Re: K6100 Focus

I will check the contact of the pin on the neck for focus again, but I know there isn't any corrosion there. I will see if I can make a hard wire connection to the pin even if it is temporary to test it.

If I remember correctly the actual socket for the focus pin mates with a contact in the plastic socket that connects to the focus wire. I had a 6100 that I had to hard wire that connection to get it to work. See if you can disassemble the connector and make sure the contacts are clean.
