[T2] Grounding Problem?

[David C Matthews]

Greetings,

Interesting electrical nuance:

     1- hop in my '71 Westy; notice the dome light is on (leave driver door
open)
     2- insert/turn the ignition key; get *nothing* from the starter
     3- notice the dome light is off

When I "reset" my bus by disconnecting/reconnecting the battery cable, I
can repeat the above sequence. Putting a meter on things, the battery looks
good both when measuring across the terminals and when measuring from + to
chassis.

However, when measuring from the starter + to ground (battery or chassis),
I get a good reading before trying to start (step 1), but nothing
afterwards (step 3).

Believe I may have either a bad ground from the transmission to chassis, or
a bad battery connection to the starter.

Thoughts?

David
