How to test fuel sender

ok reinstalled new sender into brand new tank. Filled tank. Turn key on and the gas gauge (and temp gauge?) starts to creep up to 1/4 full, 2 seconds pause, then gauge goes back down to beyond empty, like all the way to the left. remains dead while I drive. If i turn off car for a few seconds, then turn key back on, the gauges do the same thing as above.

Any idea what this means? I had tested the Gas gauge off the car using 3 D batteries and I was able to get the gauge to move to 3/4 full.


Recap: New cluster board, new voltage limiter, new Fuel sender unit.

Is it possible that the voltage limiter is wrong or bad or would bad limiter also effect other things?
