The R1/R6 unit I fitted had a slight recess on the back which limited the surface area against the frame. I guess the unit is big & finny enough but I stuck a bit of copper plate in the recess which filled out the (I dunno, less than a mil?) gap, using thermal conduction paste. Probably a bit OCD but I figured it maximizes the subframe's heatsink properties.

Would this modification be ok on the 2004 model. There is no separate earth wire, it's all in the block connector. I've just got home from a four day trip and think mine is fried. Wires burnt and battery goosed.

Bob,
also make sure you replace all the suspect wiring and connectors, they will be high resistance and continue to cause problems even with a new R/R

Cheers for that fellas. I've already cut the old connector of and stripped the wires back to good stuff. Also soldered the ends in prep for joining. Hopefully the modification works. Fingers crossed. Cheers again. :D

Hi guys,

Just thought I'd run this by you all. I've purchased this:

http://www.ebay.co.uk/itm/390608655150? ... EBIDX%3AIT

Do you think it'll be easy enough to slide the old spade connections out of the old connector block and into this without having to cut and solder wires? Guessing I'll be able to slide a small screwdriver in to release them one by one.

Yes you can get them out with a small screwdriver...IIRC there is a small tang locking them in on the top of the connector...Bear in mind what has already been said about checking the wires & cutting it back to good first...

Yes, of course. I haven't had any problems yet but haven't taken a look at the connector... Could be melted!

Found this one at £19.69
plug and play I think

Interesting that the seller lists one for the Storm @ £22.50 but is the same part.


tch!

I know its only £2.81 difference but that's a pint of beer in these parts (and some change back)

Be warned that these can still fail. Yes they are a better bet than the std block type one fitted by Honda but it's still a shunt type so is still fallible.

Save some pennies & look out for a Mosfet type one...

I know the add says it's gaurenteed for a year just hope it doesent melt in 366 days time... :lol: :lol:

Nor are mine. Which is why on one I re-crimped with the correct kit (square type crimping tool for the correct crimps as per the origionals...Cheers Wicky for the loan of your tool.) Having bought the fitting kit...http://www.ebay.co.uk/itm/FURUKAWA-CONN ... 58a3ed5c40

On me F2 there were clearence issues as the ECU lives on the side of the subframe not under the seat. So I just unpicked the block connector & used the origional connectors straight onto the terminals.

The possible problem with the plug & play method is that the origonal wires may be damaged & burnt which would require cutting back.

Thanks for taking the time to respond so fully and the pics will help when fitting

So this one should do the job?

I'd be wary, even though it appears marked as an FH R/R, at that cheapy price and origin it could still be an SH type R/R.
