Had a recent episode with my D1. I currently run 2 optima batteries with a Hellroaring isolator/combiner. On 2 occasions, I started the truck - tach and spedo dead. The first time it was a cool (<50 degree) morning, the second time it was warm. I thought my alternator was dead, but I had to drive the truck a short distance anyway. As soon as the truck warmed up a bit, everything came back to life...both times. Since then, the truck has not had a repeat of the same issue.
Sound familiar to anyone? Ideas?
