I would guess coincidence.

Yeah that's what I'm thinking. Any ideas why disconnecting the switch block stopped the short?


I'd have to check the wiring diagram, but knowing Ducati they probably have the feed running through the switch an then back to the sender.

Ok so the fuel sender does go through the switch block, but I unplugged the sender and it was fine, then I rode it for a bit and it blew. It seems when I'm testing it on the stand it will blow when it's on the stand but not when it's upright, and it'll only do so for a few minutes, at which point it will be fine and only blow when I ride it (usually).

I'm baffled....

Do you have a wiring diagram?
If not would one for a 96 help you?

I have the haynes wiring diagram.

It's annoying because it'll blow consistently for a few minutes then stop. Like I can wiggle every wire in the harness and it won't blow. When it's at that stage I can't try unplugging things because it's never blowing anyway.

I reckon! I'm going to scan my wiring diagram and edit out all the bits that are not on the circuit, so I can see what to try.

Damn Italian electrons more like it.

Sorry for jumping in, just ignore me if I'm in the way.

- Took bike off pit stand and put it on sidestand. Blown Fuse as soon as weight went onto the side stand.
- Back on sidestand, blown fuse.

Have you wiggled around the switch housing on the left handlebar with a good fuse installed?  Were you actually holding the left grip when these blew? Maybe something is shorting inside (I know you replaced it 2 years ago, but something may be moving in there)

OK Weird Fact.

I get continuity across the terminals for the fuse in question with the fuse out, but only when there is no power through the circuit. This is not normal, no other fuse terminals do it. Any ideas what this means?

I'm also getting continuity between both of the terminals and earth, when the bike is on or off.

This doesn't seem right but I have no ideas what it might be indicating.

Any fuse that is not switched will be hot with the key off.  Off hand, I think this will only apply to the main relay fuse.  Hot on the other side would have to be a backfeed from something else, I can't imagine what since nothing else is hot with the key off, oh, maybe the ignition switch itself.  Pull the main relay and see if terminal 87 is hot.  The problem, though, is this does not explain your original foose blowing description [bang]  You have a winner here. 

Oh, use a circuit breaker of the same rating as the fuse instead of fuses.  This will save you time, money, and frustration.  An inductive ammeter can also help in locating a short.  Run it along the suspected wire.  The meter will pulse as the breaker cycles until you get past the short.

Thanks Howie, I'll try it out.
