Clarke Jumpstart 4000, a few months old, only used once to start a car, and once to inflte a matress via the 12V socket; always kept on trickle charge, kept in the house. Anyone have one who can answer this for me please?
Two queries:
1. It is giving out a permanent alarm sound, nothing I can do to stop it. I understand the alarm usually sounds if you get the pos/neg the wrong way when attached to a car battery, but it isn't attached to anything. Turning the on/off switch does nothing.
2. It also has a 12v (cigarette lighter type) socket, which is working whether the unit is switched on or off. Is this correct, or is it highlighting a problem linked to the main problem above?
The unit is fully charged.
Any help woul be great, I'm thinking the unit has failed in some way.
Thanks.
