Wayne?wpoll? ok well wired up my basic dmm to the + in engine bay and the other probe touching the inner sides of the dc lighter socket, set it to 20V got a reading that looked ok for battery at rest 13.0V, cranked engine, dropped down to 8.98V....not sure how I am gonna get the amp draw of starter via this info? if it was my starter an issue would it have dropped much more than this
