Default electrical gremlins

So my sammy is more of a tinker with every now and then toy and gets driven around the property and neighborhood as a fun truck.

Now the issue is last time i drove it i was cruising around the neighborhood and it just stopped all together couldnt get it to crank at all.

Turns out i have some kind of short somewhere or some kind of electrical problem I think.

Reason i believe this is when i try and turn the key to on the ignition fuse blows.

I have charged the batter gotten new battery cables, grounded the body to frame and body to battery with the old cables just to make sure its not a bad ground issue.

after doing so i put a 30 amp fuse in and noticed the positive terminal getting warm. I have tried pulling the wires off the alternator and off the coil and both still blew the fuse.

I am at a loss idk where to check next or what to look for.

I honestly want to just start replacing ignition switch , starter, coil, these are the only things i really can relate with the ignition circuit.

PLEASE HELP.

Thanks.

Most of the circuits should have there own fuse, I can only recommend searching the main B/BL cable for a short to earth.
Can I assume your using a 30amp fuse in place of the original fuselink.

I tried putting a 30 amp fuse in place of the 15 amp to see if i could get anything and i got nothing. it ended up blowing the 30 amp as well. and both are in the original spot in the fuse panel under the driver side. Even with the 30 amp fuse I couldn't get the starter to jump across the solenoid, I couldn't get the dash lights on I can't even get the annoying buzzer to activate.

Where should i chase the wire from ? the fuse block? and what color is B/BL (black /blue)?
at the alternator i have a Black / white stripe wire. any info is greatly appreciated.

also just now when you said fusible link are you talking about something under the hood next to the battery cause that is something i did not know was there so i will have to check that tomorrow. I looked up fusible link issues and it sounds exactly like the problem im having. thanks so much I will let you know if that turns out to be the problem.

i do not have a fusible link next to the battery it has been replaced with a larger diameter wire...

looks like im not the first to have some sort of issue ...

i chased the larger wire to the white and yellow wire to the alternator, had a wire nut holding the three wires together. disconnected them and then connected the positive to the alternator nothing changed connected the positive to the white and yellow going back towards the fire wall and got the buzzer to cut on.

still no start and the wire was getting really warm... not good. disconnected them and wikll go back at a later date.

question is whatdoes the white with yellow stripe wire go to... and if that is getting warm where could it be failing.

The alternator may have been upgraded as this would require a larger cable to the battery.
I would never recommend fitting a larger fuse than stated as this can cause things to melt or ignite .
If the fuse blowing is the 15a IGN this circuit would have had a wire to the fuel solenoid, the weber does not use this so it should have been isolated.
