Flat Battery - Split Charging Relay

Post by davejl »

Hi I've been having trouble with my 88 Joker 1.6TD main battery going flat; I had left it disconnected over the last few months whilst it over wintered in the garage. After reconnecting last week and starting first time I have to jump start the van today as the battery was partially discharge. It is no problem when the vehicle is run and it will start again within a couple of hours. So my thought is that it might be the split charging relay that is causing problems.
After I bought the van last year I fitted a leisure battery and a new stereo – but this was causing the main battery discharge (I’ve replaced the main battery – it had had it). I wired both stereo feeds (main & memory) to the leisure battery as the main battery was still discharging. I think that it is a ‘sticking’ split charge relay as there are no indicator lights on the radio (as there should be); this is then allowing the main battery to discharge as well.
Does this seem the right?
One other question where do I find the split charge relay (is it the one in the leisure battery bay (under the drivers seat)
Thanks for you help.

I had this issue
my split charge stuck on after the engine was turned off. I had to tap it to switch off the starter
simple answer is to replace it, they are very cheap and available from Maplin or any other electrical shop of the same ilk.

you could test it and such but that will prolong the inevitablle

there's a good one here with the fridge terminal aswell
