split charge relay problems

[coolcampers]

Hello all
if a split charge relay is working properly, should it be possible for it to drain the starter battery? I have a relay that automatically senses the charge and diverts current to the leisure battery. However, recently, when i have been running things off the LB and it goes flat, it drains the starter battery. Do I have a faulty relay. I think its a smartcom relay.
thanks

Sounds like it's goosed I think it's only a 30A relay which, if your leisure battery gets too low, may well be damaged by the large charge coming from the alternator to the LB. I'm sure some more knowledgeable person will be along soon

Would fully agree with the above!
I always wondered why when you search for Smartcom Relay on google you see lots of adverts for packs of 5 or 10! Obviously people must replace them rather often ...

ok thanks for that. next question. can anybody recommend a good one? All the wiring is in place so i deont need the full kit, just relay

thanks

Any other relay won't have the same mounting arrangements. The most frequently suggested one on the forum is the Willinton kit, he will make up kits it seems depending on what you want, drop him an email via EBAY is the suggested approach http://shop.ebay.co.uk/willinton/m.html use the Contact seller button after selecting Seller info link.

The other thing to bear in mind is that the previous cables and fuses may not be adequately rated either.

For a bit less money and fewer bells/whistles etc I used a dual sensing kit from this supplier

Have to say the willinton kit looks the dogs b*****ks though!

It really is the dogs bits, and so is the after sales service. Lo

You can get a split charge relay at Maplins for a couple of pounds.

But you wont beat the quality and reliability of the Willinton kit.
I needed a battery tray too and so purchased the all singing all dancing kit including the tray...... Now with the 110Ah battery I have......nothing else comes close to be able to charge it as effectively...especially with the VSR modified perfectly for the Bongo and the additional fuse box and patch leads..... wins hands down IMHO .....AND you will only buy one....it's a kind of fit and forget component....
