Thunderbull charger transfromer thermal fuse

[GolfMechanic]

I'm working on 2 thunderbull 48V chargers. I found that the primary winding (120VAC side) on both transformers have no continuity. I took one of the transformers out of the charger and poked around a little bit (cutting into the black plastic/paper covering that hides the windings) to find the "disconnect" is where a fuse is. According to a diagram that a local golf cart shop gave me, there should be a 135C thermal fuse in line with the primary winding (between the board and the transformer). I'm pretty sure it's this fuse. Anyone know where I could find a replacement fuse. I know (according to the diagram) it should be rated for 135C but I don't know the amperage rating. Any info would be helpful. There are no markings on the fuse (or at least are unlegible).

Thanks
