2000 LTA500F Blows fuse

[Guest VINCH]

When i connect my battery the 30a fuse on the starter relay blows

I checked the starter cable and starter ALL GOOD

I did note however when the B/W small wire from ground terminal of battery is disconnected

And I connect the Large cables no fuse blown

This is on a 2000 Suzuki LTA500F Quadmaster 500

Bottom line every time I connect the battery cables I blow the 30a fuse thus no power to anything at all. Wiring all looks intact I exposed almost all of the wiring harness tracing the small B/W wire from the grounded side of the battery

could it be the CDI unit or rectifier

I did replace the starter relay that is fused 30a as the original relay was blown

Any thoughts are greatly appreciated

probably a short ... check wires at handlebars for wear and thru frame rail at gas tank/seat area. possibly a bad ground connection on frame ...

Turned out the Red wired off the top of the ignition relay had a rub through in it. Oddly enough up by the key switch. Also has some debris at the contact points in the key ignition contacts. I also had to replace the ignition relay again. All is fixed and it runs like a champ again thanks for the help
