Hello everyone! Looking for some guidance please. I recently purchased a old MR Darth Vader lightsaber from a estate sale For my son. Not sure what version of the ANH it is. It’s got a 6 AA battery pack and the power switch is up by the emitter instead of on the clamp. Not in terrible shape considering but the switch is glitchy despite no visible signs of a short and the swing sensor is super sensitive. It wouldn’t cut on when I got it because the battery pack wasn’t in the greatest shape. I scraped the original blade and added a red one and I’m wondering if I may have damaged the sensor? I have no idea if this was a existing problem or not or if it’s a common thing with this saber. Any help would be great thanks everyone
