Needing help with my 03 GSXR 750 when I start the bike it stays running for a couple minutes and then shuts off I checked the wires checked everything and then I seen that my fuse was blown on the battery so I changed it tried it again did the same thing I've blown eight fuses and had the bike running for a total of 6 minutes probably does anyone know what the deal is.

The main 30A fuse?

Yeah, it's a blown fuse.

Ta dum, cheesh! I'll be here all week, thank you!

Seriously, a little more info. How long you've had it? When did it run good last? What have you done/changed? Etc.

Try unplugging the reg/rec. Replace the fuse and start engine again. If it stays running, you've a faulty charging system.

= short circuit.

Use a multi-meter. Find the short circuit.

+1 to last. Faulty generator or regulator most likely. Check starter solenoid circuit too.

(No multi-meter? Take it to someone who understands that to find an electrical fault one needs electrical tools.)

 

[RacerX518]

The stator & R/R have zero/0 to do with ignition. It'll run on a fully charged batt till it dies. Ignition is the keyswitch, killswitch, start button, safety switches, etc. Without being there, the main fuse blowing over and over sounds like a short/hot wire exposed and touching somewhere in the harness.

 

[MadisonMotorsportUK]

Over voltage can cause ignition failure. I agree it may not be the issue directly but it's worth ruling out.

 

[QRO]

I think we need to avoid encouraging people to come here with electrical faults by giving them any impression it's possible to diagnose such faults with a screwdriver and a hammer and some wishful thinking.

Electrical faults require electrical tools to tell you what is happening.

• Battery voltage?
• Ground resistances?
• shorts?

 

[MadisonMotorsportUK]

+1 but also an understanding of how to use said electrical tools and how to interpret the results.

Try a new”ecu” ✔

Yeah, because throwing parts at a problem is the way to fix it.

🤣🤣🤣🤣

Any update on this?

I've tested the stator and the regulator they were both good I tested them not plugged into each other and while they were plugged into each other and that was good battery holds a charge and it the bike will start and stay on if I have a jump box clipped directly to the bike itself with and without the battery connected to it but as soon as I take the jump box off all power dies I've went through all the wires to see if there was a short circuit somewhere I didn't see any only thing I have not done was test the solenoid. But still I'm not understanding why it will run with the jump box but not without the jump box and the battery hooked up to it?

 

[rv6john]

How, exactly, are you hooking up the jump box? A picture would help.

 

[Yellow Submarine]

If I understand correctly, the ground from the jump box is on the frame or other point rather than the battery?

If that’s the case your battery has a faulty ground.

Well….wishful thinking and lots o’parts. Hammer & screwdriver optional. 😁

😂😂😂😂

So just to the same battery terminals. Are you sure the battery is good? Like you put a voltmeter on it while you were cranking?

 

[chrisclark66613]

Just now did that and it read 12.4 before I turned on the bike the it dropped to 9.2 while cranking.

Yeah, that’s not a good battery. Charge it overnight on a 2 amp trickle charge and try the same thing again. Note how much voltage drops off. If it’s the same, the battery is junk.
