[TR] Installing a electric radiator fan in a TR4A

[pethier at comcast.net]

Absolutely NOT my experience with the TR4 and the Stag.  Each worked just fine with an electric pusher and the stock mechanical fan.

The Stag has a thermostatic pusher. Seamless operation.

The TR4 had a pusher with a 30-amp switch under the dash.  I only needed it when the car was stuck in traffic or "cruising" with the street-rod crowd.  In those situations, it quickly brought the temp down.
