Fortunately I had a working board and I used a DMM on the diode scale (for the
audible) and attached one lead to the cap in question and I waltzed the other
lead around the board on every point until I found a zero ohm connection that
did not exist on the damaged board. Running an external jumper fixed it.

Ingenious. I'll remember that. Thanks.

I had a Samsung multi layer board that was working but quit after I
replaced a typical leaded electrolytic that was vented a bit. Top and
bottom connections fine but the middle layer was not. Several reheats did
not fix it.

Well, you got lucky. You'd want to find the closest point that same net
came to another through-hole. If that net didn't come out to another hole
nearby, the long wire would somewhat defeat the purpose of the cap. If in a
high frequency circuit like a switching regulator, it might not work.

The problem is not the cost of ONE connector, but the distributors
make you buy 160 pieces minimum order! That does get expensive.


As a private individual repairing my own kit I have met that problem
too. If you can find a sympathetic salesperson you could try asking for
a "sample"...

Some of that has aslways been a sore spot with me. The companies should be
required to sell any parts to an individual to do their own repair.
I went with a man to help him pick up some boat motor parts. A man off the
street wanted to buy some small part of about $ 20. They would not sell it
to him. So we bought the part and then sold it to him. If not for us, he
would have had a hard time getting that part.

I have called some companies and received small parts with no problem.
Needed a special transistor for a $ 1500 radio. Called Icom and ordered two
of them and the postage and parts was about $ 5. No rip off at all from
them.

Wow, fair pricing and avialable parts? Glad I just got an Icom radio. Just
tore it apart too- the construction is excellent- reminds me of late 1990s
Motorola radios in the attention to detail and ease of service.
