Atlantean Posted December 27, 2013 Share Posted December 27, 2013 What are the outputs on the 063 battery you have? For that engine I would say you need a minimum of 400 CCA (EN) but higher would be better - just don't go bigger that what the alternator can handle!

autowatch Posted December 27, 2013 Share Posted December 27, 2013 Also check the engine earth strap to ensure it's clean and tight....first indication of poor engine earthing is slow cranking.... 1 Quote Link to comment Share on other sites More sharing options...
john p Posted December 27, 2013 Author Share Posted December 27, 2013 will look at a 065 tomorrow(I work at a motor factors)will also check the earth strap as it does crank over very slowly. thanks for the advice Quote Link to comment Share on other sites More sharing options...
mantasrme Posted December 28, 2013 Share Posted December 28, 2013 The 065 is standard recommended and the 075 is the heavy duty recommended. I normally fit 075's for the extra starting grunt Quote Link to comment Share on other sites More sharing options...
john p Posted December 28, 2013 Author Share Posted December 28, 2013 just stuck a 075 in and she fires up instantly cheers mantasrme Quote Link to comment Share on other sites More sharing options...
