one of my customer's resistor has gone out on his heater blower motor. would it be the same voltage drop as a resistor for an ignition coil?
I bet your local junkyards have a few.anybody have a good used one?
...and more resistance.The blower motor uses more current than the ignition coil so the resistor needs to have a higher wattage capability.

Since the blower draws ~20A, the resistors have to dissipate ~50W of heat.
man, you guys lost me a long time ago with amps vs watts, i never did learn that.
My '83 never had a resistor, and I don't remember what was in Frank's '75, so it surprises me that yours is a 200W.
If so, it SHOULD work fine, as long as it's in free or forced air (so it can lose that heat), AND your connections can take the heat. If you confine it in a wiring harness or even wrap it with tape, it'll start a fire. That's why all blower resistors are built to go in the airstream, and are bare.?
Your ig. resistor is probably ceramic-cased, right?
Just wait 'till he starts talking calories then!

Not in the switch - in the electronic ignition module. ;D It receives full battery voltage on both the cranking & running circuits, but it regulates what it sends to the coil.Did they just regulate it directly in the switch then?
Yeah, that falls into the category of "baffle 'em with BS". Typical US marketing misdirection & obfuscation....it's "variable based on ambient temperature", if I'm reading their add-type correctly, but it seems to me that all resistors are temp-variable. Wouldn't they be?
Not necessary.I can send you the image and text from the catalog...
