Loosing most of voltage after attempting to crank
O7 Ranger won't crank or start. New starter & battery. Checked that it had 12 volts at starter. 1st Attempt to turn key, lights are all on & it clicks once & nothing. Release key. 2nd Attempt, no click, no lights, no headlights, nothing! Check voltage back at starter again, dropped to 2.86. Wait 30 seconds or so, dash & headlights back, along with 12 volts at starter. Any help or suggestions? Thanks!
Это хороший вопрос?
It can be bad cable lugs on battery, bad battery wire or loose contact on that power wire. Also check wire which going from battery to starter.
Usually voltage drop caused by bad contact somewhere.
