Hey y'all. I'm honestly lost and feel super down.

  • Facts: CBF1000 sc58
  • Last thing I did was get my alternator and regulator repaired/changed. My alternator was burnt out. The mechanic said that it's am usual problem with this model and the regulator is the problem.
  • I had to learn to take it out and rebuild it myself. About a month ago, I finally put the alternator back in and my bike actually started! I was overjoyed.
  • Since a week now I'm trying to actually ride it again and it won't start. I recharged the battery (Li-ion). When I tried starting it, the battery kinda drained immediately. It just didn't start. Luckily, I have a second (gel) battery that was full. I put that in and my bike didn't even light up. The fuses all look fine to me. The cables should be correct (there aren't that many options).

I just don't even know where to start. Thanks for reading

Thank you so much. I can try that tomorrow. But I didn't change anything about the cables since it started last time. I have a multimeter, so I guess I measure stuff.

The contacts will oxidize over time, especially with high humidity or exposure to salt air.

Often just loosening/tightening connections is enough to get it working. Better still is loosening, then contact cleaner, then dielectric grease, then tighten.

You have already done the battery connections, so check the frame ground, the starter relay (that's hot only), the start switch (again, hot only) and on from there.

You'll get it. Motorcycle electrics generally suck shit and are subject to harsher conditions than a car, at least it isn't a 1960's Triumph.

But that's happening in one month? It started like 4 weeks ago... I wouldn't even know what connections to loosen. I'll have to read a electric dictionary to understand your message, but thanks so much for your help and suggestions 😁

It probably wouldn't have happened in one month, it just got worse until it stopped working.

Battery negative — will connect to the engine. The black cable coming from the battery. Loosen that, give it a wiggle, tighten again.

Battery positive + will have a large red cable, and some smaller ones too. The large red will go to the starter solenoid, loosen that, give it a wiggle, tighten again.

That's a start.
