Standing current of VW Golf R
Further to a post a few weeks ago, about the battery being flat in my car
after standing idle for a few weeks. I subsequently charged the battery in the house using a laptop power supply and a couple of headlight bulbs in series to deliver a charging current of ~2 amps over several days. I eventually put the battery back in the car and fitted a knife switch isolator. Yesterday I went out in the car and returned after about 10 miles. This morning after the engine fan had stopped I measured the standing current across the open knife switch and was surprised to see the meter was reading 3.26 amps. No wonder the battery flat! |
