My 74 thing kept getting a low battery and I eventually took it to Adam at Kirkwood VW.
The generator and brake-indicator lights on the dash went out and then glowed when revving.
Adam checked and the generator was fine, but then he checked the Voltage regulator, and it was marginal. A new regulator and everything is fine./ No glowing lights on the dash and I feel that I can safely drive at night.
I have never seen a regulator die before, but this was the fix. The new regulator was unpainted shiny tin, labelled Bosch, made in Mexico, and apparently that is what they are selling now.
He did snip the wire that went to the diagnostic connector in the top of the engine compartment, on the old regulator.
Anybody ever used the diagnostic? _________________ 63 singlecab

I doubt that the diagnostic system made for our Things has been used anywhere since well before the turn of the century.
Those of us who remember the "advanced" diagnostic system of the '70's live in total amazement when we plug in our VCDS cable on a current VW.
The only drawback to removing the diagnostic receptacle (where keeping the car perfectly stock is not a consideration) is the necessity to disconnect the diagnostic wiring at its source; especially terminals 30, 15, 50. Nobody wants hot wires flopping around in the breeze. |

Does a "key" exist for the diagnostic plug? Never seen one that I can remember, but I am pretty oblivious about such things. Would think such would be out there somewhere. Should make troubleshooting that much easier, not that it isn't easy to start with.
In forty plus years of driving VW's, don't think I have ever so much as put a VOM or test light on the plug. |
