How to test unknown fuel gauge.

Del, weren't you going to try to make testers for the gauges??/ We cracked the code a couple of years back for the resistors...

@halifaxhops was also going to try to copy one and I have one of his prototype gauge testers that are battery powered...

Those can be used to test the gauge sweep...

Going to work part time ate up a lot of time LOL. Yes, really, you can get by with the three resistors, you don't even really need a switch, you can just "alligator clip" them. I've forgotten what wattage they should be as they do draw some current. 1 watt would probably be safe enough for the short time you are testing
