get my stock tach is still not working. sometimes its 1000 off and sometimes it jus barely works but i can see it move. can anyone help me solve the problem? its a 1993 VTEC non el cluster

 

bump. im dying to get this fixed lol.

 

mine doesnt work either...havent really looked into it though. most say the ignitor, some say its the cluster

 

can anyone help me with it?

 

 

check ur speed sensor....

 

i dont think the tach has the anyting to do with the speed sensor.

if you are registered at absoluteprelude, col_korn posted a really good thread about trouble shooting the tach with some great wiring diagrams. the signal runs from the sender unit in your dizzy (thats what was bad with mine) thru a blue wire to your tach.

get an after market tach for multimeter and test the signal at the "tach test connector" located near the top of the shock on the passenger side of the engine bay. its a little dead end, capped off, blue wire.


i took my old dizzy and swapped out the honda oem sender unit into my "distributor king" dizzy and my tach worked perfectly for the first time in a year. no problems since

 

ya mine sometimes bareky budges and sometimes is correct but exactly 1000rpm off.

 

can it be that the tach isnt gettin enough voltage?

 

*update* i havent seen it being only 1k off in a while. i searched for my p[roblem. no help

 

 

it is most likely the ICM (ignitor) freaking out.

If you have a friend to swap distributors with for a minute do it and see if it fixes the problem. If not you may have a bad ground, or the wire to the cluster is F'd

 

The wires are corroded and it's not getting the right voltage. Get to the wires and put new connectors on them, should fix your problem.

 

Or u can always buy an aftermarket tach.....autometer sells alot of different styles,and all are pretty reliable.Just an idea if all else fails.

 

i think its my needle not working right. is here anyway to fix a busted needle? i borrowed a friends aftermarket one and it worked perfect on my test wire so i know its the cluster and the needle is prelly messed up. can i replace or fix it?

 

Pm'ed
