Slow tachometer problem. LHD AE86.
Having trouble with my tachometer.

When I crank the engine - it shows RPMs. But when I stop cranking it still shows last RPMs and then slooooooowly drops even below zero.

I asked my clubmates at ae86-club.ru and they said that on RHD dashboard tacho quickly drops below zero when ignition off. And when you turn ignition on it jumps up to zero.

Need ideas.

Could this be solved by changing the capacitor in circuit of tacho power supply?
