David,
You could have a regulator going bad, but I’d look for a loose ground first. This won’t be easy, but is more likely than a bad regulator. Also, if you don’t find and fix the problem very quickly, you will likely fry the regulator…and possibly other equipment as well.

My two cents…

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!
