Blown fuses, tip to diagnose

Here's the tip. Remove the blown fuse. Get a spare headlight and wire one of the filiments across the fuse clips temporarilly with jumper wires. Turn on the key and lights and hook a meter across the added headlight. The meter should read around 6v and be dimly lit as well as the lights the fuse protects lit dimly. If the light is full brightness there is a direct short somewhere, however this is doubtful because the short will normally be intermittent and not show up right away. Watch the meter or preferably have a meter that measures min/max with a beeper and start wiggling wires ect. When the short happens the meter reading will rise steeply. I wiggled all the wiring going in the handlebars ect and got nothing to change, then wiggled wiring in the headlight shell and the meter beeped and showed voltage had jumped to 9v. So I know my short is in the shell. So find the offending wire and all done with no more blown fuses. These AGX fuses are hard to find anymore and no use blowing anymore until the problem is fixed.

Iv'e found some sources for the fuse holders(blade style) if people are interested in this let me know and I'll post the web sites. This won't be a drop in modification and drilling and tapping might be required along with some wiring changes but as the man said finding the older fuses is going to be next to impossible soon.

You also can cut out the fuse clips and solder this $2 fuse holder in place. It also holds the new fuses. You need one for each fuse.

I know what you mean Ron, lost my tail light the other day and found a blown fuse. I work as a mechanic in a fully stocked repair facility so figured no problem. Surprise!, all we had was the longer fuses, was really surprised. I'll have to change over to blade type. Question is.... the regular blade fuses or the newer mini blades?? :blink:

The mini fuse blocks part numbers are:
#46090 for 4 fuses,#46091 for 6 fuses,#46092 for 8 fuses and #46093 for 10 fuses.
This company also sells all kinds of electrical devices like switches,wire,splices,heatshrink tubing,relays etc...
I'd imagine that www.delcity.net would also carry the ATO/ATC fuse holders along with the mini fuse holders.
The connections for the wire to the fuse blocks look like the standard 1/4" wide faston or quick connect type you push on the male part of the fuse block.
Make sure when wiring you use a high quality crimper as a poor crimp will get moisture and corrosion and resistance in it and the bike will run poorly if at all.

Thanks MFolks, that gives some options. I'm a litte worried about using the 46071 and 46091 'cause it's saying max 15 amps per slot and the main is a 20 amp fuse. Any thoughts? Looks like there's a heavy duty one available.
Noticed and was wondering the same thing! :blink:

The older glass type fuses can fail and look o.k. and the only good check is to remove them one at a time and again use a continuity checker(meter or continuity light) to determine the condition of the fuse.
