Default RV12 Silent Hektik went silent

After more than 100 hrs of opertion, I'm doing my runnup last week and noted that my voltage and current indicators were showing low voltage and no charging activity. Back to the hangar. I have checked the connections to my SH regulator and they appear fine and the VREG indicator on the Skyview shows normal. Can this be that the VREG warning is off but the regulator is not behaving?

Thanks,
Mark

According to Van's electrical wiring diagram, there is no connection between the
voltage regulator and the Skyview. And there is no Skyview input labeled VREG.
Could the VREG indicator on your Skyview be for something else?

My version of the RV12 wiring diagram (RV-12_ULS_SV-AP-KNOB_04-06-18.pdf) has the SH 'warning' signal going from the regulator pin L to the EMS 37-pin connector pin 9. It was added when the Silent Hektik regulator option described on plans 46-19 rev 3.

Sounds like you can be the first one to "upgrade" to the new B&C Voltage regulator, approved by Van's this week.

Mark, You are right that the regulator has a connection to the Skyview.
But evidently there is a failure mode where the regulator has failed but tells the Skyview that it is OK.
I installed a John Deere AM101406 four years ago and it has not failed yet.
I mounted it with heat conductive paste and a shroud with air blast tube to keep it cool.
I also attached a thermocouple to it to monitor the temperature which gets up to about 150 degrees F
after takeoff when the battery is recharging. In cruise the regulator temperature drops to 130 - 135F.
The John Deere AM101406 is available on eBay for $19 with free shipping. I bought a spare one but haven't needed it yet.
Van's ELECTRICAL DRAWING has a B&C AVC1 voltage regulator.

I did same as Joe - John Deere AM101406 from eBay and mounted to a 3/16” aluminum sub-plate with thermal paste. Mounted on firewall shelf in original location with no add’l cooling air. Runs warm at ~ 170F. No problems for several hundred hours now. For comparison – top ignition CDI runs cooler at ~125F.

Silent Hektik VR failed at 185 hours of use. Upgraded to the B and C regulator. Interestingly, the temp indicator on the failed unit showed getting to 150 F but not to 160. I have the NACA scoop in the cowl. We’ll see how long the B and C VR lasts.

I followed Joe's mods back when - John Deere, blast tube, still going strong - back up in fly away bag, never have had to touch it. Knock on wood.

Has anyone been succesful with intalling the new B&C regulator in the original location on the shelf? .....Tom
