Rewiring the a/c
This morning the battery on my truck was completely drained because I forgot to turn off the a/c last night. I think the genius who owned it before me wired it directly to the battery, so it stays on even if the engine isn't running. I while I was jumping it I noticed a red wire conected to the positive terminal, grounded to the frame and running into the area behind the dash. now here are my questions:
Is it safe to assume this is whats powering my a/c and draing the battery?
If it is where is that wire suposed to go and why would they jury rig it like this?
I did find the electrical diagram online but its a little confusing to read, and I dont know if this wire is the color it should be. I also tested the battery and it's still good. How long do I have to run the engine to recharge it?
