The heating element is working like it should believe it or not. No continuity between the case and ANY of the terminals. Complete continuity between all the terminals at room temperature. No broken wire and wire is not touching the case. Is the heating element supposed to have power going to it when the dryer is off but plugged in? I haven't probed it yet but that's my guess as to what's happening.

Check this first attachment down loaded and check vent and good idea to replace thermostat on heater too .Than attach vent to dryer and i use a test light on the cycling thermostat to make sure its cycling on the right thermostat.Of croase you leave back panel off for this test.Also can use a voltmeter.

There is a switch on the motor that closes once the motor is running. Once the switch is closed it lets voltage go to the heating element.
When the motor stops running the switch should open and kill the power to the heating element.

This motor switch could be bad if you have voltage to the heating element when the dryer motor is not running.

You can not replace just the switch as the switch only come with a new motor. The switch could be stuck if it has heavy lint build up.
It could also be stuck if the contacts are pitted. Some people can clean the switches/contact to make them work again, but I find this is often a temporary fix and sooner or later the motor needs to be replaced.

AJ is correct.
Your centrifugal switch on the motor is most likely stuck in the closed position.

 AJ, thanks for the video link and thanks everyone for your help! I'll tear into it today (after the Daytona 500 of course), I'll post what I find. Sounds like I'll be weighing the merits of fixing a 13 yr old dryer or buying a new one (wife wants new one).
