Hello:

I'm an electrical engineer in PSE's facility services group and don't 
have the opportunity much of asking electrical questions.  I like to fix 
things and found mikrocontroller.net with my topic of interest but it 
isn't in English.  I wish I had the English version of that topic that 
discussed the Toshiba T2295A chip.

I don't see rules for postings so kindly let me know if this appropriate 
for this forum/web site.

The T2295A chip drives the tachometer meter on a scooter that is 37 
years old.  The meter works with, say, 1.25 VDC at it passing 12.5 ma, 
so the meter's internal resistance is 100 ohms.  This is with the meter 
out of the circuit.  Meter works as a voltmeter and is fully functional, 
though labeled in RPM.

Looking back into the PCB and capacitor (driving the meter) I see 200 
kohm, but the meter always has 0 VDC in sitsu.

Is there discussion on mikrocontroller.net on how it works, expected 
voltages at the ZIP-9 chip leads, back sheets in English as 
alldatasheets.com doesn't list it?

The PCB schematic comes from mikrocontroller.net.

Later:  You know, I think I got it working.  I saw VCC and IN and they 
were swapped.  Probably all these years by the original equipment 
manufacturer.  Looking at the schematic I got from mikrocontrollers.net 
in a language I didn't understand, yet seeing those two words/symbols on 
the drawing helped me just minutes ago.  Swapped the yellow with the 
black wires to the Honda Flush tachometer.
