Pick up cutting out

[Junior]

Gents,
I did a search, but after 6-7 pages of reading decided to ask instead. I soldered in some pups (dual hb's) a week ago, but yesterday the neck pup had barely if any ouput. I had this same problem with these exact pick ups in another guitar. But it happened a year and a half after I had put them in. The neck pup started to act up and have almost no output. I resoldered the neck pick up and it worked for a couple of months before doing the same thing.
I didn't use flux, so could the solder have some slight unseen oxidation that is causing the problem? Or could the solder (resin core) be breaking down? I bought the spool 4 years ago.

Thanks,
JC

it appears you have some corrosion going on there.
Always use flux.

When you resolder them, I would cut the old ends off and create new ones. Sometimes a wire will tarnish and even though its covered with solder its still not making a good connection. Since youve had this problem before with these pickups Id say start with freshly stripped leads.

Thanks for the tips guys. Being in a hurry (anxious) seems to be my down fall.
