tach wiring question

Kegracing · 06-10-2011, 10:33 AM

I just installed one of these also, and have been fighting with it... I have the 12 volt running to it, with a normally closed button by tach. I push it, dropping the 12 volts as I stage. Should start recording - correct? The 12 volts do go back to it immediately (momentary break of voltage).

I am not getting recordings, and the shift light does not function correctly when it does not record.

Does the voltage have to drop for any certain amount of time?

What else could I be doing wrong? (loaded question I know... lol)

thanks,

Ken
