It seems the last couple/three times out my tach will have a mind of it's own.

If it acts up it is only at start up and will be 3 or 4 thousand optimistic with very little movement from then on regardless of real engine speed.

Original battery and has been on a float charger during the winter.

Any ideas are welcome, thanks.
 
I can't make time this weekend to even look at it but I'll check out those wires and I'll keep you in mind skip thanks.
 
Are you sure? I haven't checked, but the new TuneBoy programme can make the tacho do different things such as showing throttle position.
Rather clever that! - If they come up with a way to make the speedo/tacho needles visible at night - Then I'll be impressed. :)

If I find a cheap instrumentation loom or the loom connector block (I don't like hacking original bits) - I'll be fitting decent "clocks".
 
Coil input wires are always worth checking ANYWAY.. looked at mine after firing issues, the input leads were VERY slack!! take them off & crimp up with pliers.
