I liked the idea of changing the indicator LED on my Westy from the anemic
green to a bright blue as one of the other folks had done (I bookmarked that
page for later reference). Did it this last weekend. It was much easier a
task than I expected (I should have believed the 30 minute estimate noted on
the web page.)

So I was excited to see it in action and wouldn't you know, couldn't get the
fridge lit (I'll have to follow up on that, as it was working last month.)
Not   a big deal as I was going to pull the fridge anyway to do the change
over on the coil fan.

Anyway, I was experimenting with a few things and threw the fridge over to
battery mode (engine running)...and the indicator light turned on. Couldn't
miss it. However, I didn't expect it to be on when in battery mode (and the
circuit diagram doesn't indicate that it should be on either.) Interesting.
Have to investigate this more fully.

Curious thing is, the Bentley manual mentions specific colors for the water
level and battery LEDs, but on the propane indicator the text does not talk
about its color. The diagram refers to it as a "red" indicator (and all the
manuals refer to it as "green".) Blue does seem a much better mnemonic though
(however, it should be noted that blue LEDs did not exist up until a few
years ago, so it wasn't even an option when our Westy's were made. )

The hardest thing about switching to the blue LED was finding the stupid LED.
I went to 10 different Radio Shacks before one had them in stock (how all the
Radio Shacks ran out of stock at the same time is beyond me.)
