In my response, I assumed the load-test was done and showed fully charged batteries. If this assumption is incorrect, please test the batteries.

Ether is something not recommended for these engines. To each their own, but I won't use ever use ether on my engine.

 

they are good hahahah! they did a load test put out 1600cca ...my truck cranks really really fast just no fire either for a couple of seconds or no startup at all

 

If they did the load test while still wired in parallel then you test was no good

 

ok well I doubt its that.. those batteries are hot and i know that but its fine if yall think that
