This morning I was taking my 96 GT for its annual ministry of transport test, half way there the ABS light came on. I pulled over and cycled the ignition and it went out. However when I started the car again, the volt meter was bouncing up and down, the battery light came on and my clock & headlights etc started to flicker with the revs of the motor (which was suddenly a little bit lumpy). This continued during my mot test, then after about 30mins, it just went normal again, it passed (hooray) then I drove home again with no issues! I will add actually that I went through some deepish water (slowly though) on my way to the test station, could my alternator be on its way out or did something get wet? Also the indicator light on the battery (new last year) was showing black (meaning it required charging) by the time I got home the indicator light was green (meaning it was fine again). Any ideas would be appreciated, thanks!
