Cecil, If the starter turnes over properly, Your not experiencing a low voltage problem but maybe a relay contact sticking problem. When you connect the jumper cables, your surging the electrical system and releasing the relay. You might also try the main relay ( Tap on it ) when the problem starts over again, this feeds the ignition resistors and coil. If you don't know which is which, i can fax the info. Several of the relays are interchangable and the car will start and run without several of them. Example: You can take out the low, and high beem relay's and swap with others in a pinch. You just need to know which ones. John --- In dmcnews@xxxxxxxxxxx, "dmc1982" <dmc1982@xxxx> wrote: > This is a strange one. My DeLorean has failed to start twice now with the > following symptoms.
