what would be the function of a resistor 36,000 ohms across leads on non polarized electrolytic capacitors in a roto phase phase converter
As a safety measure, capacitors are expected to discharge to a safe voltage level (something like 50 volts or less) within a short time (something like 30 seconds or less). If the nature of the circuit is not sufficient to assure that, a bleeder resistor is connected across the capacitors.

Rather than repair a circuit by trial and error, it is better to have some understanding of the circuit and proceed based on analysis, measurements and tests.
