Marshall TSL fuses ?

[Valvehead]

ok here we go -

with standby off (non run mode) amp powered off, measuring the W7 post--wire unhooked from OT ...

i get open.


fuse removed , standby on /run , w7 post to gnd = open.

w8/w13 wires pulled , clipped the pcb connectors together , fuse does NOT blow.

same thing above with plugging in W7 = fuse does NOT blow .

IT WAS THE SWITCH !

amp is fired up and works / sounds great ! ( SO FAR )

so how can the sw cause that ? Its plastic--looks fine , i tested the terminals to ground -they are ok . ??
