Having trouble getting a good ground on my BN6

[bighealeysource]

Hey all,
Starting to put my BN6 back together and having trouble
getting a good ground on it. I purchased it about 80%
through a 100% total restoration project so now having to
install the interior,chrome, grill, lights,windshield,etc.
In the process of starting it back up, the positive cable
from the battery was connected to the sheet metal on the
back of the trunk wall. The cut off switch is not installed
at this time. I couldn't get a spark or pump so started
doing a check of all the systems and turned out to be the
bad ground. If I ground to the trans mount, rear end, shocks
with a jumper cable and then to the + post everything works.
Will not get a ground to any of the sheet metal on the
inner panels even if I find an unpainted spot. Any ideas
on where I should ground the cable to ? Or maybe I am
missing something that y'all might know about ?
Thanks,
Mike

One (1) of the rear shock mount bolts would be a good ground, if not concours...

Likely the reason you're not grounded through the body, is too much/too good of a paint job throughout the body.

You do have the ground strap between the engine and chassis (near the bellhousing on rh frame rail)?

Hey Randy,
Good question - I believe there is a heavy blue coated cable between the
chassis and bellhousing but will double check. That could be the problem !!!
Thanks,
Mike

The ground strap for the battery normally goes on the bolt circled in the photo. That's about the only thing I did that was original back there. :smirk:

Oh fer gosh sakes! I thought BN6s were made <span style="font-style: italic">after</span> the invention of interchangeable parts.
