Well not much to offer here,but thought I'd better contribute something to justify my world...and also so as hoser don't sack me!
I've been having real bad reliability probs with these Tridon thermo fan switches,so I'll be replacing with the much better quality/perform Teddington UK adjustable switch like I bought for the Drakart.
They only seem to last about 1-2 years,then crapola.
The UK Teddington brand is not only top quality,but very reliable so far,no probs with it being 8 years old in race conditions.
There are diff temp range models,and why I'm using these because you can go down to any temps.My goal being around 65c-150F start fan.
Why those temps you say? Because it's what I've learned from people in the know eg Ian Williamson racing,Rotax and Arctic Cat data/info.
They all recomend around 65C-150F for bestoptimal sled motorHPpowerresults.
The Tridon unit in pics was good at 55C start,the closest I could get locally,but keeps crapping out and not reliable.
Last event at Hedley Park,the FL800 was running hot at the day's end,traced it down to ANOTHER dodgy Tridon switch.
So I fitted it on the FL800,and AC550 next when bought.
Also fitted some HID lights on the AC550Pilot as looks like our ol venue at Northam Speedway looks to be coming back regular,nightime events?
Here's the Tridon unit:
Here's the Teddington unit put onto the FL800:
Hard to see here,but at 9 o'clock there's a small/tinyTim adjustable screw for kickin temps.
It also has a rubber gaitor cover:
Here's my new HID's,awesome light.
