Battery charge relay.

[westy64]

Prunette still has the battery charge relay, but I do not understand how it is wired.

Relay is a SIPEA 0444 which I think is a "Normally closed" unit, but it is wired according to the following.

87 and 86 bridged and wired to ground
30 is linked to fuse L passing through the battery charge indicator
nothing goes to 85.
nothing on 87b
I thought it should have received a power on 87b to open the switch, and shut the light off.
Am I wrong ?

Thanks
