Eventually we will upgrade to a modern fuse box but in the meantime can anyone recommend places to locate specific size/amp glass fuses?
I have the owners manual so I can see the amp and approximate size needed.
local auto parts stores were no help. Nothing in LMC.com either.
The old glass tube fuses can be a challenge. Believe it or not, there are industry standard designations (3 letters) and it helps a ton if you know what to ask for. NAPA or any other parts chain store staff are not usually helpful unless you give them a number. The fuse rating isn't enough because there are different lengths which is usually the biggest problem. Ford dealers used to carry all the sizes you would need for your truck but I haven't bought one there in decades. Here is a link that shows the different fuse sizes Glass and Ceramic Tube Fuse Catalog Numbers. For example your radio fuse is a 7.5 Amp fuse and if my memory is correct it is 7/8 of an inch in length. If you go to the table you will find the catalog number is SFE-7-1/2 (or SFE-7.5). If you search on NAPA's site or most sites for SFE-7.5 you should be able to find it and then go to the store with their part number. They might have to order your fuse or bring it from a warehouse. Many parts counter employees don't know the ins and outs of glass fuses and they tend to direct you to what's hanging on the rack. Even googling SFE-7.5 will give you some hits. This applies to any fuse. The old fuse box in our trucks is okay if you know how/where to get the fuses. I keep a stock of most sizes and it actually doesn't cost too much to have some on hand. I hope this helps.
X2 most normal auto parts stores carry them. Have you tried a Farm and Ranch store like TSC (Tractor Supply Company), old school hardware store like Ace or Ture Value Hardware? Hit up your local BIG truck, truck stop.
“The bitterness of poor quality lingers long after the sweetness of low price is forgotten.” Just saying.
The problem I found is that unless you specifcally have it ordered some of the fuses you can only get 1 of from a multi pack for 5 bucks at O'Reily's, Autozone etc., Then you end up with a bunch of fuses you have no use for. You can get them at ACE or Do it Best but the mark up is insane. If you have time get I think you can get them on Digikey. This makes troubleshooting very difficult when you keep popping fuses. Could always stick a .22 shell in there...
Glass fuses are actually still largely used in Commercial low voltage boards for fire alarm, security panels, HVAC boards etc. Open your furnace up at home and I bet it'll have 2-3 on the board.
I gutted my fuse box as it was too rotten to save. I can mail you all of my glass fuses if you want as I have installed two blue sea panels.
When looking for a short get a breaker of the same size and wire it in while hunting for the short.
If you put a test light between the breaker and panel you can then look when it is sending power (light on) or it tripped (light off)
