Volvo Repair Questions? Ask a Mechanic for Answers ASAP
Hopefully i can help..
Sounds very much like you either have Battery/Charging issue..sometimes when a fault occurs usually Alternator related these items will shut down as the voltage isnt enough for them to operate correctly..the best course of action would be to check the auxiallary belt first to ensure that hasnt snapped or lost tension..then a proper check of the battery connections/earth points - aswell as the battery itself then the charging system alternator performance - by the sounds of your description it very much sounds like a charging fault..I do hope this helps
Brilliant deduction ,many thanks for your help.
