need some help please
so, my skoolie isnt starting. im in a colder area and its been low temp for awhile now. add to that the constant use to open and close my doors daily.
i have tried the following:
jump skoolie with 700 amp and 1000 amp jumper box. skoolie didnt start no new issues.
charged the batteries with a 12 amp battery charger. attempted start a few times, have the diseal being heated. skoolie didnt start still, now i also have a buzzing like and alarm coming from my mini electric panel.
i just purchased new 800amp batteries to replace my 700 amp current batteries. plan to replace them in the daytime tomorrow. if that doesnt work, what is my next suggested step to start the skoolie? also should i test all my breakers or is this all a battery relates issue?
