Wiring for Tach?
10/18/05 at 19:53:34

Help!! I picked up a HD Tach but I need help identifying one wire, (or wiring location), my 86 Savage.

Can anyone tell me how to identify which is the NEGATIVE wire on my coil?

One coil wire is Orange with White stripes which is connected to the wide blade terminal fo the coil. The other wire is Black with Yellow stripes and is connected to the narrow blade terminal of the coil.
Thanks

Does anyone know, how to connect a Harley Davidson FXR tacho to my Suzuki Savage wiring? Which wires I am to connect... I don't know a single one of them...

Hi Michiel,

I recently bought 2 Tachometers to install them on my Savage. I bought a tach from the Auto store before I found a HD tach on e-bay. The wiring for each Tachometer is only slightly different. I will try to list the details below.

Wiring for HD tachometer, (clone of HD tach made in China??).

RED wire – Connect to 12 Volt source powered when ignition is “on”
BLUE Wire – to lamp on, (12 volt DC source to power the light inside the tach).
BLACK Wire – Connect to FRAME Ground).
GREEN WIRE – Connect to negative terminal of coil

Wiring for Car Tachometer, (Sunpro Super tach, Made in China).

RED wire – Connect to 12 Volt source powered when ignition is “on”
WHITE Wire – to lamp on, (12 volt DC source to power the light inside the tach).
BLACK Wire – Connect to FRAME Ground).
GREEN WIRE – Connect to negative terminal of coil

You will find it handy to have a wiring diagram of your Savage to identify which of the bike’s wires you need to splice into.

I hope that this helps.

Dale

Reply #7 - 01/19/06 at 08:12:01 since this one raised up it's head - it would be interesting to know how the car tach worked out - because of a spark on each up stroke I guess a car tach would see this as a single fire(like a car) two cylinder - so if was set to a 4 banger seems to me it would report 1/2 the actual rpms - anyone tried?

A tach was something i always expected to see on a motorcycle so there is the habit thing. Then the thumper runs so smoothly in 4th i have to listen closely to the engine to figure if i am back in 5th- it makes a distinctive "meshing"noise in 5th. I have found myslef barreling along in 4th wasting fuel quite happily after i was forced to shift down for traffic. A simple rpm/speed visual helps remind you which gear you are in.

Reply #14 - 01/20/06 at 15:55:51 I've been using a cheepo small engine tachometer on my savage as a tuning tool. It's nice to see how a rejet or different muffler changes the shift points. Don't like using the seat of the pants to decide if the mod works cause my seat is way too big to feel any difference .
