Part 3 : MCI JH110B rebuild - Update June 27, 2016 We got spin!

I had tons of Molex connection issues and after cleaning and tweaking them endlessly we got Spin!

Also the RTZ works. Have yet to test storing locator points but RTZ was the main thing.




I placed a old trash real and the old head stack back on so the old tape would not gum up the new ones. I was worried about snapping the tape on first test. Also I have torque settings to do still.

The transport worked ok but seemed shaky, then after a few days of checking it the FF and RW stopped, the lifters still worked, and the joystick still RW and FW but the motors will not moved when pressing RW or FF.  So its all bad Molex connections.

So I took apart EVERY Molex connector, popped the pins out really, and reshaped and cleaned each pin to bring the connectors full back to life, about 200 pins I estimate. 6 hours later everything runs so much more solid!

Next is the Audio Drawer of DEATH!!!  That's right, no sound even passing on channel 1 and channel 2 shows -20db twitching.

Time to shuffle cards and see if I can find the bad boards then on to fixing 'em.
