    Looking for info on the small grounding wire to the fender.
    My 72 GS had one and I purchased new battery wires from M&H Electric and the new ground didn't have the little wire to the fender.
    I also ordered a set for my 70 GS (top post style) and it didn't have a little grounding wire.

    My 70 should not have the grounding strap but my 72 should?
    Need some help.

    Thanks

    my '72 gs has the extra wire to the fender (14 gauge?)
    My '70 chevelle had the extra wire to the fender. That wire actually smoked and I had to replace the whole cable purchased from the dealer. A short somewhere caused it to fail.

    You got a 71 battery cable which did not have the ground. Call them back and tell them you want one with the ground. Also if the positive cable is black with a red end send that back as well. It should be all red. They get that wrong as well.

    You can never have too many grounds I have been told by better mechanics than me.

    I have a question about 71 battery cables that i was hoping one of you can answer for me. I had asked Santa to bring me a set of battery cables for my 71. My wife told me M&H had said they would be able to send the negative right away but the positive would be delayed because of something to do with the plastic block that the cable passes through down along the oil pan rail. She had no idea what they were talking about and i have yet to call them back to get the details. What are the options for this? I am assuming they will want me to send my block in to have the cable made up, have any of you had this come up?

    Tom, This comes up here all the time. Give them a call. They most likely want your block. Cut the old cable and try to pull it out. If you cannot get it out maybe they can. When I have done them I just cut the block open and pull out the old and then snap the new cable into the groove I cutout. When put in the metal tray it does not show anyway. Better to do it the right way however.

    Tom, Also not sure if you are using spring ring or side post cables depending on build date of your car but if you use side posts make sure you insist on an all red positive cable not a black cable with just a red end. They may try and tell you that the blue print shows for a black cable with a red end but they are wrong. That style was used on later models even though it has the same part number.

    Thanks for the information Dave. My car is a Sept 1970 build so i have the top post cables and I am ordering the spring ring cables. I got through to M&H shortly after i posted and as you mention they want the block shipped to them before they make up the cable. Unfortunately the car is buried in storage for the time being. I'll have to ship it to them in the spring and wait a little while they make up the cables.

    Tom, good luck with the cable. Maybe you could find a used block here and get a jump start on the project?

    Thats a good idea , I'll keep an eye out for one, in fact i should probably comb through the stash and see if i already own one...

    Tom, send the plastic block to M&H and they will install it on your new positive cable. They have done mine in the past and do real nice work. Be careful with the plastic blocks, they are usually very brittle from the heat and oil.
