Fuel and Temp gauge issues

Mike69cuda said
After market senders have a lot of known issues with accuracy. They are not an accurate reproduction of the oem sender. Search on the forum and you will find lots of info.

Checked again from prong to gauge tested .2 ohms

showing 26 ohms at harness plug but only showing 15 ohms at gauge when plugged to board

temp gauge I ran a jumper from sender direct to gauge no movement.

I have a spare set of gauges I hooked direct to sender as well grounded and used 5 volts to power and nothing

did same with fuel gauge and used sender and they both ohm the same and gauges move according

Sounds like you diagnosed your problem... Loose pins.
This cluster is measuring 3.8 ohms between pins and the pins are tight.
The fuel guage pins measure 0.4 ohms and feel just as tight.
