My 92 Aerostar needs an antislosh module. Are they still available? Where?
By the way, it helps to use a meter that works when measuring resistance in the sending unit ! I decided to check it one more time with a different meter before I ordered another one. Guess what?! The new one worked fine.
I definitely traced it to the antislosh module this time. Oh well! Win some, lose some!
First as suggested check for solder breaks and repair them as necessary if you can't find any.
Check for faulty components check the diodes with your multimeters diode checker make sure you touch the negative probe to the end of the diode with the black band and the positive to the other end.
Also check the resistors for correct resistance with your multimeter. What is a resistors proper resistance you ask look at the color bands and they tell it to you. Here is a site that does the converting of the color bands to OHMS for you.
As for ICs the only one you'll come across in an OP Amp which is a common IC you can purchase at Radioshack for about $1.49 if its an OP Amp there will be the letters LM printed on the IC followed by numbers for example LM-524N in this example don't worry about the N LM-524 would suffice. I have blown out a couple of these myself on electronics projects just a little current in the wrong direction or on the wrong pin renders them useless. However its all or nothing either the IC doesn't function or it does.
But what I think is wrong with your slosh module is a capacitor isn't storing current which allows the needle on the gauge to remain in the same place (the current to remain constant on the fuel gauge) even if the potentiometer in the gas tanks resistance is going up and down. You are likely to see one of two types of capacitors either axial or upright axial just means its a capacitor on its side.
You can pick up your replacment parts at Jameco.com at a substantial savings.
If your adventurous while this would be no problem for me if your new to electronics it may seem a little confusing .
