ABSTRACT:
Diagnostic apparatus, connected to probes for sensing conditions or parameters of an internal combustion engine during non-combustion cranking of the engine, reads electrical conditions at times related to the crank angle of the engine. Electrical tests are made at times indicated by peaks and valleys in the starter current or voltage waveform, the average of these providing load-compensated indications of true electrical parameters, to eliminate effects of battery loading variations due to compression-induced variations in cranking power required.
