  • Distributor Grounding

    RX

    If you are like me, I'm getting tired of having the metal grounding roller on the distributor eat up the bottom of the tube. I do not like the thing, but you need it for scoring, and I like to put a plastic eccentric in their place. I do this so I can level off the front end of the distributor and have the pins go off flat and not at an angle. What I'm doing now, is to use the static brush from the 82-90 pin wheel. I forgot the part number right now. If someone wants it I'll post it later. They are not cheap, but I like them. When I order them I usually get 4 at a time.

    EXCELLENT Felix! I have been preaching about that for years! All you have to do is point a static meter at a distrubutor and you'll see that they can build up a LOT of static (many in excess of 25K volts) and that just ain't EVER good! Those nylon rollers can be a zapper....I like the looks of this mod!

      **** it is a good thing i have 8230. Now I know the reason why nobody posts on 30,s is that they are running while your working on "newer machines", Just a joke no one to talk to on 8230,s Later Chief

        Nice mod Felix.

        Any issues with brush marks?
        Any rate probably less than the drag marks from the steel roller.
        Please.....follow the instructions!!

            Is this the same as a ground wire being installed on the bounce plate to the support bracket?

              Re: Distributor Grounding

              I've seen something similar... it used a piece of copper braid (like grounding braid or desoldering braid) in a loop that just touched the rail. It was attached to the front yoke (just about where the brush is in the above pic) by a screw and a small washer.

              Those things can definitely build up a charge... in the winter when the air is dry in the building, I have seen sparks jump from the rods to the yoke that were 1/4" long or more.

                Re: Distributor Grounding

                I've always wondered how the static from the dizzy or the carpet could get to the scorer (like the girl dinosaurs in Jurassic Park - nature finds a way?).

                It's a nice looking mod, though I'd worry about the wire bending all the time (hit by pins, rags, etc). G's mention of the copper braid sounds more robust.

                Thanks Doc, and Felix.

                Cheers,
                Andrew.

                    Wonder who Rick got that idea from??

                    Been using those brushes for years...even posted it about 6 years ago. Still running good, no problems with marking the tubes.

                    Funny thing: if you put a continuity meter from the carriage tube to the frame, you'll find that with AMF's steel roller, there is much less contact than with the brush.

                    Another idea: McMaster-Carr, as well as other suppliers, I'm sure, carries static dissipative brushes that can be mounted across the distributor belt (no need for contact), within 1/4". You can drill a small hole in the main casting to mount this piece under the belt.

                      Grounding, shmounding - You could save almost a hundred dollars by just having the pinchasers continuously walk across the back and touch each distributor all night.

                          When we got our Accu Score system in '89, they supplied us with a metal roller wheel for the single flat wheel on the dist.
                          AMF told us to double check our bounce plate straps.

                            I get zapped every time i do carpets - on the ones we don't have carpet grounding straps on (well derr di$$head). I have a system that stops my ears being zapped - mainly ends up through my leg or shoulder.

                            Never got a shock from cleaning the dizzy belts, though.

                              I cant speak for all the Californians, but I have never needed the grounding straps on pit boards or the metal roller on dists. Never been Zapped or seen sparks from the distrubutor. Scoring has never had ill effects from non-grounding.
