Hi all.

I want to buy a set of fuses of various amps. I can only get single ones from David Silver. Any suggestions?

IIRC they are just standard 20mm glass fuses. You can buy them anywhere.

What do you advise Matron. Assuming it doesn't hurt.

Dear Dr. It will not hurt  ;D ;D ;D The fuses are 30mm in length (If you have a standard fuse box fitted to your CB400/4) I would prescribe either buying a box set of multi Amp fuses, although most unlikely to contain 7 Amp but may contain 8 Amp which will be fine, or buy a pack of 10 of both 7 Amp and 15 Amp from China via Ebay at about a £1 for a bag of 10 delivered. Change PRN.

OR UK based : Lower price for multiples

when rebuilding my 400f from various boxes i found the grotty fuse box. i had two choices, a new one  from DSS or a blade version from Hondaman in the U.S. , in fact they are the same price even with shipping from the U.S. ( import duty to pay though!)  The blade fuses are readily available just about everywhere

I use domestic fuses which fit perfectly... in the 15A slot I use a 13A and have had no problems.

Does it matter that these fuses which you have mentioned are for 250v??

Good question although that is just the operating voltage that the fuse can withstand in operation.
Technically speaking, fuses blow when they get hot and are rated as such and such an amperage depending on the heat that will blow the fuse for any given amperage. So that the thinner the fuse wire the less heat it can withstand and therefore less amps.

Matters more with switches wether ac or dc as dc sparks heavier

Anyone know why automotive fuses, the type fitted to the early Hondas have a wide foil like element, rather than the single wire?

Just as an aside to the 'fuses' discussion, last year I had a problem with the main fuse failing every now and again, which obviously led to leaving you at the roadside with a dead bike! Replaced fuse, everything worked fine with no obvious signs of a short anywhere. This even led an occasion when I had the fuse fail, had run out of spares, was 6 miles from home, and it was starting to rain. In a desperate attempt to just be able to get home, the only thing I had in my pocket was a screwdriver 'bit' set. Yes. the bits are a perfect fit in the fuse holder. Started bike, switched on everything possible, and looked for smoke! Got home safely, spoke to a vehicle electrician, who asked to see the old fuse which I still had. It had not 'blown' in the centre of the fuse element, which signifies a short, but had let go at one of the end caps. He informed me that this is caused by it struggling to draw current. We removed the fuse holder, after disconnecting the battery!, and lo and behold, when we seperated the plastic plug behind, all the terminals inside were a lovely green colour. Purchased a cheap set of jewellers' files, 45 minutes patiently cleaning up each spade and connector, problem solved. Plastic plug is now totally encased in insulating tape to try and keep elements at bay. I have written all this drivel thinking that if you are going to all the trouble of messing about with the fuses, spend a few extra minutes and check that 'orrible plug.

To keep it from failing due to vibrations...
