Hello everyone just wanted to know that is something wrong with my charging system or is it me. Its a 95 Fireblade. At idle it has about 15-15,1 without lights. With lights on it has about 14,9-15. When I rev the bike it drops to 14,5-14,6. To me its a to much and I dont want to fry battery. Rectifier (DUCATI ENERGIA) is new cos the previous died. The stator is checked and everything seems ok. What do You think?
That said, especially if it still has the original regulator without cooling fins, it won't hurt to fit a new one. Plenty of pattern or later honda regulator with cooling fins. You can fit a 12v 40mm cooling fan on those.
Checked with another multimeter and shown 14,8 with lights and 15 without. The rectifier must work cos when I rev the charging drops till 14,5 no less. Manual says it should be 13-15,5 so I think its only in my head
Reiterates it for you all... really? Nobody read it completely? Is the intensity and speed of the internet finally weighing on humanity?
(I've been away from a bunch of this stuff while working the past year or so in anticipation of my kid, and everyone seems so much more disconnected since I've been back... maybe it's just me having slowed down too?)
Being an aficionado of sorts with the 900, I can say for sure that it is when the system is hitting 16v+ is when the issues arise, 14-15.5 is totally normal and regulator is doing it's job. I ran 3 stock before I went to a finned Suzuki GS500 regulator that solved all issues and could handle the spikes that the 900RR seems to have for no good reason at all.
Sometime a failing cell in the battery makes the reg/rec output higher voltage. When I put my fh020 on my fighter with the old battery it read 17v (the battery was fubar), I replaced the battery and now charges at 14.4v
people are running into these issues in cb750/nighthawks when theta phrase stator/rec, and are combatig by installing something that limits the voltage output.
