Good to know. I have always preferred soldering to crimps and taps, but my past has been in RF and electronics in a non-vibrating environment. I seem to have discounted the havoc that vibration could wreak on the individual wires right at the point where they are held stiff by the solder.

Keep the circuit breakers, but consider replacing with new if you can find the exact specs for the ones you want to replace. Those connections look pretty nasty....but it's been a lot of years.

 

I have used soldered connections on bikes for decades with no problems. The trick is to relieve the stress at the joint. Support the wires and the joint wont vibrate and break. They only use the crimp connections because it is cheaper and quicker to do. Not everyone has access to a soldering iron let alone how to properly use one!

 

If you decide to go with fuses I recommend this stye fuse holder.
They are much more water proof than the glass fuse holders and use the blade style fuses.



They make several different styles of resetable curcuit breakers, these have a small button on the side to reset them manually.



However, if you have the room I like these.



If you do decide to go with fuses and want to neaten thing up you could us a fuse panel.

 

what are the wires for , they could be voltage regulators for the instrument panel gauges also . you really need a wiring \\digram and know what they are first
could be breakers could be regulator for the gauges they look about the same

 

Those are circuit breakers and can be replaced by fuses. But you have to fuse them correctly by amperage. You need to see a wiring schematic.

 

I did the same conversion on my bike.those are your circuit breakers.don't bypass them.i left mine under the nacel.then I eventually moved them to under the left side cover.
