Bench Test Anti Slosh Module DAC7624
My fuel gauge is off by about 1/4 tank. When I fill the tank up, it shows as 3/4 full. When the low fuel light goes on, I only get as much as 14 gallons in the tank.
I bought a spare on eBay and it's actually not working at all....oh well...
Is there anyone that knows how to diagnose these things? I opened one up in hopes of finding a bad solder joint, but all "looks" good to the eye.

Vee,
As you probably know, the A-S module is designed to smooth the voltage output signal to mitigate the changes of the voltage input signal that occur because of the inevitable tank level movements incurred through acceleration, deceleration, cornering etc.
The problem happens because the capacitors in the A-S module which are used to support the voltage control "leak" over time. The resulting reduced voltage signal then causes the lower gauge reading.
Repair of the unit involves replacement of the capacitors. I have seen somewhere a specification for some suitable capacitors and ill try and dig it out if I can remember where I saw it.
cheers

Vee,
Removing the module and jumping those 2 terminals will effectively give you a straight pass-through of the voltage signal from the sender direct to the gauge, together with any expected fluctuations as the fuel moves around. Be aware thst you will lose your low fuel warning light which is driven only if the module is in circuit.
