still no speedometer

So Ive been trying to get my speedometer to work on my 92 yj for a while, i saw a bunch of people had the same problem that i did so i checked the printed ribbon board and the ground was corroded so i jumped that, it didn't work so i checked the continuity if the speedometer wire and it was fine from the speed sensor to the gauge. when i pulled the gear out two of the gears were chipped at one corner rite next to each other. So my question is would the speedometer not work if two teeth on the gear are chipped

If the teeth are broken I'd replace the gear it could be stopping when it hits that spot. I may have a gear in my old transfer case if ya need one.

It should still work but be off a little.What you need to do is check with a volt meter . That speed sensor should produce ac voltage so jack up the vehicle and run the vehicle and clamp on both wires. Reading on the meter should go up with road speed. Then check to see if is getting to the computer.after that check to see if it comes out to the speedo head. I am sure if you go to your local repair shop and ask for a wire diagram. I'd not let me I can get you one.
