If I unplug the blue wire at the fridge relay under the seat, the LED goes
out. I rarely use 12V on the fridge, so is it safe to leave this off?

Bentley also suggested measuring between 9 & 13 at the intrustment panel
connector - should be 140-160 ohms. I get 500 ohms which climbs to 800, so I
assume there's a cap in there that may be failed? This seems less definitive
than the blue wire at the relay however. The panel connector is very touchy
so I need to try to bend the terminal pins to squeeze the foil contacts
better.

Then I'll try running it with the relay wire off an see if I get any
charging.

Thanks
