Connector at the tachometer

[georgesgiralt]

Hello !
I've a problem with the wiring of the speedo tachometer as the cabling has been abused by an improper routing.
Any idea :
How could I remove the pins to solder /repair wires ?
Where I can get new pins /connector ?
How could I avoid problems in the future ?
Thanks a lot for your help !

I've worked on these things a bunch, so should be able to picture what you're asking about pretty easily. But I'm not.

First off, I think it's the Tachometer that has all the wiring. Not the speedo. Correct?

The speedo only has one bulb for illumination purposes. So I doubt it's that one.

There's a connector from the wiring harness and pins on the circuit board inside the gauge. I don't have one here to look at - but as I recall, the pins are part of the circuit board and make connections through the board. I don't think you're going to be removing the pins!

Are the pins bent?

Did something happen to the traces leading from the pins?

It may be necessary to source another circuit board - but I'm just stabbing in the dark since I don't really understand the problem.

Sorry, my mistake ! I was referring to the TACHO !
I would like to replace/repair/ mend the wiring from the loom connecting (with the round plug) on the tacho printed circuit.
The plug has female pins on a white plastic housing, the tacho's pin being male.

I haven't removed the pins/wires from this particular connector, but I have on quite a few others on the bike .

The pins have a spring tab, that prevents the wire from backing out of the connector when the the two halves are mated up .

The method that I have used, is to get a small diameter tube or electrical butt splice that just fits over the pin, push the wire from the backside of the connector to get the spring tab free, push the tube or whatever you have onto the pin to compress the tab, then you should be able to remove the wire and pin from the connector .

Parts for the connector are not available, unless to have a spare to rob parts from .

That's a neat method Bob.  I usually faff around with a jewelers screwdriver with variable success.

They sell a pin extractor at Radio Shack but any electronics supply house should carry them in a variety of sizes. Works well, press it down on the pin to compress the spring lock tabs, then use the internal plunger to eject the pin.
