help needed with new hayabusa loom
i have the sbd hayabusa loom and mbe 992 ecu on my caterham and am assuming i no longer need the standard busa reg/rec ? as there is no where to re
connect into new loom?
am i correct in thinking its job is to regulate voltage and send surplus voltage to keep battery charge topped up? cheers

Hi Daniel,
You definately do need the rectifier/regulator but it is possible that you don't see any connection in the new type harness.
Although I have not seen the new harness, I can imagine how to deal with this and it does not need to go into or out of the new loom.
On your engine you will see 3 wires coming out of the generator coloured yellow. They are quite a thick wire so should be identifiable. Your Rec/Reg
will have a 6 block connector with 5 wires in it. 3 black wires to connect to the 3 yellow wires from the generator. Usually this is done via the
wiring harness but in your case, can be connected straight to the generator. There are 2 other wires on your rec/ regulator, 1 black/white and 1 red.
These are 1 common earth wire (black/white) and 1 common live wire (red). Normally, the 1 red wire would be connected via your starter relay. This has
a large 30 amp fuse in it and will protect the car against a short in the rec/reg. If you still intend to use the original starter relay you can
connect the red wire to the fused side of the relay. The black/white wire needs to go to a very good earth. Depending on where you mount your rec/reg
will depend on how you connect it to earth. I strongly advise connection to the crankcase and then you can use the heavy earth cable to connect to
your negative terminal of your battery. The rec/reg needs cold air flow over it so mounting in the engine bay towards the front of the car is good.
they get very hot so it is a good idea to mount it using the original plate to allow air to circulate around it.
If this is clear as mud, you may wish to contact me via U2U.
If it can't be fixed with a hammer then its probably an electrical problem.
