Reg/Rec

Been reading up on the woes of this particular part and guess what mine has died
Been i to a shop local to me and he will supply a new one for £60 which seeing second hand ones on ebay for 45-50 seems reasonable.
Ok I read an article from someone in the USA who saw sufferers of this part quite regular and his mate an electronics boffin said it was the heat that killed them and went to some depth explaining what happens, (course cannot find the flamin' link) Anyway the position of the reg/rec on the SV is hardly good for cooling and due to heat transfer to the frame and engine position (not to add re-wireing) makes moving it forwards a bit of a 'mare, Solution? fit a cooling fan of a PC CPU, draws little current and passes a decent airflow over "the grill".
It does seem to work according to them so the new one will have a fan addition once done and tested I'll post an update.

interesting idea.

This has come up before, however the problem is sample size.

Some SV's never ever blow a reg/rec. Other reg/recs fail relatively early on. Suzuki have mounted reg/recs to the engine in the past where you'd assume heat would be more oppressive and they've been no less reliable.

So when someone says: "I've fitted a cooling fan, and 6 months later my reg/rec is fine" it doesn't actually help, that reg rec may have been good for 10 years of hard service without a fan.

However, I can't think of a reason not to do this, provided you're sensible about how you wire in the fan, so that it won't run with the ignition off, but so that if it shorts it should not short out the main live ignition, Anciliaries like the main live for indicators etc are common ones.

I wouldn't imagine PC fans would be too resilient when treated with the finest of british weather TBH.

Easier to fit a more robust unit.

I thought that about the wireing thanks, the things do get hot, really hot! just idleing for about a min and it was getting quite warm, when under load I reckon the egg butties will be a sure fire hit

Not the wiring, the fan units themselves. Are they brushed motors? Are they sealed at all? Or is the com just going to get covered in salt and frazzle?

actually tho' they don't look it they are! Your bike don't run everyday 24/7 365 days a year, the pc's at work do and they survive that. Anyway tucked under the plastic I don't think weather will be a problem, just had a thought tho' how long before someone tops this idea with a water cooling system fitted on high end gaming pc's

My bike runs nearly 365 days a year and the h*nda reg-rec on it isn't on fire yet!

But you get loads of salt spray, even under the tail pod! A PC fan is running in a dry environment, with only a little dust to contend with. A sight different to an environment which is hot and exposed to salty water. You can't honestly believe that something running under steady state condition in near perfect environment is a thorough indicator of somethings robustness?

A simple example, a drive chain running in an oil bath will last for ages(some MZs use this) . You couldn't expect the same life out of one on an SV out in the weather.

By all means give it a go, but it seems like a long way around it when a much higher rated reg rec is so cheap and wires up no problem. One from a CBRRR is £40 or so and they're a tough unit.

you ever opened a pc!! Take your point but its got to worth a go,I have read the CBR600 regs are not to highly rated on the Honda but seem to love Suzuki's and astonishingly vice versa.

Ps forgot to add I have a "spare" fan knocking around

Ah yeah I remember it form a little while ago as well.

Here's a prime example of reg/recs differences... the current SV (2001 SY) has it's original reg/rec fitted still and has covered nearly 35k and is still going strong. my first SV (2000 SX) needed a new one at 17k which was fitted by the dealer just before I bouhgt it
