fried fuse board?

[Gazza M]

trying to get to the bottom of a problem i'm having with my indicator fuse blowing. originally thought it was small amounts of moisture getting in the connectors to the junction box - cleaned that up and the problem seemed to disappear.

following the ridiculous rain we've had over the past few weeks, the bike seemed to do the same thing! I've taken the junction box out this time as i suspect the o-ring seals have seen better days.

anyway, took the box apart, the seals could do with a bit of silicone grease, but i'm more worried about the PCB itself! the channel the indicator fuse runs to is a bit shitty, wondering if this is useable still or whether to find a new box/pcb.

shittiness ringed....

i don't have a multimeter at the moment to check the connectivity, can do that tomorrow i think...
