I'm having trouble with my EIS 6000. Thinking about changing the 27k resistor, but I can't find one. My question is, can I put a 22k and a 5.5k in series instead?

 Thanks,

 Sam Marlow

   Sure . . . Or even consider

   a 50K potentiometer so that you

   can adjust it to exactly what's needed.

Can I get one at a local Radio Shack, and what exactly do I ask for?

Thanks,

Sam

Sam,  

   

What is the problem you are having with your EIS 6000?  If it is with the RPM indication, are you driving the RPM from the P-lead?  If so what resistor value are you currently using?  If you are using a resistor in the range required and it is not working you should call Grand Rapids.  There is a mod that is required on some 6000’s which calls for the removal of a resister internally.  It is a simple process and they can walk you through it or you could send it back assuming this is the issue.

It's puzzling, because it worked fine for 6 months, then the mag died. When I reinstalled the repaired mag, the tach started wondering, mostly at higher RPMs. 

 It's the 27k resistor, supplied by Grand Rapids. I sent a Demo log to G/R this morning, hope to here something soon.

 I did the mod on the circuit board, before first flight, if that's the one your referring to.

Sam,  

   

Yes that’sthe mod I was talking about.  Let me know what GRT says.
