Hi all,
I'm new to the forum. I just bought a nice little '78 280Z. It's wonderful to own an S30 again. Back in my younger days I owned a '75, and it was the best car I ever owned. My ex made me sell it. :ogre: It's been 15 years, but I'm back behind the wheel of one of these beautiful machines.
Like another recent poster, I have an erratic tach. It doesn't go completely wonky, pegging both ends of the scales and such. Rather, it seems to read about half the correct RPMs, sometimes drifting up and down a bit -- sort of wandering around. Aside from that, the tach seems to be in nice condition.
The electronics geek in me recognizes that I don't have to spend hundreds for a new/used/reconditioned replacement tach. The meter movement is basically sound, so all that should be required is repairing/rebuilding the circuit board. It's probably some Schmidt trigger design -- something with a one-shot circuit. Basic stuff.
My question is this: With so many of these tachs failing, has anyone shared a schematic of the circuit with their fellow Z owners on the Internet? Helpful links? Or perhaps someone makes a replacement PC board? Any leads would be greatly appreciated.
On another matter, does anyone know where I could find a new fusible link block? One of mine has a broken mount.
Thanks!
Peace,
Sarah
