Indeed, with the "old" British system of auto fuses, the blow rating was given.

All modern fuses are marked with their continuous ratings, so either a 15 or 20A continuous fuse will be the nearest equivalent the "35A" blow (17A contiuous) fuse normally specified for many British bikes.

Sometimes these British fuses are marked with both ratings:

Any fuses you are likely to find these days such as the blade fuses you showed will be identified by their continuous ratings:

Light Blue = 15A (Cont.)
Yellow = 20A (Cont.)

So I should not use the 35A blade fuse which is a continuous and replace with a 15A or 20A of the same type?

There isn't any "35A" bade fuse as far as I know, but the "30A" blade fuse (Lt. Green) will blow at 60A, which is far more than the 35A blow original fuse.
 
Only if you can fix it right there. Better to ride home with the lights flashing. I even made it home once with my engine cutting in and out. They are more expensive and it's up to the owner, but most of my bikes have breakers.

What kind of breakers do you use? Pics?
 
I may have some pix at home. Usually I use what we called aircraft circuit breakers when I was trained in the local plane shop many years ago. I used them in Grehound busses and trucks for cross country work, they come standard in trucks and busses now. My favorite if there is room is screw on terminals, we used to junk busses after 3,000,000 miles and tehy would still be good.The screw ons can easily last 30 years with no service in near maximum load conditions.
On my Norton I used the new compact slide on terminal type since the use it gets is not critical, and the slide on connectors should be good for ten years or so. I'll probably be dead after that. Most auto parts stores carry them now but the clerks are often uniformed about them.
 
This is from an article I did a while back on types of fuse and breaker we commonly use in my industry. Forgive the Locomotive fuse.
The small breaker with slide ons is available in most auto parts stores in 20 and 30 amp.

hey Cookie, if you can get a part number from Napa or the like that would be great.

I like this idea, maybe I give a test for the season, but is it a problem that breaker looks longer than the seat? where the hell do I keep it out of site?

(no funny comments plz) LOL

That little breaker is about the size of a quarter, but maybe five times as thick. My local NAPA closed but next week I'll try to go to one in another city and get a number for you. What do you want, 20 or 30 amp? I have the small 20 amp on my Norton and it is tucked into Velcro on the roof of my battery box. If I had a starter I'd use a 30 amp.
We have Kragen Auto parts here as the common store, oh, Pep Boys too, and I forget the name of the other store.
