Electical Guru Opinion Needed????
I'm in the final stage of completly rewiring my car and have a question regarding the grounding of the gauge lamps.
The Stewart Warner 2 5/8" AMP gauge has a stud on the back (3rd stud marked "Grd") that I have attached the ground wires (18 gage) from the 7 gauge lamps to. From the stud I have a 12 gage wire going to the chassis ground. Is there any reason this would not be acceptable?
Thanks.........Rick

Rick ,
A # 12 wire will carry all the instrument lights you care to connect,including a small christmas tree . But if it were me i would wire my lamps in series accross the gauges and ground from the ends to keep from stacking eight terminals.

I'd recommend running the ground wires to a stud behind the dash somewhere, not on the gauge. The setup you're talking about will work, but I wouldn't want all that current on the back of the gauge looking for a ground if your #12 failed for some reason. I don't know what your dash material is. If it's aluminum, then there shouldn't be a problem even then.
I have to respectfully disagree, in personal preference only, to wiring the grounds all together, inseperably (if indeed, I understood Karl correctly). I very much like to be able to replace wires one at a time, and want failure modes to be independant. Of course, I have been worked with a lot of vintage Lucas, and this might have made me unreasonably paranoid!
I also like to add a couple of cigarette lighter sockets up under the dash out of sight. Wal-Mart sells them, and they come in very handy at times.

Thanks guys! Keep the thoughts coming.........
The sole reason for using the existing stud was to keep the back of the aluminum panel "clean" in lieu of having a mass of spagetti behind the dash, and it was a centralized location. I like the idea of a removable power socket for cell phone. Maybe a compact plug in lieu of a cigarette lighter socket.

Steve/Rick,
I would never power source instruments in series for just the reasons you mentioned ,it makes trouble shooting just that much more complicated and i wouldnt want the monitors for my engine to be that vulnerable. That said ,what I was suggesting was to NOT stack 7 or 8 terminal ends on the back of a meter ,but to jumper just the lamps and ground to the chassis from each end for some redundancy. of course a ground lead for each lamp does make for easy trouble shooting ,but does not offer the "backup" ground lead
on the other hand my common sense says I should probably defer to any of the Kirkhams when it comes to things Cobra

Rick, I wired mine as kobrakarl suggested, should a light go bad, it has no effect on the others.
