Title: Wiring for Tach? Post by fla-shadow on 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 8) |

Title: Re: Wiring for Tach? Post by Michiel Pielkenrood on 10/19/05 at 07:50:57 I hope you'll allow me to use your topic for a moment (instead of starting a whole new topic...) 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... :-/ |

Title: Re: Wiring for Tach? Post by fla-shadow on 10/20/05 at 16:08:10 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 bikes wires you need to splice into. I hope that this helps.

Title: Re: Wiring for Tach? Post by Reelthing on 10/20/05 at 20:36:16 Should not need to splice a wire - the twin tail spade connectors will push on the savage coil connects and just find a ground like the mount for the horn |

Title: Re: Wiring for Tach? Post by Reelthing on 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? |

Title: Re: Wiring for Tach? Post by sluggo on 01/19/06 at 15:13:18 i ask this oftern. WHY. a tack on a thumper are like tits on a boar hog. now if you want to make it an appearance mod, great. as a preformance mod, doesn't cut the muster. |

Title: Re: Wiring for Tach? Post by conchscooter on 01/20/06 at 11:34:25 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. |

Title: Re: Wiring for Tach? Post by 650-rider on 01/20/06 at 14:22:47 Has anyone tried the tachometer or speedometer from JC Whitney? They are reasonably priced. CHROMED TACHOMETER (http://www.jcwhitney.com/autoparts/Product/showCustom-0/Pr-p_Product.CATENTRY_ID:2008924/c-10111/Nty-1/p-2008924/Ntx-mode+matchallpartial/N-10111/tf-Browse/s-10101/Ntk-AllTextSearchGroup?Ntt=tachometer) Edited for a cleaner link to allow the page to format properly.

Title: Re: Wiring for Tach? Post by Ed_L. on 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 ;D. |

Title: Re: Wiring for Tach? Post by Reelthing on 01/20/06 at 16:23:59 Ed - you using one of those tinytachs? |

Title: Re: Wiring for Tach? Post by theikeman on 01/21/06 at 20:59:52 The Tachometers above from JC Whitney are "mechanical" drive, will not work on a savage. FYI Ike |

Title: Re: Wiring for Tach? Post by Fat Bastard on 02/24/06 at 08:42:43 Ok I bought a Tach.. and I'm going to put it on... I got the tank off. I had to take the petthingy completly off.. maybe next time I will use more force to try to yank the tank off without taking the petthing off.. Ok.. I have seen to different explanation of wiring.. 1.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 2.on the Barrons tach you have 4 wires - green for the trigger wire - this connects to the top connector of the coil, a red and a blue wire - one is for the tach light(blue one I think) and the other the one is for + battery connection (red i think) connect both of these to the bottom connector of the coil which is the hot wire, the other wire is black and this goes to ground - I just connected this to one of the bolts that holds the coil to the frame. On mine there is no blue wire (see pic) but to black ones. http://i7.photobucket.com/albums/y269/virago125/tach.jpg Can anyone give me a hint.. so I don't mess this up... |

Title: Re: Wiring for Tach? Post by Reelthing on 02/24/06 at 09:59:02 I can't find a queston - what color wires do you have? is it a barons? Never mind I see the question - so the #2 wire you have in the picture is black as well as the #1 ? |
|
Title: Re: Wiring for Tach? Post by Reelthing on 02/24/06 at 10:21:02 Ok what I would do if this tach landed in my lap without any instructions - I'd expect the red and green to follow normal uses - red is hot and green is trigger - I would bolt the tach down and hook up the red and green wires - now we need to figure out which black wire is ground and which is power for the bulb - the best guess would be the heavy #1 wire is the ground wire and the smaller #2 running inside the cord with the other two is the bulb power wire. But to change it from just a WAG to a SWAG - take a multimeter set to DC and check for any voltage on either of these both postive and negitive with the key on - if neither are hot and the small black wire is and open circuit the odds of hurting anything are remote and I'd ground the #1 wire and put current to small black #2 wire. |

Title: Re: Wiring for Tach? Post by Fat Bastard on 02/24/06 at 11:52:08 Yes I think the thick black wire#1 is the earth.. and as you say the red and green are probably "normal". I have a "Regulated Power Supply" where I can switch between 3, 5, 6, 9, 12 or 13.8 volts.. but I get no light when I connect wire #1 to - and #2 to + but the light is not important to me... so I'll connect the red and the green wire and then try to figur out the other to... but there is also a fifth wire .. a blue one wich comes out of the tach where the black #1 comes out .. it connects to the tach with a screw... maybe that is somekind of "earth 2" or backup.. thanks for the answer.. |

Title: Re: Wiring for Tach? Post by Savage_Rob on 02/24/06 at 13:23:53 Don't cut the red wire... |

Title: Re: Wiring for Tach? Post by Fat Bastard on 02/24/06 at 14:07:37 I won't cut the red wire.. I found a test site where my tach is. same part number. http://www.motorcyclecruiser.com/accessoriesandgear/tachs/ it says there that. Custom Chrome Mini-Tachometer " In order to utilize the internal instrument light, the blue and black wires exiting different holes in the tach housing must be connected to the power and the ground, respectively. Since the wires exit from different places on the tachometer, we recommend shrinkwrapping them together to clean up the appearance." here they continue to speak of this blue wire.. but here I understand that wire#1 is for the internal light and the wire#2 is the ground for the hole thing. |

Title: Re: Wiring for Tach? Post by Reelthing on 02/24/06 at 17:11:23 Neat little puzzle - so it just has the light seperate from tach board altogether. Red/Green normal ground the little back wire and then you have a working tach. Power the large black and blue wires at the tach head for the light bulb. Is that what you ended up with? |
|
Title: Re: Wiring for Tach? Post by Fat Bastard on 02/25/06 at 01:50:47 jebb.. I have put the tach on and the green wire goes to the top connector on the coil where the Black/Yellow wire is.. The red wire goes to the bottom connector with the orange/white wire and the black wire goes to ground.. but the thick black/blue wire for the light is to short to go anywere.. I have to get me some extension on it.... |
|
Title: Re: Wiring for Tach? Post by Curz on 02/25/06 at 12:20:07 I would say that the thick black is probably 12 power for the tach light. and the thick blue is ground for the light. Just mount it (will provide the ground) and run the thick black lead into the headlight (not too far away) and then the tach will light whenever the headlight is on. |

Title: Re: Wiring for Tach? Post by Fat Bastard on 02/25/06 at 12:40:09 I did not think of that..... Note to self... Headlight.... Thanks. |

Title: Re: Wiring for Tach? Post by Fat Bastard on 04/09/06 at 00:49:07 An Update.. I did connect the tach and it was no problem. there is no flicker so the connections must be in order. I have not yet connected the light. It's not a problem seeing on the tach without the light. I think it looks nice.. I'll just have to remember to look at it when I'm riding... I still shift by the ear/feeling. http://i7.photobucket.com/albums/y269/virago125/t2.jpg http://i7.photobucket.com/albums/y269/virago125/t1.jpg http://i7.photobucket.com/albums/y269/virago125/t3.jpg |
