Howdy everyone! I have a quick question regarding a fusible link in my 1975 C20 Scottsdale. From the 12v distribution block in the engine compartment,there is a fusible link that goes to the orange wire that feeds the Heater Blower Motor High Speed Relay. The plastic casing of the fusible link is broken and I need to replace it. However I need to know the amperage of fuse to use. 20amp? 30? Smaller, bigger? Could someone please help me!

Are you talking about the 30A inline fuse?

Is this what you are calling a fusible link? My high speed fan stopped working. The fuse and holder was burnt. Replaced holder and fuse and works fine. I believe it is a 30 amp glass fuse.

Yes that's exactly what I needed to know. 30amp fuse, perfect! Thank you fellas!

On my truck the barrel-shaped fuse holder must have developed some corrosion/resistance, and whenever I put the blower on high it would heat up and start melting the fuse holder. I decided to purchase a 30 amp blade fuse holder and fuse, and spliced it in as a replacement.
