Talking about fans...

Since ive had the SEAC it has blown two rad fan fuses.
The previous owner warned me of this (he fitted a seperate fuse holder and "heavier cable" cos it melted the original)
Also on ebay there are some 40Amp spade fuses on sale

stating its a common TVR problem.
Is this the case? or is it likely I have an iffy joint/connection?
I have "borrowed" a 40 amp circuit breaker from work and am tempted to fit it. Any thoughts?

Is the fan on its way out? I have fitted 2 fans and they come in well under the 30 fuse and relay fitted (on paper) Is the new fuse holder just doing the fan or has something else found its way on to that circuit. And can you get a suitable meter in just to check the draw?

Found a receipt for new fans fitted a couple of years back.
Will be taking a "tong tester" to it tonight to check the draw.
The Kenlowe kit I fitted on the 350i had to have a 25Amp fuse to each fan so maybe thats the problem ie. the standard wiring is for a single fan and TVR didn't think it neccessary to upgrade this for twin fans!!
Cheers Jeff.

The twin 16" kenlowes on the 350i are rated at 20Amp each.Not sure whats on the SEAC other than they are Kenlowe.

streaky said: Fans (on cars) generally don't draw a lot of current. I'd check what's going on before uprating the fuse ... took much risk of fire IMHO - Streaky I have seen 5A running and 24A stall (startup) currents before now. It's the stall current that tends to take out the fuse; what they really should fit is an £8 circuit breaker with the appropriate overload curve... oh, but that would put £1000 on the price of the vehicle wouldn't it. Sorry, I forgot. Ian

yep thats what I'm going to fit but can't find a 30Amp one. Do you think 40Amp would be a problem Ian?

Cheers Steve - I forgot to bring the tong tester home to check the startup ampage but its definately surging at over 25 Amp. Like Wedg1e says it would be on startup only and would then tail off. Ive got a 40 Amp breaker, sounds high but I did a calibration on it and it trips at 32 Amp so am confident that its "safe" to use and its much easier to reset than fitting new fuses (especially when in traffic)
Hope you enjoyed Salcombe, I know it very well and the drive around Batson Creek at sunrise in a Wedge is awesome. I'm looking at 2 pictures of Salcombe above me fireplace as we speak.
