It's time for some serious troubleshooting. WHY do you think the signals are draining the battery? Are they on all the time the battery is connected? If so you need to track down their source of power. Turning the ignition key off normally kills power to everything on my tractor. If that is true of your tractor as well you have a phantom power path somewhere. It could be a challenge to track down. You could start by pulling fuses to isolate which circuit is doing it. If that doesn't do it the problem is somewhere in your wiring, perhaps insulation worn through at some point or chewed by rodents.
