  1. suggestions on how to provide additional cooling then for the reg/rec?

    You know my answer. :)
    Its probably why Triumph moved the RR from where it was, near the exhaust, to inside the front fairing.
    To be honest, I'd look at getting the replacement RR which I think came out last year. That's a MOSFET device I believe rather than an SCR device and can cope with the heat much better.
    Alternatively, if there's space, you could look at fitting a small temperature-controlled cooling fan on the heatsink.

    What I want to know is, once the unit is replaced....which is essentially where mine is now. Is the replacement fitted by my dealer just as likely to go again in the future?

    If it'sreplaced with the latest unit, then it should be a lot more resilient so shouldn't be anywhere near as likely to go again.

    Well it IS Manchester. :)
    Make sure they're putting the new one on and not just getting a replacement old one.

    Will do the mechanic seemed to understand the problem he even said he would be putting the new one on as a few people in the past had further failures after replacements,just feel let down after the service I have had from Honda and yamaha dealers none of this nonsense 800 pounds deposit what! They have just 4 weeks ago taken 4700 of me the bike is in there garage but because I have no garage only a shed no courtesy bike yet hunts the Honda dealer no deposit and. Courtesy bike every time.

    The Honda etc dealers may change their policy soon - it's all down to the insurance and more insurance companies are requiring loan bikes to be garaged overnight and have a large excess.
     
  9. When the reg/rect overheated on my '09 SE, the mechanic at Brabant Motors (Grave, Netherlands) found a hair-line crack on one of the cross-link pipes of the downpipes while replacing the reg/rect. So being caught in heavy, slow moving traffic through Antwerp with the cracked downpipes exacerbated the over-heating problem. The mechanic said that he had seen a few Daytonas with this problem, since they buy second-hand low mileage Triumphs from the UK occasionally. So while you're in that general area on the newer models, have a look at the welds around the downpipes!

    On returning to England, Total Triumph took a photo of the offending ever-widening crack 600 miles later,and Triumph replaced the downpipes for free outside of warranty (by one month).

    I can only really add to this that if anyone fancies a DIY R/R change the 07/08 ZX-6R uses a mosfet, I picked one up for my 650 for £45 from that well known auction site and will be fitting it soon (got a week off coming and fancy tweaking the electrical system, bit of preventative maintenance)
     

  11. probably.....mine went last week, only 5 months after it was replaced. Especially if its the older 675 like mine is, i'm going to move my reg/rec from the stock position when i attempt to fix it this weekend.

    :?: Are you going to fit the new MOSFET type mate, or the standard (flawed.?) version.?
     
  13. Mosfet! I've picked up a couple off ebay now, so i've got a spare if it goes again.
     
  14. Just want to add my 2 pence....!

    I live in Dubai and ride in temperatures of up and some times over 45c, if its a heat issue why is mine ok? (God I wish I hadn't tempted fate by typing that!) I have a 07 with the rear mounted reg-rec.
    I did have my reg-rec connector smoldering a few months back which was caused by corroded dirty contacts on the loom/reg-rec 3 phase connector - cleaned them up and been fine since. Besides if it were a overheating issue you'd think that moving it up to the stale air behind the headlight faring would be worse than dangling above the swing arm?

    On a side note - I run a race series of British built formula cars (www.FG1000.net) that use GSXR 1000 motors. The manufacturer located the reg-rec in a somewhat sealed area via an extension lead. We had every one of them melt the cables on the reg-rec and extension loom mainly due to resistance caused by inadequate grade wiring on the extension leads and twice the number of terminals for resistance. We relocated them to an area with more air where we could do away with the extension, we cleaned up the contacts on the terminals and we haven't has a problem since.

    My advice is to regularly keep the connections clean, tight and greased with coppaslip or vaseline (especially in the UK where is pisses with rain every 40 min!) It helps prevent corrosion - should do the same with your batt terminals too.

    45C isn't a problem for a RR unit, and although it means there is less cooling available from the air it doesn't mean it's going to run hotter. Above the swing arm you get the additional heat from the exhaust when stationary which can be considerable, at least behind the fairing it's cooler, but you will get heat from the radiator when stationary so it's also not an ideal spot.
    Dodgy connections means there will be more current drawn and so more chance of the unit failing - so yes - do make sure all your connections are good (the surfaces which touch should be corrosion free but the bits that don't touch don't matter) and waterproof them if possible.
