Hi Roger,
I hope all that flack from our 86 year old member blew over. There is a
clear need for a break out box but that's just not going to happen.
Front probing the 25 pin Digifant multiplug works just fine providing
you have the correct male pin adapters..... if not, female receptacle
damage is likely..........
As for your SECOND Digifant control Module failure in 2,500 miles, this
is unbelieveable ! Yoou need to send your failed DCM to the ECU gurus on
the list (Darryl ?) for analysis as to which external circuits caused
the damage.
For Vanagon diagnostics, a Fluke 83 is all that is needed for all the
Vanagon/Digifant level of electronics (THANK GOD !!!) Save all those
other high priced meters for the BMW 12 cylinder models !
Regards, JP
