Fuel and Temp gauge issues

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

You are going to have to be more specific about where to where you are connecting your meter

You can use a fuel sender to check any gauge, oil, temp, fuel, just set the sender to the desired resistance. When you get a setup that won't work check for voltage in order.......from IVR output.........to the terminal on the gauge hooked there.......through the gauge........and to the sender. If for example, you read 5V at the sender, you know the sender is losing contact. If the IVR 5V goes away, you know there is something wrong right there, in the IVR itself or the contacts where it fits

DONT FORGET TO GROUND THE CLUSTER when testing
