The method you used is good for testing the module on a Frymaster because that fryer’s module has a separate flame sensing wire/ flame electrode from the spark wire/ignition electrode. That configuration is referred to as “remote” sense.
In the case of his Cleveland steamer, the module is different. There’s no separate flame sensing wire/flame electrode. The spark and flame sensing circuits use the same wire and electrode. THAT configuration is called “local” sense.
The problem with REMOTE sensing setups is that you can’t be connecting your micro-amp meter in series with a circuit delivering THOUSANDS of volts for spark…and then expect it to survive that to give you some minuscule micro-amp reading. THEREFORE, many (but not ALL) module manufacturers either instruct a tech to connect the micro-ammeterin series with burner ground, or provide separate test points on the module to make a flame circuit reading.
Honeywell is not one to provide such test points, but Fenwal is.
