CF433 Regulator/Rectifier Resistance Test Chart ('84-'85) - Terminal Ohm Values

This document is a test procedure for an electronic component (marked CF433) applicable to '84-'85 models, showing how to check it with an ohmmeter. A photograph at the top identifies the unit's terminals and their wire colors: IGN (Black/Yellow), SW (Black), EXT (Black/Red), PC (Blue/Yellow), E1 (Green), and E2 (Green). The instructions say to set the tester on the R x K Ω scale, with all readings expressed in K Ω. A resistance matrix follows, listing expected values for every combination of positive-probe and negative-probe terminal placement. Many combinations should read infinite resistance (∞), while specific pairings have expected ranges: EXT(-) to SW(+) reads 0.1-20 KΩ; PC(-) to SW(+) reads 0.5-200 KΩ; PC(-) to EXT(+) reads 0.5-100 KΩ; PC(-) to E1/E2(+) reads 1-5 KΩ; E1/E2(-) to SW(+) reads 0.2-60 KΩ; and E1/E2(-) to EXT(+) reads 0.1-2.0 KΩ. All combinations involving the IGN terminal read infinite in both directions. A hand-drawn arrow on the chart highlights the EXT(-) to SW(+) test point. A reader can use this to bench-test the component's internal diodes/circuits for failure.
