Alright so last night I ventured out in the Trabi during the day and had a pleasant drive out to the parents house. car ran well enough and no problems. Then the sun went down... I am talking full on Jeykell and Hyde kind of stuff. The drive home was eventful to say the least. Everything started off just fine. The car started just fine and we pulled out on the road with lights on low beam. made it up to fourth gear about 1/4 mile for the parents drive way and within 10-15 seconds of being in 4th gear the car dies. Lights are still lit but engine is dead. Car will not restart by dropping into lower gear and letting off clutch. I don't like using this method so I only tried once and then came to complete stop. car took a minute or 2 to restart. She fired back up and away we went. got her back into 4th gear about 1/2 mile from first stop and the same thing happens again. This was my drive home for a good 35-40 minutes. After the 7th time the car died on me I finally gave up and called the wife to bring the trailer and haul the Trabi home. I did notice that the red warning light on the speedo seemed to glow a little as the speed increased while driving. It never came on full bright unless the engine died. and while stopped with the lights on it usually did not come on but once I would take off or rev the engine while stopped on the side of the road it would glow a little as the revs increased. I was able to make it to a church parking lot while waiting on my wife to bring the trailer. Out of curiosity I let the car continue to run. I checked the fan belt while running and everything was there and seemed fine. I drove around in circles a few times while waiting, with the lights off as the parking lot was lit. Car seemed to drive around and run just fine in the parking lot. Idle was fine. Cut-off and restart was fine. The only difference was the lights were off. We loaded the car and took it home. After unloading I started it back up and backed into the garage with no fuss at all. and that was the end of my night. So my question is does everybody drive at night on a regular basis with no problems? I know a lot of you have upgraded to the 12v system and it is more reliable when it come to electronics like lights. I am still running a 6v and would like to keep it that way (original). Am I resigned to a day time driver? What can I do? First thought is to replace the dynamo but I would like to have it tested first to see if maybe its not creating enough power to send back to the battery. Sorry for the long post. I was pretty aggravated last night with the car. For it to run so well in the day and with no lights on and then to run so poorly with the lights is frustrating. Also the battery on the car is just over 1 year old.
