Voltage reads steady at 13.8 volts.  Amp drop is on the EIS unit, so the EFIS unit is not the cause.  Good idea on downloading data.

Subject: [LML] Problem with Fluctuating Amperage

 

Any ideas about what would cause my amperage to start fluctuating wildly about 5 minutes into a flight?

It starts out fine after takeoff at 15 amps and then goes to -50 amps for 30 seconds, and then gyrates between 5 amps and -50 amps for a minute and then goes back to normal. It repeats this sequence every 5 minutes.

My fuel gages also go down to zero during this episode and then back to normal.

Is my B&C LR3C Linear Regulator going bad?

(I'm getting these readings from my Grand Rapids EIS engine monitor. It's hooked up to a Grand Rapids EFIS Sport.)

Thanks for the help!
