Hi IllinoisREI,
If your current leak goes away when you remove the 10 amp "Fuel" fuse, then you are getting close to solving your problem.
I have the wiring diagram here for the SV650K7 which shows
Battery12V => 30 amp main fuse => B/R wire => 10 amp "Fuel" fuse => R/W wire
The R/W wire then directly supplys 12V to the following four components only:
1. Fuel pump relay,
2. ECM, (Engine Control Module),
3. ISC, (Idle Speed Controller),
4. Speedometer,
Unplug each of these four components, and recheck for the current leak.
I would venture a guess that none of these components are faulty, but that your current leak has to do with the Lojack install in some way.
It's worth noting that the "Fuel" fuse circuit is the only one that does NOT pass through the ignition switch in any way.
It makes sense that if someone were installing an alarm system (Lojack), on the SV, then they would tap the "Fuel" fuse circuit since it is ALWAYS hot. All the other fused circuits are powered via the ignition switch.
You're getting close.
Cheers!
