I had a similar problem on my '97. The battery voltage seemed OK at the coil and it seemed to charge right up and the problem still existed even with the battery charger connected and the battery fully charged. One or two of the cells read a bit low after it was fully charged. Once I replaced the battery the problem disappeared. Good luck. |

Repaired the wiring and it's been fine ever since. When you do find the cause, let us know. Good Luck John Normile |
