Well, Ive exchanged the V.R. with a new one. No difference.

I get a voltage reading at idle with the car warm of 12.9 to 13.07 or something close to that. Never hitting 14 unless I rev it up.

Belt is relatively new, battery connections are spotless and tight.

I couldnt get the car started the other day because the battery was dead. So its obviously not charging enough. I have an Espar diesel pre-heater running on in to enable startups in the cold without electrical plug in. (had it for 6 years now)

It works great but I have to let it run a good 30-min to an hour for a fully warm engine. (one that I can switch-over to WVO immediately).

So next thought Im having is perhaps the Alternator itself...
