Fuse holder...6v vs 12v?

Postby Dale Finch » Thu Nov 12, 2020 4:05 pm

I have a 6v '55 Cub that I am working on, and one item that is missing is the fuse holder. In its place is a little toggle switch, which I think a PO installed as a light switch (but haven't confirmed), bypassing the original light switch, which is there but not connected to anything.

I need to order a radiator from TM Tractor, so am adding things to that order, hopefully saving on shipping. TM has the 6v and the 12v fuse holders listed. The 12v is $6, but the 6v is $23.89 !!! As far as I know, the only differences are the wires are already attached to the 6v, and MAYBE the contacts are a little beefier on it as well? Plus the nuts that hold them in place are different...same diameter? Can anyone give me a good reason to NOT use a "12v" (less expensive) fuse holder on my 6v system?

Also, while I have you, and because I am whupped and lazy, anyone remember the amperage of the fuse...20A?

No reason I can think of. The 12v is available from the supplier hence the cheaper price. The 6v one has been modified, probably to match what came on the original 6v Cub. If you're not looking for an absolute direct replacement, I'd go with the 12v one.

Go with the 12 volt fuse holder. I'm pretty sure you can add the pigtails and terminal ends for a lot less than the price difference.

Fuse size. Front, rear lights, any additional appliances? 20 amps would be a good start.
I have an excuse. CRS.

Thanks, guys! I do like an original look, but I believe THAT detail I can easily overlook for the price difference! :lol: :beer:

Hi,
Below is a page from the 1955 Cub operator's manual, showing the fuse size for the 6 volt system.
It is in the specifications section. It says 20 amps.
If you are just reading through the page, the maximum engine RPM is for Cubs up to serial number 192113, which was during 1955.
IH increased the RPM slightly after that number. The next manual says 2016 RPM. :)
