Title: Fuse blows when powered on [resolved]
Post by: Bakemono on August 22, 2020, 06:31:21 PM
It passes all the resistance checks but when I plug it in and turn it on the fuse blows. I've rechecked the wiring 3 times now and had a friend check over it as well and it doesn't appear that anything is out of place. I did do the 5/6/10 revision if that has anything to do with it? Not really sure where to go from here. I've attached some pictures below, maybe I missed something

I see leads touching around terminal 19 that shouldn't be.

Those diodes between 18 and 20 and 18 and 21 are not oriented correctly

I re-soldered the diodes between 18 and 20 and 18 and 21 and also made sure that leads that weren't supposed to be touching, aren't. I turned it on and the fuse blew again unfortunately. I rechecked the resistances afterwards and they all seem to measure correctly.

I've attached a picture of how that area looks now, the rest remains unchanged from the previous pictures I've sent.

Could you show us the other side of the terminal strip with the UF4007 diodes?

I changed the revision (connected it to 22L now) and also changed the fuse from a .5A to a 1A fuse and it works now! Thank you both for the help.
