Lennox HSI series: model number illegible

Lennox HSI series: model number illegible
Lennox HSI series: model number illegible.
Got a question about a Lennox HSI ac. +25 years.

Hotter than a pistol and not running, no gas and contactor pulled.

Resistance showed open across both windings. Wiring diagram did not show an internal OL or external OL, all though the terminal cover looked large enough to hold an external type. But I was running out of day light and the comp was too hot to touch.

Who's know if the OL is internal or external?

Chances are it has a Bristol compressor with winding stats.
