One of the first things a new M70 owner should check is the charge cable from the alterator to the B-post.
Since the cable runs just above the exhaust it gets too hot and the insulation fails.
The copper cable corrodes which raises its resistence leading to fires, low
system voltage (caasues a lot of problems), and battery failure.
The main part to check is the wire as it leaves the metal support pipe --
fairly easy to see -- grab the cable and twist it slightly -- the
"good" looking insulation may fall off!
Repairs are given here.
One result of ignoring the problem is shown here.
what a bad cable looks like -- the bright shiny copper wire was attached to the alternator.
