Guest marcusheawood Posted July 17, 2005 Report Posted July 17, 2005 ...sounds like your battery/charging system maybe iffy. Quote
mark1rev Posted July 17, 2005 Author Report Posted July 17, 2005 how can i check ? with a amp meter ? and what should the autonator give out Quote
Guest marcusheawood Posted July 17, 2005 Report Posted July 17, 2005 Output from the alternator at 2000 rpm should be about 13.5 volts or so. If readings across the battery are 12 volts or less then your alternator is suspect. If you switch on the rear window heating your revs may also drop. Charge your battery overnight, see if it happens the next day. :angry: Quote
