Kam has spoken of doing a definitive ground wiring plan but it's a lot of work. I've seen her work as well as that of others on the vacuum distributor switch -- the HVAC control "thingy", it's sensational yet still a work in progress. As am I come to think of it. Am I asking for "unobtanium" here, I don't think I've ever seen this on a site; is it even possible?
      Work in progress? Put a fork in that HVAC diagram 'cuz it's as done as it's gonna get. Just need to put the link to it back on the site since it somehow got left out during the upgrade.

      FYI: The previously-provided link to the ground points changed; I just now updated it in my previous post: http://www.cabby-info.com/electrical.htm#Ground .

      FWIW, here is what the factory battery-to-frame-to-trans cable looks like:

      (disregard the cut section; I cut the cable rather than removing the air box/fuel distributor to get the cable out)

      If your ground cable(s) look like this:

      ...replace it/them! Consider putting the new cables inside wire looms to protect them from grease and other contaminants.

      I just got through replacing the main grounds on my Vanagon (they were disgusting), and cleaning up all other ground connections, as well as the alternator connections (van spent its life along the CA coast; every metal thing in it has a bit of corrosion on it). Took it for a drive yesterday and noticed that the dash lights are brighter! Moral of this story: Head to your local paint department, grab a wire brush or two and get to cleaning your electrical connections! (Disconnect battery first!)

      quick question for y'all: i have a 9a engine swapped in, now i still included the cowl to valve cover ground strap but im questioning myself as if its actually doing any good since the valve cover and head on a 16v is aluminum...

      so, is it serving a purpose? or should i just ground on steel, ie: block or trans?

      The head on an 8v is aluminum also....I'm keeping that ground strap.
      Aluminum conducts very well.

      They are behind the dash, if you take out the Fascia and the instrument cluster you will find them.

      The ground stars behind the dash are important. The main one next to the fuseblock has the fuel injection system grounds and the dash grounds on it. The failure of this ground is the main reason for your dash voltmeter reading poorly. When our cars were new this ground point was fine but over the years the heavy current flow combined with whatever leaks you might have from the rain tray make this connection to the frame/chassis somewhat poor. It's a pain to deal with as well. .I've polished the spades on mine and redone some of the connections. I've yet to remove the star and make sure the bolt-to-firewall connection is not corroded etc. If you want to simply make your interior voltmeter read more accurately run a separate ground for it. The voltage circuit it's on isn't overloaded, its the ground.

      How about the alternator ground? I have a spare alt for my wife's 83 cabby and it has a large ground strap coming from a threaded stud on the alt body (lower right side when looking at it positioned on the car with A/C. But the one in the car just has the spare threaded stud with no ground strap attached.

      You want to replaced the whole wire.

      why think we need to replace this one especially?
      mine is 35 years old from the factory (77-78) and seems to work fine
      checked ohms on it and was almost zero
      its just copper! copper is old as the universe right?!
      guess i can agree to coat it or get one that is already black rubber coated

      thanks for info guys

      I was dumb and bought 2 gauge wire instead of...4? for my batt to frame to tranny. Didn't end up replacing most wires as they seemed to be good once I cut off the parts that were corroded and green once I stripped them back. Replaced all of the terminals with gold plated ones and soldered them in. Does all old wiring carry more resistance, or have I accomplished something?

      Electrons travel the path of least resistance; corrosion, dirt, grime, tarnish = resistance. So, yes, you actually do accomplish something by cleaning and/or replacing electrical contacts/cables (both ground and power). Your electrical system is a little happier now.

      My Cab's ground cable was clean compared to my van's. Replaced the van's main cables, cleaned up most of the electrical connections in the engine bay (and elsewhere throughout the van), which resulted in brighter lights. Still need to clean the ECU and starter contacts.

      So im finally going to get around to doing this. But, dont know anything about wire/wiring can i get all the stuff i need to do this at the parts store? or can i just order a set of ground cables for cheap?


      1. Where do i get the flat braided wire?
      2. Brian in your picture of the battery ground it looks like you made your cable using two cables. one from battery to frame then frame to tranny.... or is this just different from digi to cis?
      3. Is this a simple as just buy wire and crimp ends on them?
      4. any one know off the top of there heads houw much and what gauge wire i should buy?

      sorry for the dumb questions i just want to make sure i do this right and not come up with new problems

      1. Where do i get the flat braided wire?
      A good Electric store, but you can use regular 14 ga wire, with crimp on connectors.

      2. Brian in your picture of the battery ground it looks like you made your cable using two cables. one from battery to frame then frame to tranny.... or is this just different from digi to cis?

      I used 2 off the shelf cables from my Auto parts store, one from the battery to the frame and one from the frame to the engine/tranny.

      3. Is this a simple as just buy wire and crimp ends on them?

      Yep.... 14Ga is good for the bonding wires.

      4. any one know off the top of there heads houw much and what gauge wire i should buy?
      A spool of wire from your AutoStore should be fine.

      The battery cables, you should remove and measure,, I think Kammy's site has the measurement.

      Oh okay great, simpler than i thought.

      I like your idea with the off-the shelf cables... looks really heavy duty

      When I bought the car the guy said it would die while turning... turns out the battery ground wasn't attached the frame... I'm thinking that it would make and break contact and short out when turning. I attached it now and it hasn't died on me yet (knock on wood)

      so...briano, you do good work here in the cabriolet forums
      why dont you ever hop over into the golf1 forums?
      thanks for your efforts!!

      and, i know not all of these grounds are present in all mk1
      so question is, why are there more in a cabriolet than a rabbit?

      is it advised to add more grounds to say...an early rabbit?


      i know for certain i dont have half of those grounds

      one last good note:
      a flat ground strap is extremely good even if it has surface corrosion
      they can be easily cleaned and painted to prevent further oxidation

      Because I don't do Golfs .... Well ok I have been driving mk1's since 1980 (Rabbit Diesel LS) owned off the showroom, and driven daily for 20 years.

      But as I am a dedicated Cabriolet driver... and it is friendlier here....

      Interesting... I am new Cabby owner as well, and a co-worker turned me to this site. Looks like I have a lot of work ahead of me So I did not know about the AC to Alt ground either... when I bought the car I was told the AC compressor did not work, so it is currently unplugged as if it plugged in, it will blow a fuse. Could this be a result of simply a bad ground then? Or is it more likely the AC compressor is actually done for and time for a new one?
