As far as I can figure out the actual tacho clock is the same for all years anyway,funny how my tacho developed the exact same fault as yours and we got the replacement tacho from the same place!
Yeah, I stand corrected... apologises for the confusion...
Ahhhh, that makes sense now if it comes off a Garda bike.
No problem Martin and thanks for your help,the speedo on my bike reads mph on the outside and kph on the inside in smaller numbers,I'm always learning something new about this bike,hopefully thread will assist someone else in the future.
The Guards have stopped using ST's as far as I know,the use Deauville's and Fjr's now and maybe some Bmw. I don't think they ever stepped up to ST1300's,but I could be wrong.
Glad to hear the problem is gone, enjoy the ride if the weather permits
Thanks,of course now the bike is fixed and it starts raining!! Murphy's LawGlad to hear the problem is gone, enjoy the ride if the weather permits
Lucky you... over here it could be snowing in a couple of weeks...
Then you can go skiing while we get lashed out of it by westerly atlantic gales and rain
You might rethink...
Amen to that,I spent most of last Sunday on forest roads with the transalp,far from the madding crowd.
...why we ride and that... ;-)
My 1999 ST1100A tach quit working recently. After I disassembled the dash to get at the input wires to the Tach I measured ~4 vac with the engine running so I knew the pusler output to the Tachometer was working. After removing the tach module I used an ohm meter across the red and black wires and measured <1 ohm, pretty much a dead short. Unsoldering the red lead from the circuit board and measuring the resistance across the movement assembly I measured 50 ohms and the needle would return to 0 if I manually moved the needle, so I assumed the movement was OK. Unsoldering the black lead and disassembling the circuit board from the plastic housing I measured the resistance again across the red/black solder points and read <1 ohm, Electrolytic capacitors may fail over time so I suspected the 1000uf @ 6.3 VDC electrolytic capacitor was defective. Unsoldering and testing the electrolytic capacitor confirmed it was shorted. I could not find a suitable 1000uf @ 6.3 VDC electrolytic capacitor replacement locally. Physically the radial lead capacitor needs to be short enough to fit in the housing so higher voltage capacitors could not be used. As luck would have it I had an old PC video card that had the same physical dimension electrolytic capacitor on it except it was 1500 uf @ 6.3 vdc. After replacing the capacitor and reassembling the tach module I tested it by clip leading to the pulser output leads and the tach was working again. After a 1000 mile trip it is still working OK.Broc, I'm not sure if this helps, took some pictures of my "slow to respond" tacho with the plastic backing on & removed.
It has a small pcb with some components on it(x2 capacitors, x2 resistors, x1 variable resistor, x1 diode & x1 IC - power inductor according to my friend google)
Only solder connections to the board are the 2wires(red & black)
There's some sort of a small coil/spring device attaching the tacho needle to the unit itself, unable to remove that though.
