So driving the other night me the battery light came on and off with lights dimming at low revs, also heater kept going off and a click from the passenger side of the dash.

Took it to test the voltage and battery with it being cold recently. Voltage running with everything on was over 14v. It came up with battery faulty. So replaced the battery yesterday and now this morning it's come on again!!!

Im thinking either alternater or wiring connection somewhere

Anything simple to look at before I start spending a fortune changing parts?

Cheers
