    I've bought myself a new toy, a 2.4 tourer, with an existing fault of not charging.

    A new alternator and battery have been fitted by the previous owner, but with no joy.

    The charging light on the dash goes out as normal.

    Anyone got any suggestions where to look first?

    Cheers, Simon.

    Are you sure it's a charging issue and not a battery drain issue ?

    What steps have been taken so far to diagnose the issue ?

    Only bought it yesterday, so still running on the charged battery, but dropped in to a pal at KwikFit and he put his diagnostic m/c on the battery which confirmed it wasn't charging.

    Off skiing tomorrow for a week, so will be parked at Stansted, I'll take a spare charged battery and dig deeper when I get back.

    Next door neighbour RAC tech suggested a relay might be u/s.

    As an aside the car had been parked on a SORN for a year, flew through it's MOT today, brakes "as good as a brand new VW", CO emissions 0.01, just a couple of number plate bulbs out, and a front sidelight which just needed a thump- love the Honda build quality!

    A complete shot in the dark but is there any possibility that the electrical load detector (ELD) might be faulty?

    Thanks for the suggestion, what is an ELD and what does it look like?

    I pulled and re-inserted all fuses and relays I could see in a bit of a rush before packing for my hols, stuck my multi-meter on and it appears to be charging.

    Whether it is an intermittent fault or I've fluked it remains to be seen.

    Its a gizmo in the fuse block that detects the difference in load and battery to reduce alternator output to save fuel. Doesn't usually go but reading elsewhere can cause charging issues when faulty. Some of the more informed folks around here might be able to describe in better detail or give suggestions on how to troubleshoot.
