RE: (ET) E-20 rebuild report

I'm sure there is an ACCURATE way, such as a thermocouple mounted by heat 
sink grease to the mounting ribbon, and a heat-gun.  A 'quick' check is to 
pull one wire, put an ohm-meter across the interlock, and heat it with a 
heat gun to see if it opens.  On the deck motors, the worst case failure 
is to melt the wire running to that particular motor.  It isn't super 
expensive failure.

melt.  In heavy grass the interlock WILL trip, especially if the battery is
low or the blades are dull.

Is there a good way to test the thermal cutout - I'd like to know mine work
before they are needed! That goes for the cutout on the drive motor as 
well.
