2008 saloon EX 2.2 with 207722 miles on clock. First day alternator and three year old Bosch silver S5 battery. 20 miles into my 31 mile return home for work, the VSA warning light came on, then the ABS one. Then a few secons later, they go off, back to noral and a few seconds later off we go again. Dip headlights were on at the time. Wipers were on for about 5 miles( did not notice any slowing down of wipers) engine felt OK. I then said I would do a reset by restarting, car would not restart, dash light flashing. Got out my Fluke AC/DC voltage and current meter and 11.5 volts on battery, when I turn the key, dropps down to 5.8volts. Got my son to call around and he has a 1.6 TDI 2012 Jetta. Connected up for ten minutes and without the VW started the flow was 2.8 amps to the Honda. Once started 17Amps, and 21Amps at the end. Started car and drove home the ten miles, kept all aux power off. Felt ok going home, no warning lights on. When home, kept it running. Voltage is 13.5 and turning on the lights with the car ticking over, you hear the engine revs go up and the back down after the lights go off, this would say the alternator is working ok. No power or starting issues ever with the car. I need to get a new battery for a generator, so I might put this in the booth for the next week and keep the jump leads in there as well. Any one have any problems like this before, say loose connections ECT?
