Chris A Posted July 9, 2018 Report Share Posted July 9, 2018 Hi everyone I've looked in the manuals I've got but can't find any information about the power consumption of a Smith's heater fan Do any of you know its consumption and what fuse would be correct for it. Second incidental question, why does it take its positive feed via the stabilizer and not from "raw" battery power? Thanks Link to comment Share on other sites More sharing options...
Paul H Posted July 9, 2018 Report Share Posted July 9, 2018 Hi , my best guess is that you would be covered by a 10amp fuse - I upgraded mine to a Nissan blower and that needed a 15 amp fuse which i connected to direct feed together with a relay Hope this helps Paul Link to comment Share on other sites More sharing options...
Dave1360 Posted July 9, 2018 Report Share Posted July 9, 2018 I seem to remember mine taking about 5A, so I'd go along with Paul's 10A fuse suggestion. It's probably taking its positive feed from the input to the stabiliser rather than the output, so it is "raw" battery power. Dave Link to comment Share on other sites More sharing options...
Chris A Posted July 9, 2018 Author Report Share Posted July 9, 2018 Paul & Dave 13/60 : Thanks for the replies. I looked at the wiring diagram again - this time with my glasses on - You are right the power is from the input side hence "raw" battery power, which is what I would have expected.

daverclasper Posted July 9, 2018 Report Share Posted July 9, 2018 Just switched it on and showing 5A on my dash amp meter. Dave Link to comment Share on other sites More sharing options...

Anglefire Posted July 9, 2018 Report Share Posted July 9, 2018 Fuse for the wiring if you have nothing else to go on as that is all the fuse is protecting at the end of the day. Might be lucky if the motor starts to fail - but even then it’s knackered 9 times out of 10. Link to comment Share on other sites More sharing options...
