Searching for a new or used "fuse block" for my Oliver 77...mine is broken. After doing some research _ I cannot find one! So Im searching for a "replacement fuse box" and all I see are 12v-24v fuse holders. My question is this- on a 6V system do I need 6v fuses? which I dont seem to find any of these; should I use the new style "push-in fuse block" and use 12v fuses? Or does it matter? Im confused:) Thanks.
 
The fuse will not know and will not care which voltage it is seeing. I sent you an e-mail too. Let me know if you do not receive it. J.

I thought my email was working but haven't seen one from you.
 
Call Korves Oliver. They have a single or double fuse holder for the older fleetlines and the four fuse holder for the late fleetlines. They are on their website in electrical parts. They take the old style fuse but are not exactly the same as the original but very functional. I used to get the same thing at our local Napa. You just need to find a good parts store that can look them up. Terminal Supply also has them.
 
I would recommend the push in spade type, and if there are only a few fuses, instead of a block, just use inline fuses.

They make them with a rubber cover to keep dirt and water out.

Just for general information, voltage does matter on fuses.

Automotive fuses are rated at 32v. That is what you will use on 6v.

Next up are 250v, then 600v, and above that is beyond my experience, but if you look at the element in a 32v fuse, and compare it to the element in a 250v, the 32v will be much bigger.

I'm sure there are a lot more lower and higher voltages, and many more in between. There are fast blow, slow blow, dual element, all kinds of specialty fuses.

"A fuse does not care if it is 6 volts or 120 volts"

On the contrary fuses DO have a voltage rating, but you will be OK with about any fuse (voltage-wise) in a 6 or 12 or 24 Volt system.

Fuses for higher voltages are constructed so the when the fusible part blows up and coats the inside of the fuse with metal they will not remain conductive, or sustain an internal arc.

Sometimes, fuses for higher voltages are physically LONGER, my have an inert arc quenching filling, or made of TOUGH ceramic.
 
Banjo, the voltage withstand rating and insulating capacity of a fuse assembly, be it used in a 6 or 12 or 24 volt application IS MUCH MUCH HIGHER THEN ANY OF THOSE VOLTAGES, so if its the correctly rated for X amps of AC or DC current it will work for of the voltages you asked about NO DIFFERENCE in 6 or 12 or 24........ Its more of a CURRENT sensing device then voltage, so as long as it can withstand the voltage difference its fine.

I was always told in arc flash class that the fuse voltage must be equal to or higher than the line voltage. I assume auto style fuse are rated for at least 24 volt.
 
I don't have any specs or data but Id "guess" their voltage withstand rating is even higher then 24 volts ???

Good plan, 6 or 12 or 24 volt Id guess any such fuses will work fine if correct amperage and physical size and fit

I've seen more then one fuse that was in an older car or truck read 120 volts on it bu was being used at 12 volts. I don't think voltage matters to a fuse unless maybe in the 300 plus volt range and even then I think it would not matter since a fuse blows due to over current not over voltage
