Does anyone out there knows what type of signal (square wave, sine wave TTL level) and what frequency drives the tachometer of the SIP Digital Speedo and Tach Part #50000400?
I am converting my '85 PX150 to electric and want to convert the tachometer into an ammeter.
I am having trouble with finding out what signal and frequency drives the tach, and the frequency difference per RPM.
Contacted KOSO here in the US, but they have no information on product manufactured in other countries and have not had any response as of yet from KOSO Europe.
Thanks in advance to anyone that can help!
