my cathode lighting inverter fuse blew, i'm trying to replace it but the circuit doesn't specify the fuse size..anybody know what size/rate the fuses usually are for dual 12 cathode lights...BTW 'm running it from a 12v supply

thanks

It will be marked on the fuse itself.

I brought it to a shop and that's what they said too, but when I showed it to them they can't tell either. it's one of those glass fuses.....

On the metal housing you will see very faint markings, this will indicate the voltage and the amperage. You may need some good light, and a magnifying lens if it is worn down.

If in doubt, rub a lead pencil over the etched markings and it will come out clearer, for you to see.

it doesn't have any metal housing, it's all glass...the size is about a rice grain if this helps...

You're going to have to post up what this fuse looks like. I have never seen a fuse as small as a rice grain, and certainly not one without two metal end caps.

How would the current flow, without metal contacts at the end to complete the circuit???

i can't seem to get my camera working so I'll do it with more description..anyway it actually resembles a reed switch but only it's a fuse, so how the current flows is just like how it does on a I.E. resistor. the fuse is soldered in placed instead of any regular fuse holders/clips. hope this helps..

thanks

What you have discribed could be a ceramic cylinder fuse. The only other thing that sounds familar to what you have there is a thermofuse.

But I doubt it . . .
