Title: Coil Wires and Horn Wires
Post by ThumperPaul on 06/27/24 at 11:59:44

Trying to install a tach.

On the coil, there is black/yellow and an orange/white wires. Which is the negative wire to connect the tach to? What the best way to tap into the wire? Piggyback spade connector? Solder?

On the horn, there is a black/blue strip and a black/red strip. Which is hot/positive? This is where I plan to get power for the tach.

Suggestions where to ground the tach?

Splicing into the coil wire and horn wire makes me a little nervous. I really don’t want to mess with those nice tight connectors.

Here's my modified wiring diagram -- I'd look into the connections but don't have the time right now. Just posting it here so you can access it

More power to you, Philly! No pun intended. This give me a headache just looking at it. All I can think is “why?”. What are you trying to accomplish with all this deletion? I can understand things like bypassing the clutch position sensor and side stand sensor, and maybe going to a manual decomp, but the other stuff I don’t get. For example, what do you have against a horn?

Coil wires. Which is negative?

I THINK the black is negative.

Regarding my own set up -- horn will get you shot here. Only lights I run are headlight and tail.

Nobody pays attention to signaling in Philly.

Horn wires. Which is hot/positive? Is black/red positive?

Thanks Philly, but I kinda need a “for sure” definitive answer on both.

I still don’t get it? Just don’t use ‘em. Why go thru the hassle and risk of deleting? Plus, if you ever sell it, it’ll hurt resale value in my opinion. Unless you plan to put it all back together. Sorry, I’m from the school of “if it ain’t broke, don’t fix it”.

Got it.

The "black and red" wire for the horn is 12v+.

The black wire on the coil is negative.

I replaced my handlebar switches with aftermarket stuff that required me to do some wiring and while I was at it removed all the stuff from the bars I don't want/use. So I have one micro switch in the RH side with kill/starter and that's it.

Since that stuff wasn't being used I also redid the wiring harness into a pretty simple, less cluttered cord essentially that runs the length of the frame from under the seat up to the bars.

This thing isn't being sold, I'm riding it till the doors fall off. I don't think id recommend these mods to anyone for any particular reason I'm just having fun.

That’s cool. I hope I didn’t offend you! I think I’ve mentioned before, I HATE ELECTRICAL! If I don’t have to mess with it, I don’t!

Awesome that you’re smart enough and brave enough to delve into it!

I also admire your commitment to the Savage! I keep running hot/cold on the bike, and dare I say, I think I prefer my Honda Shadow. I keep coming back to the Savage though for its light weight and being able to flick it around easier as I get older. It’s also easier for me to learn to wrench on and learn about things in general. I think I may have found a keeper in the S40 I have now though (a pretty clean unmolested 2006 with less than 6k miles when I got it 2 months ago). I’ve been talking to Fast650 and I’m going for the mostly stock looking sleeper.

I would not power up anything off the black/red horn wire. That wire gets it's power via the starter button aux contacts. The starter button aux contacts are prone to failure. They are wimpy, and can't handle the constant current flow to the headlight, running lights, and horn. Over time, they get fouled by water and road debris and start to arc and pit. You should hot up any accessories directly off the main switch outlet (orange). It's protected by a fuse and has the best chance of handling the increased current.

When you power up the tach off the black/red horn wire, you will eventually end up with an intermittent tach. As the aux contacts in the starter button start to crap out, the tach will start to do this crazy hula as it powers down and powers up. It will fool you into thinking the cheap tach is dead, when actually it's the cheap contacts in the starter button.
