I just went through this whole thread. 1) This is an awesome project, 2)you've had some strange luck.

Let me ask you some questions about the solar side-project:

I have a 30w monocrystalline panel, a battery isolator and a charge controller. Can you maglock the panel to the charge controller and hardwire the charge controller to the BMW, or should you put the maglock at the end of the entire charge circuit after the controller (will that even work)? It looks like to ran the receiving end of the maglock to the battery positive and the negative stud in the engine bay, but could you not run it to ground and straight to the battery in the rear?

I'd like to run TWO batteries, and be able to draw current off the non-starting battery, but remove the panel when not needed (as you probably move it around from car to car).

BCReds battery disconnect idea is great, but where he put it is not for me. Totally agree on the main-line battery disconnectors that live ON the battery being a super pain in the butt, but they are more direct and make you feel really sure about their operation.


Final question back on topic, how much did that whole thing run you, in the end?
