Default Sportster tachometer wiring question

I want to adapt a Japanese electronic tachometer, the type which came stock on ‘70’s and ‘80’s Sportsters , to my ‘77 fxe. I see a lot of these nos gauges for sale on eBay and the tach’s have four wires: red, white, orange, and pink. Can anyone tell me where these wires go , ie which go to ground, signal, ignition, etc?

well, you probably will have to find a nos fx tach as they receive the signal diff than the sportsters. you could adapt the sportster tach however.
i will check my library for the wiring, but the signal was taken off the alternator and not the ignition.
this was kindly brought out in another post from DR. DICK

better to send a schematic, will pm one first chance.

From 99484-85, pages from end of manual with wire diagrams for 1981-on

white... high beam
red... light bulb
pink... signal from electronic ignition
orange... 12 volt

I would have guessed that the signal, even though in has a different source, would be the same; so a sportster tach would work on an FX. I could be wrong of course. I have not seen the posts from DD on this topic.

ok, on your year model, they went to the newer charge system and done away with the special regulator.
the tach is hooked up like the sportster.
on your machine, power comes from the accessory circuit breaker orange wire.
the pink wire ties into the coil on the points side (lead going to the points or electronic module if you installed it)
if you can post the exact tach you will be using it would help.

on yours, the tach light is tied to the speedo light with black wire tied to the orange wire. another black wire is to ground and it to ties to the speedo light.
do you have the schematic?

the clarification DD made was in a discussion on the charge system actually.
there was a member that was trying to hook up a tach to the older style system which outputs from the regulator that has a diff output. my 1974 fxe had that system.

These are the two styles that I used. I stayed with the newest of the two mostly because the glass was cleaner. Wiring is Pink= trigger from coil. Orange =power. Black =ground These tachs work really well and very steady needle action

Thank you--very helpful! Basically, I want to move my gauges off of the dual handlebar bracket and move them to the top mounts on the forks. I saw all of these NOS Sportster gauges on Ebay and was wondering if those gauges would work on my '77 fxe. On my current stock gauges, it seems that the signal and ipower wires are the same--ie orange to ignition and pink to the coil.

I have been watching this thread and have used the search regarding electronic tachs on sportsters.....somewhat the opposite of what Doc 308 is doing.

I have a 77 FXE tach that I want to use on my 77 XLH

It is suggested not to use the the switched / ignition side of the coil to power the tach....is this given, that it will not give a correct reading ?.....why ?

It appears to be a convenient place to pick up power.

Two wires to the tach ...ground, and a light bulb.

Thank you, Carlos

I don’t know why it didn’t work I thought ok just run the two wires up through the loom. It would be fine for a few miles and then the needle would start bouncing all over. I asked on another forum and it was suggested that I try a different power source so I went into the nacelle and tapped in there. It’s worked great since. Whether it was the fact that I went to the coil for power or had the two wires side by side in the loom which I doubt after it wouldn’t work right

a big problem is that when the magnetic field collapses, it induces counter EMF back into the primary side of the coil, this will actually ring a few times before the next saturation is called for.
