Slow Car Fast
December 26, 2010 - I decided it would be a quick and easy thing to check the fans out by just grounding one of the wires on the relay.
I tried it...and nothing. A bit of probing with the test light revealed there was no power at the relays - and a check at the fusebox showed two blown 20A fuses, one for each fan.
Looking at the fan ratings, they're supposed to pull around 13-13.5A. But that's continuous running. I don't have the specs for a startup draw on these particular fans, but one other Spal I've used in the past has a continuous draw of 12.5A and a startup draw of 18A. So it's quite possible that my fuses simply weren't up to the task. The wiring could certainly take it, so I'll just drop in a couple of 25 or 30A fuses and see what happens.
