Voltage Regulator Failure

Good thought, Mike.  Ross, is this a UL/ULS engine, or an iS?

If it's an iS, there's another possibility that might explain the minimal load capacity: loss of one phase of the stator feed.  Perhaps a pin/socket backed out of a connector body or one rectifier diode failed open?

Thanks guys

2016 912 ULS,

No strobes running, but charging for IPad, Stratus, and lithium iron batt.

Going to do the testing suggested with a multi meter and check connections.

CARMO CMM5005.

Fitting straight forward BE SURE THAT ALL CONNECTIONS ARE GOOD & TIGHT. I left my Capacitor in place , not connected.

Have about 2 Hobbs hrs now. Works great. Long may it do so.

Performance (sorry, from imperfect memory)

Directly after start; 14 V 10 amps

Pre T-O Runup; 14.2 V 3 amps. Temperature 40C

Some time later in Cruise: 14.2 V 1 amp. Temperature 36C (Note; The VR has a dedicated cool air supply)
