With Help from members of this forum I recently replaced the alternator and tensioner pulley on my wifes 2001 Accord EX-V6. When I was taking it for a test drive, I noticed that the tachometer was not working.

When the key is turned on the tachometer needle moves up to the zero mark, so it seems to have power.

There are no other warning lights, and the speedometer is working. I made sure that all of the warning lights are not burned out.

Any suggestions?

Thanks for your help!
