Electrical problem

Greetings guys, I have a vf1000f 1984 and I just changed my solenoid starter but as soon as I ground my bike the 30 amp fuse keeps blowing.
Any help?
Thank you

 

Check your wire routing to make sure you aren't grounding out a main cable now that you've replaced the solenoid. You may have pinched a wire or found a chafe spot where it's now contacting the frame/ground.

 

Did you switch around the 2 large terminals ??

One is marked "M" and goes to the starter motor.

 

Nope, the diode should allow electrons to flow in one direction only.

 

So I think I got my problem, I'll change my diode tomorrow.I'll post it if it worked thank you guys

 

Or you might have switched the other 2 pairs of wires, 2 (Red) connecting to the main wiring harness through the main 30 amp fuse, and the other 2 (controlled by the START switch only to power the solenoid) on the terminals with the new part ? Polarity of wires could be wrong.

Somewhere, +12 VDC is contacting another wire or chassis ground where it shouldn't.
