4.8v dc on C7 and 0.68v dc on C6 ..... Crystal ?   I measured  on the pin facing each other (inside pin) to GND.

Ok I'll ditch the fluke and keep using my other meter it's just your regular amp clamp with a auto ranging meter built in. I also tried my 9.99 Canadian tire meter .it also had similar readings as my amp clamp.  Except it reads open when  I test my can bus lines to GND.  (I'm assuming it can read over 20meg while my amp clamp does). 

I did get a new crystal and caps but didn't change them.. caps measured fine last time I tested them.   Did you test with just USB power?

As for the turbo , it was bought from a friend that upgraded to non vgt. I was told it worked fine and was tested before it was removed. But I have not seen it work in person.

Ya sorry I don't own a Fluke :(, just a basic meter who know's just how accurate it is.

Maybe the crystal got damaged as well ? I measure 1.8vdc and 1.5vdc on the inside of the caps leading to the crystal. Don't really know a decent way to test the crystal but it needs to be 16mhz.

What's the story on the turbo itself ? Working from a friend ? eBay ? Craigslist ?

yeah I unplugged  shield from arduino . I tried measuring with a different non RMS meter just to see . Not sure what meter your using , but there is a difference ... i'm little confused  now. with a regular meter i'm getting 15meg bettween r6 (com lead)  and either side of R3 (Red lead).
Testing Gnd(com lead) to to the can lines with Regular meter i get 30meg

With the fluke RMS, doing same test R6 to R3,  i get 18k and 6.4k  On R3 . (big difference)
I 'm also getting 8meg Gnd (com) to either can bus lines   

Also reversing leads gives me totally diff. readings.

7.54meg ohm from R6 to R3
8.26meg to the GND side of R3

still zero either Can L / H to GND, are you disconnected from the actuator while testing all this ? You might want to start to rule out some stuff, maybe disconnecting the shield from the Arduino if you haven't. etc

VR not getting hot anymore no. I changed both MCP IC's . U1 and U2 Only . I just re-measured with my Fluke 115 rms meter. and yeah i'm still getting 8meg ohms  from GND to R6 and 3.3 meg from R6 to R3. ... so yeah your assumption is right .  ;) 

It's a 351ve  actuator . I did have the matting connectors in my "big bin" of connectors . its wire according to your wiki pin out.

Hmm, isthe VR is it still heating up ??

Also what components did you replace on the board ? I'm not getting any measurements from R6 to GND or R6 to R3 respectively. If you still are something is still damaged.

Also is your actuator a 300VG or a regular 351VE ? 300VG's have the connection molded onto the housing, where the 351 is usually 4 wires out of the housing and a gray locking connector.

No it's not. :(  I have same voltage( 2.5v )out of the the can pins on controller.  And 2.56v and 2.40v on actuator.  I also notice the actuator doesn't have any resistance. ... shouldn't it have 60 ohms like the controller?  It does power up I can hear it "clicking" or doing something every time I cycle power.  But I do not have a spare actuator.  I dont like where this is going.....  any other suggestions?

Turbo not coming online ?
