I have replaced both sender and gauge. Both came from same supplier. When first hooked up to 6 volts, gauge is pegged on 'Full'. This tells me that the most likely culprit is the wire from sender to gauge. Here is what I have:
1. Tank is about 2/3 full (measured 19 ohms at sender to ground).
2. Wire is continuous from sender to gauge, not grounded out.
3. Sender checks good at 0 to 30 ohms.
4. Sender body has good ground to chassis.
5. Gauge cluster has good ground to chassis.
6. Neither post on gauge is grounded. From SND post to ground measures 30 ohms with sender wire disconnected.
7. 6v and sender wire are both connected to the proper posts on gauge.
Sounds like a bad gauge. Any thoughts? Thanks for any input.
