My son bought a used 2002 CBR600 form a friend who had replaced the front turn signals with low profile, side-mounted LED signals, which blow the 10A turn sig/horn/stop light fuse after a few uses.

There look to be 9 or so LEDs in each turn signal.

Obviously, the power draw is more than 10A but I had always thought LEDs drew less current than the stock front signals would.

What do you think the problem might be?

1. Improper wiring? The signals work until the fuse blows?

2. LEDs draw too much current?

3. A wire is being shorted out?

4. Other???

So what are my options?

1. Replace the 10A fuse with a 15A fuse? Probably not the best idea, but what say you?

2. Remove the LEDs and start over? PITA due to having to remove the front fairing.

3. Is it possible to remove 1/2 of the LED lights? I assume they are sodlered to a little PFC board

4. Other ideas that might allow me to salvage everything that is on the bike?

Thanks,
Greg

 

Alright, I'm not going to pretend to be an expert here, but i'd be willing to bet the farm that it is NOT the LED's drawing too much current.

Based on the fact that a kid did it, i'm willing to bet the connections are either not sealed off properly and are touching off on something metal, or the wire job got botched and the connections are crossed somehow. It'll be worth taking off the panels and exploring the wiring. buy a box of fuzes and determine WHAT causes it to blow.

once you determine the cause, the correction won't be difficult.

 

I agree^^^^^


there is no way the led's are drawing more power than the stock units. Its gotta be wired wrong or shorting out somewhere.

I would start the bike, turn the left signal on for 1 minute, if it still works, then put on the right. If it still works, apply the rear brake with the handle bar, if it still works, try the foot brake. One of those has to be the culprit and should pop the fuse.

You might want to check out the brake light too. Its always possible the kid put the wrong bulb in and its blowing the fuse. But I would guess its just not wired correctly.

And like you said, putting in a larger fuse will not be good idea. what ever is blowing that fuse will surely just melt the wiring instead of the fuse blowing.

Another thing to consider. Is the 10 amp the correct size? make sure its not undersized.
