    HJ60 sudden overcharging

    Thanks for the great info and found a lot more your signature links :-) Will definitely look into using a converter or equalizer ASAP. Any recommendations?

    HJ60 sudden overcharging

    Thanks for the feedback. My cruiser has all stock components and I've had it for 20+ years so unless something went wrong I would say the alternator design is fine. ;-) Shot regulator yes, could very well be and I thought so too. I tested it according to the manual though and everything is...

    I thought so too. Battery config or additional loads shouldn't suddently make the whole system stop working as it's supposed to. As I mentioned in my post above, I re-adjusted the regulator and now things are working as expected. Will drive it for a few days and see.

    HJ60 sudden overcharging

    For everyone reading this, I was not able to identify what caused this sudden overcharge, perhaps the fixing of bad wiring connections done by others, not sure. In any case I adjusted the regulator as per the manual and everything seems to work ok now. Still need to drive it but at idle and...

    Yes I was not aware of this and after some research you're indeed correct. The options are an equalizer or a DC-DC (24-12) converter as you mentioned. With low loads on the 12V circuit a converter should be enough but I need to do some calculations.

    HJ60 sudden overcharging

    You are correct... did some research and indeed there's an imbalance now and I need to install a battery equalizer. But this doesn't explain the problem I'm having. Today I adjusted the regulator as per the manual and now everything seems fine. Measured the voltage at the alternator B terminal...

    HJ60 sudden overcharging

    Thanks for the info. I don't understand however why the system would overcharge. Voltage regulator should keep it within "adjusted" range shouldn't it? As I haven't touched it and it worked fine until 3 days ago, it should be max 29V approx. The additional accessories don't consume much. If...

    It's the factory (2) 12V batteries in series.

    HJ60 sudden overcharging

    Hi, thanks for your very quick reply :) The batteries are in series yes. This is factory, as the whole system is 24V unlike the FJ which is 12V, unless I misunderstood what you were trying to say. At idle voltage meter will show around 24V which is fine. As soon as engine is revved up quickly...

    HJ60 sudden overcharging

    Hello, I am new to ih8mud and what an amazing place to share our love for cruisers. I own an HJ60, which I am now 'fixing/upgrading' and live in Africa. First of all I would like to thank all the people that participate and help one another. I've been reading many of the threads as I recently...
