Location: Chestertown, NY ( near Lake George) | Darren, positive gd 6v system, using a universal 6v coil, what terminal does the radio noise suppresor go ln? I say terminal marked negative, not the dist. side. Thanks, Shep

Location: Arizona | I vote with you. If the positive side of the battery is the ground, the "wire" from the noise suppressor would go to the negative terminal. The body of the noise suppressor would bolt to ground, which would in this case be the positive side. |

Location: West Jordan | That is a loaded question, it depends on what type of noise suppressor you are talking about, electronics and diode suppressed can only be installed one way, the way they were designed to be installed, pos or neg. Given the fact that it is 6 volt I will assume you are talking about the capacitor design.
On a simple capacitor (round tube single wire) design, in most cases, you install it the same way you would on a negative ground, the body or barrel mounts to engine or distributor mount (ground) and the wire mounts to the NON distributor trigger point of the coil.
The thing to keep in mind is there is a lot of RF noise generated by bad grounds, I would start there, and that is true on positive or negative ground. Other things that generate RF noise are bad plugs and wires, alternator rectifier that is failing, grounding problems in generator, and bad coil.
If you are generating too much noise and using a capacitor to control it, you will shorten the life of the capacitor. Also it is better to install the capacitor at the radio, from the factory they install it at the coil because it is easier to change if it fails.
Take an old walkman style tape player, don’t put a tape in but press play, with the headphones on move the tape player near the spark plug wire and coil, if you can hear the magnetic noise (alternator noise) in the headphones you have too much RF noise. Sometime you can see a slight glow from the plug wires on a dark night or you can get a simple RF spark plug wire tester for not too much money.

Location: Chestertown, NY ( near Lake George) | Darren, thanks that is how the oe coil was hooked up, will use the neg term. to hook the oe capacitor to. |
