Hi all
I have a purefreedom flow control and my battery has a split charge relay (intelegent)
my problem is the battery reads 11.1 - 11.5 volts so I don't think the intelegent relay is working properly.
What tests can I do to check it?
The water flow isn't as fast due to the low voltage.
Please help Daz
Probably needs a supplementary overnight charge with a stand alone battery charger. Most of us don't travel enough miles everyday for the charge to be returned to the battery through the split charge relay.
If its a separate intelligent split charge relay (not part of a pump controller) then you should be able to run the engine with your pole connected up to the pump and see the pump delivering a better water flow. It may take some time for the relay to kick in as it dictates that the vehicle battery gets a full charge first before the aux battery.
First check is to find the fuses which should be very near the positive battery terminal posts of each battery to make sure they haven't blown.
We put our batteries on a separate charger every couple of days. Yesterday was a prime example of the issue you may be experiencing. On Monday I fully charged my leisure battery and both of us went off about a mile down the road to finish off a big job we had which took us 2 hours each. As the job was an atrium I guess that both pumps worked for more than 90% of that period, about 3 3/4 hours. On completion we drove home and parked up. I then put our 10amp intelligent leisure battery charger on the battery and it took about 2 hours to fully charge that battery.
On occassion my son will work a day with his van and drive a 40 mile round trip in the evening, and even in the summer, with no headlights on, his battery still wouldn't be fully charged when he came home and parked up. Both of us have 15 amp fuses protecting our split charge relay circuits, and in 6 years we have never replaced a fuse. So even with a big alternator (Citroen Relay van has 150amp alternator) the leisure battery isn't receiving more than 10amps charge or the fuse would have blown. So if his pump worked 5 hours and drew 4 amps per hour he has taken 20amps from his battery. If his split charge relay is delivering 10 amps per hour then he will need to drive for 2 hours to put the days use back into the battery.
