How to crank a 5030?

[Seven Gables]

The thermostart on my 5030 is threaded into the front end of the intake manifold near the fan. When voltage is sent to it the wire coil gets red hot igniting the gravity fed fuel supplied by a small fuel line from tank. As the coil gets hot it opens a heat activated valve allowing the fuel to drip in.
I’ve had to replace one or two over the years in the 4 tractors I have that utilize a thermostart, the coil burns out.
