Hi everyone! I’m a first time van owner with a 1991 B250 camper van and I noticed there was a phantom draw that was draining the battery when the vehicle was off. I was able to find out by pulling the relay for the ignition lamp time delay where the draw was coming from but now I have no idea how to fix the problem. I think I’ll need a wiring diagram to figure out what I’m even looking at down there. Is there a way to tell if it’s just the relay that needs replacing or if the problem is in the wiring? Overall, just not sure where to start. Thanks in advance for the help!
