Hi All,
Not sure if this belongs in Engines or Electrical. It's a little of both. So I'll ask the magneto-specific questions here.
The Problem:
I have 2, Slick magnetos.
During run-up, When I check the left mag, my EFIS shows the RPM. When I go back to BOTH and then to the right mag, the RPM is displayed for an instant, then counts down to zero in less than 2 seconds and then the value is replaced with "---" on the display.
I have a TruTrak EFIS and EDM module.
Ok so I've been studying up on Magnetos, wiring, the EFIS etc.
My Question:
When you check the right mag, you ground out the left and it no longer produces a spark. So then you read the RPM running on the right mag only.
Is the rpm information that comes off the P-Lead on the left mag still there and readable even though you've grounded out that P-Lead? I assume it is as there is only one pin input for Tachomer in the EDM (Engine Data Module) connector.
thanks
