A question about the 24v system. In our vehicle it is used for Engel fridges and external lighting. We haven't had any problems doing this for a few years.
I had removed all the batteries for cleaning both the batteries and the trays, as not only is there corrosion at the terminals but the exposed position picks up a bit of mud & debris etc.
When reconnecting, I have done up all connections excepting the battery links (the short black cable).
On preparing to attach this I note that there's a very small spark when reconnecting.
I do not know if this means there is a leak in the system or if it is the necessary open exitation for the 28v generator.
Advice would be appreciated.
NB I did check the useful FFR threads and AFAIK the subject hasn't been addressed
