Fireblade 900 Charging Issues
Hi all, new to the forum, and after some help with a charging issue with my bike. (I've already searched and searched but can't find any definitive answers)
I recently bought the bike and on the first ride it fried the reg/rec. With it having an RSV1000 seat unit and sub frame on it I noticed that the reg/rec was only mounted on a small thin bit of plate that was bolted to the plastic undertray. Thought I'd solved the problem by re-mounting the new reg/rec on the sub frame so it had a proper heat sink (with proper heat sink paste). Checked that the battery voltage was OK (14.5v) then set off on a ride. Again it fried the second reg/rec!
So far I've checked...
Generator resistance (ok)
Bought a new battery
Made a new wiring loom as the connectors were burnt
Mounted reg/rec to the sub frame
What I have noticed is that the reg/rec was getting hot quick. The 3 phase wires from the generator were getting warm! I tested the voltage across the phases from the generator, but with no definite answers i'm not sure what readings I should get at what rpm!?? I also did a load test on the each of the phases and got 20A at idle running speed! No wonder its getting hot! The load test on the red/white wire from the reg/rec was 7A at idle with all lights on.
The only reason I can see the generator phases pulling that much load is because the reg/rec replacements I'm getting are bad. And as you've probably already guessed it, my second (the bikes third) reg/rec has fried!
I'm at a loss as to what to do next! Someone point me in the right direction!
