3000M Twin Fans / Otter Switch
Discussion
Hi
Need some help!!
1975 3000M with a SPAL twin fan set up installed around 15 years ago by previous owner. No apparent electrical override switch currently wired up.
I need to establish whether both or either fan is working.
Am I right in assumming the fans are controllled by the otter switch and this simply opens / closes when hot thus making the electrical circuit by connecting to earth? If I'm right then if I disconnect the incoming cable to the otter switch and earth it directly then the fans should come on or is it more complex than that?
All help and advice appreciated
