I've been reading thru the archives but haven't found a solution to an issue I'm having with the RPM input for the 14point7 SLC PP2 unit. There's quite a bit of old material related to the Innovate products, but this product is relatively new to these boards and electrical isn't exactly my strong suit so I'm hoping someone can dumb things down for me...
I've tried tapping directly from the DME unit (pin 21), and directly off the tach (pin 2) and get similar results (screen shot below). I have confirmed the unit is configured with the correct multiplier. Wondering if this a ground issue, or a weak signal? Something else?
Any insight appreciated!
