be awesome!!!!

OK.
I have added some images of a lower hull from a VS Tiger I. Your routing may be different...
The VS uses two sets of AA batteries that are mounted perpendicular to each other. That means there is a connection between the upper and lower battery "trays".
Looks like the blue wire (-ve) to the switch and the red wire (+ve) to the 6 pin JST connector.

Maybe this will help you?

Good evening,
Personally, I don't think changing the type of battery? Nicd or Lipo (which I would not recommend?) Solves the problem. It is necessary to look if the various contact blades, are not oxidized or relaxed? then I would advise to use a multimeter, which will allow you with certainty, to locate the plus and the minus, and also to check if the batteries are okay.

AS Jofaur indicated, the easiest way to determine polarities, or where the power is coming from and going to, is to use a multimeter or a continuity tester.
VS tanks are a rarity here on RCTW, by the way, and the video linked to by Jarlath is actually very interesting.
