That happened to my Vulcan too. The plastic corroded the battery tray, so, even after cleaning and swapping for new batteries, the blaster didn't work. I solved the problem by wiring a 9V power supply directly to the blaster and modifying the battery tray to keep the stock appearance. The deal is: I used it as a stationary turret until the motors stopped. (Due to wear or something like that. I don't know. I'm Pedro the Mechanic, not Elliott the Engineer. Anyway.)

If you want to use the shell, go ahead, because that electronic plunger system is very annoying to mess with. I would remove it and put some flywheels to good use inside that blaster.
