Glass fuses for classic cars like Falcon, Mustang and other Fords.

Glass fuses for classic cars like Falcon, Mustang and other Fords.

Finding the right type of fuses for a 1960’s car has become increasingly challenging, not every glass fuse can meet specifications since there are a lot of different aplications.

Early fords uses AG series fuses, a prefix for  “all glass”. They vary in length, diameter and amperage rating, other popular type was the SFE, designed according to the Society of Fuse Engineers, all are 1/4 inch diameter, but introducing a variety in lenght according to ampere rating to ensure accurate fuse replacement.

The common specification for automotive fuses is voltage rating, 32 volts AC/DC, an important feature usually overlooked, using a different voltage rating may affect results.

For example, let's say we have two fuses, both rated at 1 Amp but made for dirrerent voltage ratings, one is 32V an the other is 120V, if we look at the filament of both fuses we will find there is a difference in filament thickness, may be it’s made from a different alloy, if we test those fuses in the same circuit, they will probably blow in different conditions, you can not expect both fuses to be interchangeable, they are safety devices and no feature should be ignored.

This is an application list for some classic Fords:
