Thanks to all who put there cents in to my inquire!!!! Never thought I would get that much input!! Can anyone help???...OK...the gas gauge?....does it suppose to get 90 ohms full or empty?..The reason I ask...is that i heard it was 90 full...but when I put the wire ( straight off the sending unit ) to ground it reads " empty "...any other time it reads " full ".. Thanx again...

wow I could use information on this to. My gas gauge one day decided to peg ast the full mark and thats it. It will drop to E when im aaaccckkkk cough wheeeeeeeze on the side of the road and walking for gas.

I hope this helps . With GM gauges they use some kind of resister for their gauges . Putting it directly to ground sometimes this isn't a true test . I think if you use a volt gauge on the hot wire you should see a fluctution in volts .Also a good ground is important for these to work . If there is no good ground tank will read full and stay there.

If I recall correctly, when the ground is disconnected, the tank will read full. No power just the opposite.

I know that for the '69 - '72 Blazers, 10 ohms is empty, 90 ohms is full. Therefore, an open circuit on the sender wire, or a bad ground to the guage or sending unit will make the gauge go past full. A sender wire shorted to ground will make the gauge read empty. A bad sender could fail either way. I think the circuit is the same on the later model trucks / Blazers.
