My latest Vectrix has a charging problem that I would like to diagnose and fix.
When I turn on the charger, the headlight (and front/rear lights) come on and stay on, the battery cooling fans start up but the speedo does not move to indicate any charging current and the battery meter fluctuates between 15 and 16 bars and occasionally reaches 17 bars . After about 5 minutes everything shuts down again (cooling fans stop and the lights and dashbord instruments all go off).
According to my energy meter on the house supply it is actually drawing about 100-200 watts and the voltage does seem to be slowly increasing each time, but it is definitely not charging correctly.
I started today at 129.3V and it went up to 130.7V after the first session. I switched it off and on again and it "charged" for another few minutes and the voltage rose to 131.7V.
As there is obviously a serious problem somewher, I do not want to keep going with the short charging bursts in case I cause more damage.
When I turn on the ignition the estimated range now shows zero and the battery capacity bars just seem to vary with motor load (albeit with a delayed response) so I presume it is now simply working as a voltmeter.
Does this mean that it is definitely a charger fault, or could it still be a problem with the motor controller or Interface Control Module?
I have already tried removing both plugs from the charger and leaving it for a few minutes before reconnecting them, but it has made no difference.
I would appreciate any suggestions on what to try next.
