charge trek VII - 'the unloader'

[tim eh?]

... from episode IV ....

-what does the 'unloader' relay do? I keep seeing it in wiring diagrams.

well... this is the unloader relay.



i still don't know what it does, but i'm pretty sure i need a new one.

there is no continuity between any of the terminals.

here it is in a wiring diagram... i was going to pull out the cluster but i think i'll deal with the easy stuff first.



tiger put me on the right track...

it's also hooked up to the dinky euro horns the PO installed.



have ordered one from the dealer that he thinks is a match - the numbers don't match anything he has but he thinks he has the right one.
shogun, may need you here...

here is the topside, sorry for the photo.

that is ...

602.039

61.36
1388745

pretty sure it is #3 here - could be #2 but the colour of #3 matches the one i have.



i'll dig around for that 'uncoupling diode' but otherwise i'll cross my fingers and hope it's the problem, not a symptom. i like the smell of this tho.

what does it do anyway? i noticed in later models (bentley 610-1) it is the terminal 'r' where i believe voltage is measured for the obc.

TBC...
