In preparation for the warmer weather, I decided it would be a good idea to have a radiator fan indicator light to see when the fan kicks in. With the large and full grill block this will let me know if I need to open it up or not.
The implementation was pretty easy. I pulled the radiator relay out and shoved the small wire into the blade connector end of the closed side of the relay. Then, I just grounded the other wire on the negative battery terminal. The light is an LED with a restistor. When the fan kicks in, the light gets power and lights up. Pretty simple, and pretty ugly, but it works.
I also removed the other two batteries from the car. After a week of sitting, the batteries had discharged themselves down to 12.2V due to being unbalanced. I imagine it wouldn't be as bad if I drove the car daily, but that is not the case. Plus, the added capacity really isn't needed.
