My HDJ81 came stock with Dual Batteries and an OEM Electric Winch. I don't have the wiring diagram so am not sure how these batteries are wired. I can see that winch wire connected to the battery on the USDS side. I can see some "glow plug" wire connected on the battery on the USPS side.
How are the stock dual batteries on HDJ81s wired? I saw some dual battery setups on US 80s and they had to use some sort of battery switch and power distribution blocks. Does anybody have wiring diagrams/schematics for HDJ81s?
Also, I seem to read somewhere that since HDJ81s have 24v starters, during cranking, the two batteries are "in series" to give out 24v. Then after engine starts, the two batteries are "in parallel" to give out the usual 12V. How was this feature accomplished? Or this is not the case for my HDJ81? What happens if one battery fails? I will not be able to start my 80 right?
How are the two batteries being charged by the alternator?
Assuming I replaced both batteries at the same with new ones. After say 2-3 years of normal use, would I expect both batteries to have the same charging capacity left? Or they would not be the same? And if one is about to fail, I should always replaced both batteries at the same time?
Lastly, on HDJ81s, which is the primary and which is the secondary battery? Primary is the USDS side? Or USPS side?
I saw this pic from wussy_pup. I don't have this sticker on my hood. But because of this cautionary message, I'm thinking that I should advise also my family members who drive our LC80 not to just jumpstart from any battery. But to jumpstart other cars in trouble from the secondary battery. But which is which?
Maybe somebody with JDM80 experience can enlighten me.
