I have a 2003 Suzuki Volusia that blows the 15 amp ignition fuse randomly.Can go weeks without a problem then it will blow. I replace it and it is fine or other times it blows repeatedly.

hi there.
see if this link helps you out.
2001 suzuki lt300 20 amp fuse blows Google Search

you have a short.
check wiring near head stem and handle bar switch blocks

Try 20amp fuse ?

something connected too ignition sdwitch has short to ground. remove all fuses except 20amp that blows turn on ignition see if blows. if not replace one by one till it does to isolate circuit. which fuse is blowing and where is it located.

FAULT IN PCM OR FUEL PUMP WILL CAUSE FUSE BLOWING.

Did you also check the system fuses? The fuse box is located behind the left side crankcase cover above the coolant reservior.

The 15 amp Signal fuse protects the coolant temperature light, the turn signal indicator light, the neutral indicator light, the oil pressure light, horn, brake/taillight, postition light and turn signal light. Basically, if this fuse is blown, your cluster will be inop.

Please let me know if this is helpful.

Check the oil level. If you are lucky there was too much oil and this may have been some blow by. More likely though, you may have blown a piston ring. If this is the case, you will have to overhaul the engine or drop in a new one. By the way, was the bike laying on the right side for any length of time?

Theres definately something wrong in the circuit of tht orange wire ...try to follow it up as to where tht wire goes and you will probabely find the short.
Hope this helps.

for a short fix it will work, but more than likely will blow that too eventually, it is that amp for a reason and anytime you are putting a bigger amp fuse in you are putting less protection into that part of the system which could result in the parts on that loop to be damaged.

Usually if the fuses blow constantly there is a short that is doing this, my advice is work out what that fuse is for and investigate that problem than trying to bypass it with heavier fuses.
