Help needed please Flat Battery

Post by gasace » Sun Sep 26, 2010 4:51 pm

:( Hi everyone, just when everything was going well, I am in trouble again. Went to start the bongo after 1 week the battery was so flat that the alarm remote would not work. It was fine last week and I cannot find anything switched on, when I checked the voltage at the battery it was down to about 7 volts, so the battery has probably had it. Strangely the leisure battery was also down to about 7 volts this should not have been in use as everything was switched off. I have connected the electric hook up and set the charger to car and will see tomorrow if it has improved. It seems to me that a relay may have stuck draining the battery, but I don't understand about the leisure battery. Any ideas welcome. Also if anyone can recommend a good auto electrician near Southampton, one who knows about camper systems I would be grateful. :( :( :( :( :( :(

Many thanks

John

If both batteries measured exactly the same then yes the Split charge relay sounds like it has welded closed. I would suggest removing one of the split charge fuses and measuring again, if the voltages are different then that points to the split charge relay being the problem.
