Bench Testing a Fuel Gauge with a Heathkit Decade Box
1 year ago
6
In this video I use a vintage Heathkit IN-37 Resistance Substitution Box (aka Decade Box)
to bench-test a 90 ohm GM fuel tank gauge.
You can use this same testing principle on any resistance based automotive gauge.
Heathkit sold similar boxes under the IN-12 and IN-3137 part numbers.
