On the end caps you should read SAE15 10 or 5. Plus another number 250 or 330 is the speed of the fuse in milli seconds. There are no slow blo blade type since the internal circuitry will protect the device itself. If it is a slow blo the fillement will be wrapped around a center rod or a large piece of solder that delays opening. A circuit breaker will have two pieces of meter filliments side by side and will close back when it cools.
Now for the lesson in fusing!!!
The fuse that blows may be nowhere near the problem.
It WILL be the weakest on in the circuit however.
In most recent system designs all devices are shunted and the fuse is placed on each leg that leads out bound at the amp closest to the Power supply.Because a short on any leg is going to draw the highest current at the P/S before it travels to the point of the short. Barring lighting strikes and accidental cuts if a short develops it usually means a device is starting to go bad and you will probably see humbars past the suspect device.
