    Hi Guys,I hope someone can help me. We were due to go away for the weekend this evening, but the engine wouldn`t turn over as insufficient battery charge, so weekend aborted, doh! We haven`t driven the van for 3 weeks, and I usually just put on the EHU and give the cab battery a boost for a few hours as its let us down before, but charged up sufficiently to start up. This time the boost obviously didnt work! I have access to a 12 volt tester, and my question is, how can I be sure its the battery that isnt charging, rather than the charger not charging this time? Hope that makes sense as I dont want to waste £100 on a new battery if its the charger thats faulty

    put your test meter to DC voltage, measure across the battery terminals... if charger working it should read between 13.8 and 14.4 volts.

    charger off and battery fully charged 12.6v

    And for the future, if the van's on your drive, leave it on EHU full-time while at home. ;)

    Should the battery discharge in only 3 weeks unless its not holding charge?

    New battery duly fitted, although the one in the cab was a 700amp battery, but vehicle should have a 620amp, which is what was fitted. Cranking fine, and alternator working fine. I wonder why there was a 700 in there?
