are you running a pump controller or pump straight off the battery?

My pump controller did that to me; I ended up buying another battery.  Then I knacked my flow controller because I connected the battery terminal up the wrong way one morning **poof**.

I binned the controller and my old battery works great; I get at least a full days work out of it - and it's been a year since my old flow controller has gone.

Bin the controller and just work with a fast flow.  You'll find 100 meters of microbore will give you enough resistance for a perfect flow and you'll not have an over-priced, over-sensitive, over complicated lump of flow controller to mess you about.

do you use a tap to control the flow or flat out? on my backpack if I use the tap to control the flow it pulls a shed load of amps,battery goes flat in no time.

on mine if you press the button to switch it off (funny arrow type sym) briefly while running the pump it tells the batt voltage. should be about 12v ish when engine not running and 14v ish when it is. that should tell if split relay is working.

Best done with a lump hammer.  Hopefully someone will come along and be more helpful to you.

Putting a lump hammer to it is senseless. The hammer could cause alsorts of needless damage. Remove the wires from the controller. Wire the pump up direct to the battery..i.e red wire to red wire and black wire to black wire. Then once the controller is safley off, just jump on it with a big pair of boots.

If the battery is ok, then there is an issue with your setup after the battery. If it used to work fine but isn't now, what has changed that could have caused the problem? Are you using the correct size of cable and are all connections good and tight. We found that the worst place for a poor connection is at the inline fuse holder. If you are using crocodile clamps at the battery, change them to proper battery clamps.

As has been pointed out by another poster, your battery fully charged will read around 12.8v. With the engine running it will be anything from 13.8v to 14.4v. If you don't get that voltage, then there is something wrong with the Split Charge Relay setup. There should be an inline fuse holder very near to the van battery. Check that first of all. If your setup is wired to earth using the van body then make sure the connection to the body is good.

We use a seperate SCR and we need an earth cable from the Leisure battery to the van's body to work.

The spring controllers are designed to shut the controller down when the voltage drops too low to protect the battery from being wrecked.
