You could have high resistance connections at the battery, starter and alternator. I like your approach of checking for excessive voltage drop and/or heat at each one. I have an 850, which is different, so I'm not familiar with the resources available, but a search shows that one good spot to read u...

Seems as though the drop is between the starter and the alternator. The b+ output on alternator gets really quite hot-- ive just nwo burned my thumb testing it. Could this still be battery pos cable from term to starter? or from starter to alternator? If so are there any write ups or ideas for how ...

Drove 1500 miles no problems. Then recently I was unable to start the car at work parking lot. No crank no start. Single cli...

Got home with locking jaw pliers. Replaced the terminal bolts with brass bolts, temporarily until I...

I picked up a cable at a parts store and when i went to check the connections to see if the cable was the rig...

30 seconds of propane heat on the lug bolt, then let it cool.
