Hi.
I have a problem with a Vapour computer.
The computer doesn't read well the rpm. Normally when i go with high rpm and when i close the throttle are the bad readings.
I see too that if I press something in the light switch the rpm vary but only in high rpm.
I try with another digital tachometer only connecting the wire to the plug and this one read correctly the rpm.
I have connected the red power wire from the Vapour to the brown Lambretta wire and the black to ground to have light in the computer.
Someone can tell where is the problem?
Thanks!
