BEC Megablade - Solved rectifier issue - CBR1000 04 rectifier

[madmarkymark]

My original fireblade rectifier burnt out.  The replacement one still wasn't working.  So I searched for an uprated one and went for a CBR1100 2001 rectifier (seriously uprated) - however the output is 19.5 volts not 14.5.  I am told that the fuel pump is directly powered from this output and that brings it down to the 14.5 required. 

Therefore it is back to the drawing board.     Does anyone know a good rectifier to use with a 14.5 v output?  Space is not an issue, but it needs to be robust and not fry every time you use it !!! 

Any advice is greatly appreciated.  Thanks

I would suggest from what you are saying that you have a fault that is causing the rectifier to burn out. It's odd that one has burnt out and the replacement does not work either.

Thanks for the advice.

There was a short circuit deep inside the loom that was probably caused when the first one went.  I have now sorted that - but think that that caused the second one to go.  I have now run a separate wire, via the fuse box, to the battery.  When I fitted the CBR1100 01 rectifier it was all working fine - but the output was just too high.

try fitting a fan directly on to the heatsink wired direct to the ignition

this will help to keep it a bit cooler

done it on my busa last year - just in case 

hope you sort it

Fitted a new rectifier last night from a CBR 1000 2004.  It is seriouosly uprated vs the original fireblade one.  Only got warm (not glowing hot) and had a steady output of 13.9V.

Now I just need to sort the dodgy digital odometer and a host of other 'little' jobs and the Westy will be ready for 2012!!!

Well done, sorted
