My first engine start went great last weekend -- except there was no RPM indication.
I checked the wire continuity from the P-mag to the input (pin 7) on the VM-1000C and it was good. I then tried getting the tach information from the other P-mag, but that didn't work either.
Tech support at E-mag told me to try putting a 0.47 microfarad capacitor in series in the tach line because they had heard that the VM-1000C was a little "sensitive". That didn't work either.
Then I tried hooking up pin 9 on the VM-1000C to ground (shouldn't be necessary according to the manual and their tech support), but that didn't work either.
So next week I'm going to obtain an oscilloscope and a pulse generator. I'll try testing the input to the VM-1000C and the output from the P-mag independently to determine which one is causing the problem.
Is anyone else running this combination? Does anyone else have any ideas I could try?
Thanks.
