Wiring diagram main harness 92yamaha fzr 600

MY main relay keeps blowing I believe because of a short in the harness but I can't find it. IT doesn't blow straight away but doesn't take long either.I have replaced the fuse numerous times. What should I try next?

Isolate the problem by removing all small fuses, then replace main fuse with an ammeter that will measure 40 amps or more. Replace small fuses till ammeter shows a larger current draw. If this doesn't show problem, the problem is in the starter or charging circuit. Let me know what you find.

Exactly what can blow the main fuse

Hi, Anonymous you have a dead short which is usually the easiest to find. Using a test light connected to the hot side of the blown fuse holder, start probing the wire leaving the fuse holder about an inch away the test light should illuminate, keep probing towards the ignition switch until the test light no longer illuminates you are now very close to the short.

My yamaha genisis fzr 600 wont start now and backfires when i try to start it

Hi, Anonymous and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Severely discharged or damaged battery, you need 12.5 volts or better and be able to pass a load test if necessary.
8. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
9. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
10.. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
11. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2, TPS, ETP, IAC,or BAS).
12. Faulty neutral, clutch lever, or kickstand safety switch.
13. Faulty fuel pump fuse or relay.
14. Security alarm needs a reset.
