- 6v system, gauges are still original
- Gauge needle jumps to E when ignition is turned, doesn't move
- brand new sending unit from LMC Truck
- tested new ground, didn't work
- has at least half of a tank so should read something at least..
When you say, "Gauge needle jumps to E", where does it jump from before it ends up at E?
Your description confuses me when the very next words are, "doesn't move."
I don't understand how something can jump somewhere, and not move, at the same time.
