pls help!~installing aftermarket tachometer!
i am sure that i connected every wire correctly.
and i set the cylinder setting to 4 b4 i install it to my civic. the tachometer light is working, but the needle doesn't move when i start my engine or the car is running. when i try to set the shift light..the needle moving with no problem. i tried to step my gas padal very hard...i saw the needle moved up once and hit the shift light point..(i only saw it once ) and one time, i did this again..the needle doesnt move, but the shift light is on. the problem that i guess is: the tachometer wire that connect to my civic tach signal wire is not long enough.. so i used 2 wires to connect it to make it longer. (tach wire+1 wire+1 wire+civic blue tach signal wire) do u think thats why it will make the tach signal become very weak???????????????????? thx~pls help!~ |
naw, if you soldered the connections, the drop in resistance should be minimal so the signal won't be weak.
It seems to me like you have a bad connection somewhere... is the tach new or used? |
it is a brand new..one..
|
does the shift light come on EVERY time you rev it?
if it does, I'm betting the farm on not having a power connection to the tach. Why not break out the multimeter?? |
if you want someone with an electronics back ground to have a look at it PM me ..... if your a TCC member I'll do it for free...

Sounds like bad connection..
Or defective hardware.. |
I mean specifically does the shift light come on every time you hit the set shift point in the RPM range? again, do you have a multimeter?

Originally posted by 94EG6HB If no multimeter use your tongue to verify voltage.. It should hurt more as you rev.. i am not sure...it hit to the shift point or not..coz the needle is not moving...i just try to step the gas padal very hard sometimes..and the shift light is on sometimes.. |

my offer still stands.....

1. turn on your multimeter :p
2. set it to read a range for about 12 V DC 3. verify that you've set it correctly by going right to the battery and check volts there 4. go into the cabin and ground the black probe to a screw in the dashboard FRAME 5. use the red probe and connect it to the SIGNAL wire on the tach 6. observe the voltage on the multimeter - there should be SOME voltage that varies as you rev your motor 7. report back! |

either/or.....
anyways if your unsure what your doing it's safer to take it to someone that does. |

i install lots of tachs and its probally a very simple thing you just over looked |
And the verdict is?
|
fixed???????
