It has run all right since then but I am seeing much lower > voltages: say 13.7 or 13.8. oh now that ive read it again, maybe you have a weak battery and thats why you get around 9 volts when cranking, (mine does around 10.5) and then more than 14V while driving because the alternator is putting out current like mad to charge your weak battery. 13.7 sounds alright, its just a bit on the high side. my car does like 13.0 V when running bye simon
