Learning curve

Hopefully I've seen a back of unproductive weekend work on the E30 for a while.
Last weekend was this:


Which doesn't look too bad, well, it does. It looks like the finest 70's Italian designed electrics. Sadly it was about as functional as that too.

But I've learned about relays, feedback loops and poor earth connections. And as a result of this I now have a three way switch instead of the BMW standard window circuit breaker.
What did that do (the breaker?) well, it allowed you to override the entire circuit for the power windows. Which seems like a good idea. Except, on my car it meant illuminated switches the entire time, or windows off. And with no air-con/heater (more on that later) they're going to be turned on a fair bit. And that means a flat battery more often than not.

So, now I have a three way switch - Off / On / Ignition - which literally means I can forget about the switch now. Handy, as I want to.

The heater? Yes, the heater. It's disconnected on my car. So I reconnected it. And then I flooded my garage. And then I disconnected it again.

No heater for me, or rather, quote from a mobile mechanic time: "Please remove from car B and place in car A" - I'm not doing it, it's one of the all time worst jobs out there. Anyone fancy earning a couple of hundred give me a shout.

Finally, this weekend is get car running weekend, finally.

Wish us luck!
