Hey guys, I need your help. Started the Ranchero this morning, then shut it off to get something I forgot in the house. Came back, no start, just a heavy click and the interior lights dimmed. Tried it a couple more times after charging from the other car, then another click and all the interior lights went out. Here's what I've done so far: • measured battery at 12.63 volts, similar at solenoid • charged for 1/2 hour from another car running at 2000+ rpm • tapped on solenoid & voltage regulator (modern transistor type) • pounded on starter (original style) • checked fuses by kick panel; all look OK • jacked up rear end & spun tires in gear; not locked up • scratched head & looked confused Is there a fusible link in the system? Any thoughts or suggestions?
