Bike is a 75 CB360t. I was messing around with wiring for tail light/turn signals, re-routing & generally just cleaning up the rats nest that was there. I ran a 10a fuse from the kohler rectifier/regulator & I always remove the fuse when I work on wiring. I wasn't even messing with the kohler but when I put the fuse back in it today it blew instantly. What do I need to be looking for to fix this? I've ran this kohler unit since last summer without issue.
