Re: [DML] Ground Bus

The only way that could help is if the car is having problems with its bulkhead bolt to frame wire (the 6 gauge wire that runs from behind the coil to underneath the coolant expansion tank), and even then the effect would be minimal because the radio bracket is only connected to the foremost console junction by a single 16 gauge wire -- there is no other ground connection to the radio bracket, and the radio bracket is of course electrically isolated from the frame.

Speaking of which: everything from the rear bulkhead forward (including everything in back of the car grounded via the bulkhead connectors) is totally dependent upon the bulkhead bolt to frame wire mentioned above. Degradation in it is almost as bad as degradation of the frame to battery wire.

My bus ties the bulkhead bolt into the battery via another path (a larger gauge path) so that wire is rendered moot. I've left it in place of course, but if it ever degrades or fails, I will never even know it because the car will still function electrically normally.

Anyway, I 100% assure you the instrument cluster and binnacle are grounded at that hard to see junction. Every owner who has looked for it found it eventually. Perhaps Harold could take a picture of it on his bare wiring harness.

Any owner can easily trace the wires on his or her radio bracket to see that they only go to the radio itself and a couple of noise reduction capacitors, and of course one small gauge wire out. Even the A/C panel illumination bulbs which sit in the radio bracket are not grounded via the radio bracket.

It still makes me wonder why on most of the cars that I have added a ground wire from the radio bracket to the frame have gotten improved results on the dashboard (lights/gages), but I have no reason to doubt his findings.  Adding that ground may give some other ground path between the harness and the frame a lower path of resistance that has not been considered??  Either way, it would be hard to dispute that adding an actual large gage copper wire from the ground splice direct to the battery would have a negative impact...  which brings me to my initial question-  Has anyone found fault with this?
