Hi - the photo is from an Italian gelato cooler: ISA Samoa.

The cooler is 30 miles away. I'll be travelling over there next week to have a closer look.

I can't say whether the wire is coming from the compressor, or just passing under it.

Anyone have any thoughts to share about that grn/yel wire?

My guess: the compressor is on rubber feet, so the wire grounds it to chassis?

Thoughts?

Thanks!
