Tachometer on CB550SC Not Working gerpena

I replaced my key ignition switch with an aftermarket one, and though
the bike now starts fine, now the tachometer does not work.

Also, the front panel lighting is different-- for instance my nuetral
light turns on if i try to start the bike in gear but it wont stay lit
if i shift the bike to neutral. This did not happen before.
The overdrive light used to come on when i ran the bike in 6th, but it
doesnt anymore.

The speedometer is working fine however.

Advice? Suggestions?

How about going to a bike wrecker and see if you can get an OEM part...

would have done so happily, but i was unable to find one. why should it matter anyway, i thought the ignition system was merely a switch? thats all i changed....

Did you reattach everything behind the gauge cluster, it could be that you didnt tighten everything up correctly?

Get a service manual, check the wires that you may have unplugged.
a neutral light is usually part of the starting circuit. Does the bike start
with the bike in gear and not in neutral?.
