What is the correct inline fuse size for a 6 V. Radio and a
6 V. Heater in a 1946 P.U.?
Thanks.

Could be wrong but I don't believe either of those devices had a fuse in 1946. So if I am correct, there is no right answer. So, what is one to do? Do you have an amp meter? You could put it in line with the devices temporarily to measure the current and go from there. On the heater an ohmeter would work, but the radio will require the amp meter.
On the other hand, a fuse is used to protect the wire downstream from it. So if you know the gauge of the wires going to the devices you could use that as a guide.

I don't know about the radio but my 54 3100 has a 20 amp fuse on the heater. The Heater was still the old 6v setup when I bought it.

This radio bulletin shows 18amp for 1941-46 radio. It is not clear if that is car or truck (maybe they were the same).

Where is the radio fuse located? Another document shows 30amp for 1946 radio - fuse in steering mast.

I would suggest a 15 amp fuse for each. The radios always had fuses. They used to have a fuse holder for the radio that threaded directly on the Gen side of the ammeter. Inline fuses should work just fine.

Tim & Fred,
Thanks for your response. Instead of inline fuse I should have said fuse holder. It uses the Buss Glass fuses.
Tim,
This RADIO was used in the trucks.
Thanks again for your replies.
