30 Amp Fuse Keeps blowing out

[TURBO200R4]

So got a problem with my 2006 rocket, put a relocation switch in used for 6months now every so often will start and idle before blows the ignition fuse 30amp. Replace put in new one goes straight away without starting

how long have you owned the rocket?
have you replied to other sites on face book?
are we talking about the big 30 amp or the small 30 amp?
you can get a 30 amp breaker fuse for testing purpose.
if small 30 amp what works after the fuse blows?
