Fuse question regarding increase in amps 11 Months, 3 Weeks ago  
Are there any negative effects from increasing fuse amps?

e.g.: 5 amp to 10 amp, 10 amp to 15 amp, etc.

I ask because I read on another forum that a guy "corrected" his odometer problems by increasing the 10 amp fuse dealing with it to a 15 amp fuse. Also curious to know if this is a possibility -- or maybe just something that occurred by chance during his switching of the fuses.

I dont know how thats possible. bigger fuses makes smaller wires hotter.

does it really make them hoter or just allow them to get hotter and melt before the fuse pops like i always figured

Depends on how big of a fuse you put in. But if you get them hot enough to start melting the insulation then the wires are ruined anyway. So you end up having to change out the wires as well. Don't ask how I found that one out

There may have been corrosion on the fuse legs causing intermittent contact.

Bigger fuses let more current flow before they blow. A bigger fuse in,and of itself is not a problem. They are there to protect the circuit from melting down in the event of a malfunction. If there is no malfunction, a bigger fuse is not an issue. If there is a malfunction, you risk the circuit an everything in it.

Since your lights and clock/odometer is working, that tells me that power is getting into the meter. Those are typically good signs. As I peruse my manual, I see that the meter lamps are listed as 14volt, 1.7watt X 3 bulbs. That is a bit odd, since the rest of thebike is (understandably) 12 volt, but may have been done deliberately, as protection for the tiny filaments from surge, but if the bulbs are capable of pulling 1.7 watts at 14 volts, will they not consume more watts at 12 volts? I'm not an ohm's law/watt's law guy, but I know several here are. I'm just wondering if those bulbs can cause an issue with the power supply to the meters. All of this would be internal to the meter assembly. It would not suprise me if the odo/trip meter was on a step-down transformer, and operating at 3 or 5 volts, as that's more standard for that type of equipment, but a step-down tansformer would not be affected much by a higher draw from the lamps, as it would be making a bunch of heat anyway, and conusumes only milliamps.

Just thinking out loud. I know we have computer software types here. Any hardware guys?

a fuse protects the circuit. if you go over the recommended one it can cause that part to fail permanently. Lets say the ignition module, lets say it's on a 5 amp fuse (as an example) and at 5.1amps the fuse blows, it protected the module. lets say you put a 10amp in instead, it might take only 8amps to fry the module, fuse is still good, but you fried the module, the proper 5amp would have prevented that.

As far as using the 12v lamps, been using them for yrs.

There are more speed sensor failures than there are speedometer failures.
