Christian Thanks for your post and insight. I will try adjusting the set-point later today when I get time to work on it. Currently it is at 85C. The inverter is room temperature. There is no heat in it at all. My real questions are: 1. what is causing the fault? 2. is my board populated correctly? ...

So maybe I have another incorrect component. I took a picture and was comparing components to the BOM and I noticed R21 wasn't a match. According to the BOM it is supposed to be 10 ohms. I haven't found it on the schematic yet. The resisters in question are near the top of the attached photo where t...

TMPHSMAX Hi All. I've been trying to get my inverter to do something other then have some LEDs blink. My motor would sometimes jog or engage for a split second in MANUAL MODE. With nothing hooked up other than 12v and GND I get fault TMPHSMAX. Looking at spot values TMPHS it is reading 85.43 degrees...

Asking $650 for the inverter/converter and $450 for the motor. The motor is heavy and bulky so I would prefer ...

Thanks!

Nice word Dusty! I'm planning to do about the same thing with my Beetle only with a Prius inverter. Do you have a picture of the adapter plate?
